Grandstand's coverage of the London 2012 Olympics continues on Day 13 with a gold medal to Australia in the men's K4 1000m at Eton Dorney.
8.50am: As if the 400m is not painful enough, American athlete Manteo Mitchell apparently did half of it with a broken leg! Mitchell was America's second runner in the 4x400m heats when things went wrong:
"I got out pretty slow, but I picked it up and when I got to the 100-metre mark it felt weird. As soon as I took the first step past the 200-metre mark, I felt it break. I heard it. I even put out a little war cry, but the crowd was so loud you couldn't hear it," Mitchell said.
"I didn't want to let those three guys down, or the team down, so I just ran on it. It hurt so bad."
8.06am: France will meet USA in the final of the women's basketball after a comfortable 81-64 victory over Russia. The Americans, who defeated the Opals 86-73, will go in heavy favourites despite France also being undefeated.
7.42am: While Usain Bolt is busy telling the world he is the world's greatest athlete, America's Ashton Eaton is preparing his rebuttal with victory in the Olympic decathlon with a total of 8,869 points. Silver medallist and world champion Trey Hardee was 198 points behind. Eaton broke Roman Sebrle's 11-year-old world record in June, but missed out on taking the Czech's Olympic mark of 8,893 by 24 points.
7.33am: Great Britain picked up three gold medals on Day 13, one in the dressage, one in taekwondo, and another to female boxer Nicola Adams. The 29-year-old Adams, who hails from Leeds and used to be a tiler and a TV extra, smashed China's three-times world champion Ren Cancan in the gold medal bout of the flyweight division. And now to celebrate:
"I think I am going to see the family, probably going to Nandos," she said.
Winner, winner, chicken dinner.
7.10am: Usain Bolt has given an explanation as to why he didn't put the foot down and try to break his 200m world record like he did in the Beijing final.
"I could feel the strain on my back a little bit so all I did was try to keep my form, run home and when I saw where I was going I stopped running because I knew it wasn't going to be a world record."
Well, I suppose that is fair enough. But he still managed to pump out a few celebratory push-ups... I want my money back. While we are on this bloke called Bolt, here the snaps he took when he .
Meanwhile, Yohan Blake and the boys are celebrating after receiving their medals at the Olympic Stadium.
Racers track club and Jamaica just did a little housekeeping tonight-clean sweep!!
6.57am: The Netherlands have dismantled Great Britain in the men's hockey semis, cruising through to the gold medal match with a 9-2 rout. The Dutch were well on their way after building a 4-1 half-time lead. It only got worse for the hosts after the break with Roderick Weusthof capping off his hat-trick from a penalty corner. Netherlands play Germany in the final after the defending champions defeated Australia 4-2.
6.51am: Earlier, American Christian Taylor won the men's triple jump, his country's first gold in the event since Atlanta. Long jump bronze medallist Will Claye took silver, and Italian Fabrizio Donato bronze.
6.45am: Australia's Kathryn Mitchell has just missed out on the top eight of the women's javelin final. Mitchell was ninth with an effort of 59.46, just missing out on a chance at another three throws.
6.36am: The United States have gone back-to-back-to-back in the women's football, defeating Japan 2-1 in the gold medal match in front of 80,000 at Wembley. Carli Lloyd scored a double for the Americans in the eighth and 54th minutes. Japan's Yuki Ogimi dragged one back on 63 minutes before the USA clung on for victory. Japan, which defeated the USA in the World Cup final last year, was denied a controversial penalty decision late on. Canada beat France 1-0 to take out the bronze. FIFA president Sepp Blatter was on hand to present the medals. Let's just say he wasn't given the warmest of welcomes in London.
5.56am: Men's 200m final - BOLT WINS! Usain Bolt has done the double-double. It's a long way between Beijing and London, but not if you're the fastest man on the planet. Bolt becomes the first man to win the 100 metres and 200 metres at . He takes gold in 19.32 seconds, with training partner Yohan Blake running well for silver in 19.44 and fellow Jamaican Warren Weir third in 19.84. It's a Jamaican clean sweep. Bolt was quick out of the blocks and before the bend he had the rest of the competitors in his dust. Blake finished very strong but that says something about how far ahead and how quick Bolt was travelling. In fact, the champion sprinter let up well before the line, preserving his world record of 19.19 from Berlin in 2009. Bolt and Blake celebrate together on a lap of honour. Now Usain has taken a camera off one of the tens of photographers milling around him and is snapping shots of a posing Blake. This guy is a hoot. This guy is the best ever.
5.40am: Coming up next in 15 minutes, Usain Bolt attempts history. Can he do the 100-200 double at consecutive Olympics? Training partner Yohan Blake will be his biggest competition. The two Jamaicans could have the rest of the field shattered by the bend and by the finish? Who knows, it could be sub-19 seconds for the first time ever.
5.30am: The Americans qualify fastest for the women's 4x400m ahead of Trinidad and Tobago and Ukraine. Jamaica survive a baton-change scare in their race, but qualify fourth fastest.
5.12am: The Stingers have bounced back to defeat Hungary 13-11 in extra time. Gemma Beadsworth scored a double while the Aussies kept Hungary scoreless down the other end after the teams were locked at 11-11 following a dramatic finish to regulation time. That would have been just heart-wrenching if Australia lost that medal. But the Stingers collected themselves magnificently and now have a bronze to match their effort in Beijing. Two medals in a matter of minutes for Australia.
5.09am: Women's 10m platform final - Australia's Brittany Broben has claimed an amazing silver medal in the 10m platform. At just 16 and in her first Olympics, Broben produced a brilliant final dive to finish with a total of 366.50, behind China's Ruolin Chen (422.30). Melissa Wu finished in fourth just 1.1 points off bronze medallist Pandelela Pamg of Malaysia. Broben was second after her third dive, but her fourth effort scored just 57.75 and she dropped back out of the medals. But the year 11 student from Benowa showed composure beyond her years to nail her final dive (a back 2-1/2 somersault with 1-1/2 twists) for a score of 81.60. She then watched on nervously as only the defending champion Chen could pass her total. A star is born.
"I just wanted to do it, I really, really wanted to do it. I almost fell off the platform because my legs were so shaky, but I tried to disguise it a little," Broben said of her last dive.
"I saw my coach's face and I've dreamt about that moment, seeing his face after my dive. It just happened and I can't believe it."
5.03am: Men's 800m final - WORLD RECORD! Kenya's David Rudisha has run 1.40.91 to win gold. The first man in history to go under the 1:41 barrier. And he has done it in an Olympic final without a pacemaker. This guy is a Bolt-like freak. Botswana's Nijel Amos takes silver in a time that is the equal fourth fastest in history. Timothy Kitum finished with the bronze in a personal best time. In fact, all but eighth-placed Andrew Osagi ran a personal best in that race and - now this is the crazy part - even he would have won the gold in the past three Olympic Games. They were going flat out.
4.53am: Drama in the bronze play-off. Australia looked certain of claiming a medal after holding off Hungary's final chance for an equaliser. But in the dying seconds, Hungary's Dora Antal sneaks up on Stingers keeper Alicia McCormack, steals the ball and scores to send us to extra time. The Aussies are in disbelief.
4.49am: Meanwhile, Australian gold medallist from Beijing Matthew Mitcham, who has been a valuable source of information at the Aquatic Centre, has been told to lay off the tweets.
Umm, just found out that I could have my accreditation revoked by IOC for tweeting scores, SORRY GUYS, I NEED TO COMPETE TOMOZ!!
He followed it up with:
So in the mean time I'll tweet non-specific commentary that should keep me out of trouble... Unidentified blonde girl gets a strong reaction from crowd and judges for her dive.
4.35am: Broben has jumped up to the silver medal position after a cracking third dive. Only two more to go, she could hold on for a medal.
4.29am: Australia's Melissa Wu and Brittany Broben are off and diving in the women's 10m platform final. Wu has a score of 150.00 and the 16-year-old Broben 143.95 after two dives and are placed fourth and fifth respectively.
4.15am: The Stingers are on track for a bronze medal, holding a 7-4 lead over Hungary at half-time. Gemma Beadsworth and Ash Southern have two goals each.
3.55am: The Stingers are leading Hungary 2-1 after the first quarter in the play-off for bronze in the women's waterpolo. Can the Aussies pick up another bronze to match their efforts in Beijing?
3.42am: Full-time. The United States prove too good for the Opals, prevailing 86-73 and progress to the gold medal match. Australia couldn't replicate its early intensity, which delivered a four-point half-time lead. The Opals struggled with their consistency all through the tournament, and were unable to dig themselves out of a hole when the Americans piled on a 8-1 run at the start of the third. Liz Cambage looked particularly tired, unable to add a point to her terrific 19-point haul in the opening two quarters. By shutting down Cambage, the USA blocked a major avenue to the hoop for the Aussies. Lauren Jackson had 14 points and a whopping 17 rebounds. America's Diana Taurasi lit up in the second half to finish with 14. The Opals also lost key defensive player Jenny Screen at half-time, which did not help to keep the red-hot favourites at bay. Nevertheless, a brave effort by the Aussies, who may now rue having to face the Americans in the semis and not the final. The Opals will now play-off for bronze against either Russia or France on Day 14.
"I think their zone really shut us down [in the third quarter]. I know I backed down a little bit. I put a lot of that on me," Cambage said.
"They went to zone and I think that shook us up a little bit.
"They came out fighting after half-time and upped their defence. They came out fighting and we went down fighting."
Captain Lauren Jackson said her team can hold their heads high.
"We played hard right until the last minute. It was just one of those games where they pulled it back. We played our hearts out. Now we have to regroup and try and win the bronze medal.
3.37am: The AOC has realised details for the Australian athlete welcome home parades. This may not have been our most successful Olympics campaign, but you can be sure our competitors have given their all whilst representing the country with pride in London.
3.18am: The USA predictably fight back and take a 65-59 lead at the end of the third. The Americans outscored the Opals 22-12 after half-time with Opals star Liz Cambage not scoring a point in that period. The underdogs need to start tightening things up if they are to pull off the upset.
3.16am: Gold for the fighting Irish! Four-time world title winner Katie Taylor stands up to all the pressure and wins gold for Ireland in the women's lightweight. She claimed a tight 10-8 decision over Russia's Sofya Ochigava to the delight of the massive Irish support at the ExCel. Amazingly, it is 20 years to the day Michael Carruth won Ireland's last boxing gold in Barcelona.
2.40am: What a first-half display by the Opals. They lead the USA 47-43 after the opening two quarters, with Liz Cambage having a day out with 19 points of 8/12 shooting. The 20-year-old star also has only one foul but has drawn five as Australia got the USA in early foul trouble. The Opals have eight scorers in total, while captain Lauren Jackson is leading the way with eight defensive boards. American captain Sue Bird has 10 points. Consistency across four quarters hurt the Opals in the group phase but if they keep up this tempo they could be on track to defeat the four-time defending Olympic champions.
2.19am: The Opals take a 22-20 lead into quarter-time. Fantastic hustle by the Aussie girls, especially Liz Cambage with 10 points of 4/5 shooting. The Opals are avoiding foul trouble early as well, which has been of concern against competitive opponents.
2.11am: Heaps of action in the BMX motos with Australia's Sam Willoughby and Khalen Young making it through to the semi-finals. Team-mate Brian Kirkham was not as lucky, missing out by four points. There were plenty of spills in all four heats. Brazil's Renato Rezende and New Zealand's Kurt Pickard came out worst, both unable to complete the quarter-finals after crashes in the second and third races respectively.
2.11am: Hopefully Australia has more luck in the semi-finals of the women's basketball as the Opals face old rivals USA. Australia leads for the first time 16-14 with just over three minutes left in the first quarter.
2.00am: Full-time. Germany has defeated Australia 4-2 and is through to the gold medal match. More pain for the Kookaburras. They'll play off for bronze against either Great Britain or the Netherlands. But they came here for gold and the reigning world champions and four-time defending Champions Trophy winners have fallen short again. Shades of 1984 and 1988 where Australia was also favourites for gold. Full credit to the Germans, who are ecstatic out there. They were relentless in fighting back from 1-0 and 2-1 down and their defence was outstanding against an Australian side that scored 23 goals in the group stage. This one is hard to take for all Australian hockey fans.
Nobody say choke.
"I'm devastated. We worked really hard for this match and it's sad for us not getting the result that we hoped for," said Kookaburras keeper Nathan Burgers.
"We always knew they were a really good team, we didn't expect to just walk out and win," forward Glenn Turner said.
"We made a few mistakes today that were uncharacteristic. We played better in the first half than Germany, but in the second half Germany went for goals."
1.51am: Dear, oh dear. It's all falling apart for the Kookaburras. Germany pinches a fourth on the counterattack by Florian Fuchs and it is now 4-2. Australia needs a minor miracle now with seven minutes left.
1.47am: Double trouble. Germany has scored again thanks to their clinical penalty corner work. Like a well-oiled machine. Timo Wess puts this one away and it's Germany will one foot into the gold medal match with a 3-2 lead. Can the Aussies respond within the remaining 13 minutes.
1.40am: The Germans are level at Riverbank. Some sloppy defending from the Kookaburras and they are duly punished by Matthias Witthaus, who makes it 2-2 with 17 minutes left.
1.38am: Olympics reporter Karen Barlow () tells us the men's 470 sail-off between Australia and Great Britain has been postponed until Day 14 due to weather conditions. They'll race for gold at 9.00pm AEST on Friday.
1.36am: The Kookaburras hold a 2-1 lead over Germany in a cracking semi-final. The Germans have just had a wonderful goal disallowed for dangerous play. Oskar Deecke was on the end of a long ball, controlled it magnificently on the run, but raised his stick above his shoulder when he poked it past Aussie keeper Nathan Burgers.
1.34am: Well played, Andrew McGarry. Our resident Olympic tragic finally got himself a gold medal whilst on duty. Much deserved.
1:30am: Well folks, it's been a great golden start to the evening thanks to the men's K4, and I am now handing over to Raman Goraya to guide you through the next session of Day 13. Goodnight.
1:27am: GOAL at the hockey! The Kookaburras have retaken the lead with 27 minutes left, after Glenn Turner bundled the ball home after about the sixth rebound of a ferocious Australian attack. Game on!
1:21am: The second half is under way in the men's hockey semi-final between Australia and Germany. It's still 1-1, with just over half an hour left.
1:18am: For those keeping score, the British team have won their 23rd gold medal of the Olympics, through Charlotte Dujardin's victory in the individual dressage competition. Together with team-mate's Laura Bechtolsheimer's bronze medal, Britain has now reached the half-century mark in overall medals.
1:14am: Australia's Sam Willoughby has missed out on automatic qualification, and will have to compete in the final two races of his quarter-final to confirm qualification.
1:08am: It's half-time at the hockey, and it's one goal apiece after Germany equalised in the 27th minute from a penalty corner.
1:05am: ABC's Karen Barlow is in Weymouth, and has tweeted that the women's elliott 6m races, which were scheduled for before the men's 470 class medal race, have now been called off for the day. That doesn't sound good for the medal race.
1:01am: Amazing escape from Khalen Young at the BMX! In the third heat of his semi-final, a New Zealand rider had a horrible crash, causing collateral damage in the field. Young jumped in mid-air, and bounced off one of the crashed rider's bikes before landing safely and went on to finish third. That's good going.
12:58am: The Kookaburras have taken the lead against Germany with a goal by Kieran Govers!
12:56am: Australia's synchronised swimming team has placed eighth after the technical routines with a score of 77.500. Russia is in first place with a brilliant 98.100 followed by China and Spain. The eight teams compete in their free routine on Day 14, with the two scores combined to decide the medallists.
"It felt good. It's hard to say until we've watched our video," said team member Eloise Amberger, who also competed in the duets.
"The scores don't really give us much indication. They are being quite low (during the) Olympics, and we received low scores in the duet as well so if we had a good swim then we're happy with that, the scores don't mean much to us."
"It's going to be hard for us to get to sixth, but we want to do our best and if we can get as close to Great Britain as we can then we will be very happy with that."
12:41am: The news is definitely improving at the BMX, with Sam Willoughby winning the second race of his quarter-final, putting him in reach of an automatic spot in the semi-finals.
12:39am: Victor Conte, the convicted owner of the BALCO laboratory that was at the centre of a global steroid scandal, says the drug-testing regime at the Olympics is irrelevant.
12:35am: Better news for Khalen Young in the second race of his BMX quarter-final. He came second, leaving him in third overall. He is within reach of an automatic advance to the semi-finals if he can make the top two after the third race.
12:32am: We are under way at the Riverbank Arena for the Kookaburra's men's hockey semi-final against Germany. No score yet after two minutes.
12:28am: Australia's chef de mission Nick Green has said that Sally Pearson, Anna Meares and sailor Malcolm Page - who still hasn't got off the start line in his men's 470 medal race - are among the leading contenders to carry the flag in the closing ceremony. ABC's Olympics reporter Matt Wordsworth
12:20am: An update and apologies regarding the women's football. It was of course the bronze medal match between Canada and France, not the semi-final. After 90 minutes of deadlocked football, Diana Matheson was the heroine for Canada, grabbing the winner in the second minute of added time. Heartbreak for France, a bronze medal for the Canadians.
12:14am: Not good in the fourth heat either - Australia's Brian Kirkham was caught out in a crash and finished seventh, while world champion Sam Willoughby flew too high on a jump and went from first to third, before being pipped on the line and finishing fourth.
12:12am: In case that first stack wasn't warning enough, the third quarter-final started with a big bang - France's Joris Daudet went down at the end of the first corner, and took out the rest of the field like ninepins - all except New Zealand's Marc Willers, who was in front at the time and missed the carnage.
12:06am: One race into the BMX quarter-finals and we've had our first stack. Unfortunately it was an Australian rider who went down. Khalen Young was in second position when he fell heavily and failed to finish. There are four more races in his quarter-final for him to score well enough to qualify, but it's not a nice start. Still to race their first race are Australia's Sam Willoughby and Brian Kirkham.
11.56pm: Day one of the individual all-around competition in rhythmic gymnastics is over, with two of the four rotations completed. The 24 competitors did ball and hoop routines on day one, with the ribbon and clubs to be completed tomorrow.
Australia's Janine Murray scored 24.350 on hoop and 23.100 on ball for a total of 47.450 points. She finished day one in 24th position.
11.40pm: Confirmation of a big change in the 4x400m relay ... South Africa are back in for the final, despite failing to finish their heat. Second leg runner Ofentse Mogawane tangled with Kenya's Vincent Kiilu and fell at the top of the home straight, dislocating his shoulder. Kenya finished the race, but were disqualified, prompting a South African appeal. More from the IAAF's official twitter account:
IAAF.org South Africa have been advanced to the 4x400m final after being obstructed in the heats.
This means that the Blade Runner, Oscar Pistorius, will get to run in the Olympic final. Here is his reaction on Twitter:
Oscar Pistorius IT'S ON!! We in the FINAL. Team management Protested as Ofense was taken out and we have been given Lane 9!! @ljvanzyl to take his place!!!
Will be up on the 3rd leg tomorrow for the Final! Really can't wait!
11:13pm: An update on the women's football - it is still goal-less between Canada and France after 56 minutes. Will someone find a way to break the deadlock, or are we going to go to extra-time?
11:07pm: What an amazing finish in the marathon swimming, with only 0.4 seconds difference between Hungary's Eva Risztov and American Haley Anderson at the end of 10km in the water. Risztov took the gold, Anderson the silver and Italy's Martina Grimaldi the bronze. Melissa Gorman was back in the second group, but her 11th place finish was a big improvement on her 15th placing in Beijing. Well done, Melissa.
10:48pm: With about 1km to go in the 10km marathon swimming, Melissa Gorman is in still in sixth position, but she is on the wrong side of a split in the field. The top five, who will likely fight out the medals, include long-time leader Eva Risztov of Hungary, American Haley Anderson, and home-town favourite Keri-anne Payne of Britain.
10.41pm: Wow. Just wow. the latest word from the men's 4x400m relay is that South Africa, who did not even finish their heat, will run in the final after an appeal. Here's the news from the BBC on Twitter:
BBC Sport "Blade runner" Oscar Pistorius to race in Friday's 4x400m final after all. South Africa through as appeal rules they were impeded in heat.
Not so sure we've heard the last of the appeals, somehow.
10.28pm: The first semi-final is underway in women's football, with Canada and France still goal-less after 25 minutes. The winner will play the United States or Japan in the gold medal game.
10.24pm: Melissa Gorman is doing well in the 10km marathon swimming event at Hyde Park. We may have got ahead of ourselves - the latest time mark is for the end of lap four, and Gorman has pushed up into sixth position, in a time of one hour, 19 minutes 03.7 seconds, five seconds back on leader Eva Risztov of Hungary, but now only 2.5 seconds back from America's Haley Anderson in third. The Australian seems to be positioning herself for a final challenge for the medals. We'll let you know as things develop.
10:06pm: Things are getting interesting at Hyde Park for the women's 10km marathon swimming event. With one lap to go, Melissa Gorman is in 11th position, 7.8 seconds back from the leader, Hungary's Eva Risztov. She is only five seconds off the bronze medal position of American Haley Anderson with 2.5km to go.
9:55pm: Sad news from the track, with the announcement that Jamaica's Asafa Powell is out of the men's 4x100m relay. The former 100m world record-holder picked up a groin strain in the final of the blue-riband event earlier this week. Powell's injury is serious enough to rule him out for the rest of the season.
9:49pm: We are half-way through the women's 10km marathon swimming at Hyde Park, and Melissa Gorman is in sixth place after two laps out of four, 4.2 seconds out of first placed swimmer. It's all to play for with five kilometres to go. Watch this space.
9:31pm: An update from the sailing - sadly, officials have delayed the men's 470 medal race at Weymouth and Portland due to a lack of wind. We don't know yet how long the delay will be, but in the meantime, here is a quote or two from British sailor Stuart Bithell, who with partner Luke Patience is hoping to deny Australia a seventh gold medal for the Games:
"It's theirs (Belcher and Page's) to lose; we are in the zone.
"They've a huge amount of talent between them. But me and Luke are the closest team and they know that."
9:22pm: After about 20 minutes of the women's 10km marathon swim, Australia's Melissa Gorman has surged to the front. It's early days yet but it's a good start.
9:12pm: There have been some delays in the early events at the sailing at Weymouth and Portland, but we are less than an hour away from the scheduled start of the medal race in the men's 470 class. Australia's Mathew Belcher and Malcolm Page can control their own destiny with the gold medal - if they beat the British pair of Luke Patience and Stuart Bithell, they will win the Olympic title. Belcher is sounding confident ahead of the race:
"We couldn't be in a better position. We deserve to win and we are ready."
9:03pm: Things are still in flux at the 4x400m relay, but Australia seem to have run into the Richmond position, finishing ninth. The two fastest losers' spots in the final went to Belgium (three minutes 01.70 seconds) and Poland (3:02.86) - Australia's 3:03.17 missing out by just .31 of a second. Bad luck, guys.
8:55pm: Well that was a bit of roller derby at the Olympic Stadium! Australia were in good position coming to the end of the second leg, but suddenly a scrum of runners at the hand-over point left Australia back in seventh or eighth from third. Brendan Cole ran a strong third leg, handing over to John Steffensen in fifth place, but he could not make up enough ground, and eventually faded to finish sixth. Australia finished in a time of three minutes 03.17 seconds, insufficient to qualify for the final.
8:43pm: Chaos in heat one of the relay, with South Africa's second runner clipping heels and falling on the track, injuring his shoulder, leaving the Blade Runner, Oscar Pistorius, stranded waiting for a baton change that would never arrive.
8:38pm: Good news at the diving, where Melissa Wu and Brittany Broben have both qualified for the final of the 10m platform event. Wu finished on 355.60 points after her five-dive program, with 16-year-old Broben showing nerves of steel to 359.55 points. Broben ranked third and Wu fourth, with both divers right in the mix for medals later tonight. China's Ruolin Chen is on course for an easy victory, leading the field by nearly 50 points after the semi. The final will be held at 4:00am (AEST).
8:28pm: Coming up shortly we will have the heats of the men's 4x400m relay at the Olympic Stadium. Australia will be in lane four of heat two, with the United States, the Bahamas and Japan the other main chances in that heat. The race will finally give John Steffensen a chance to do his talking on the track, after his claims that officials had discriminated against him by choosing Steve Solomon ahead of him for the individual 400m event. Solomon's qualification for the Olympic final at the age of 19 suggests they made the right decision. Let's hope for a good run by the team, with no baton problems.
8:09pm: The London organising committee has issued an explanation why Australia's Olympic champion hurdler Sally Pearson had her medal ceremony bumped yesterday. Apparently LOCOG wanted coverage to stay on the women's long jump competition, which was in its final stages:
"It was therefore decided by the sports presentation management at the Olympic Stadium that this live action should continue. The medal ceremony for the 100m hurdles was moved to the next available slot in the schedule."
“The medal ceremony took place that evening about 30 minutes later than scheduled.”
8:00pm: Earlier, a pair of 17-year-old schoolboys from Brisbane came third in the B Final of the C2 1000m event at Eton Dorney. Jake Haas and Jake Donaghey have had a big Olympics, and now are set for a big four years of development leading into Rio de Janeiro in 2016. Donaghey has spoken after the race:
"In the heat and the semi there was maybe some things we could have done better but that's what this is about. We're only 17 and it's all about learning and getting ready for 2016. This race was a massive improvement on what we did two days ago.
"It's the best experience I've ever had. Anyone can do it, just get outside with your mates - and anything can happen."
7:53pm: Australia's newest gold medallists, the men's kayak four crew have spoken after winning the K4 1000 final. Tate Smith has described the race as "perfect", and given the result it's hard to disagree:
"We had our best (form), we knew we would be right up there and it was just awesome from the start. We just dug deep and brought it home. It was just perfect.
"We've been able to put four good guys together. We were close in Beijing, and were really close in K4s, but we have just worked really hard - it's been our focus and our priority.
"We knew we could do it. We had this belief for the last three years and it's the biggest race of our life. It's unbelievable."
7:29pm: In diving, Australia's Melissa Wu and Brittany Broben have had a good start to the 10m platform semi-final. Wu is equal second after the first round - her forward 3.5 somersault dive in the pike position picked up 73.50 points, equal with America's Katie Bell, and gold medal favourite Ruolin Chen of China. Broben - competing in her first Olympics, lies in sixth after her first dive, a reverse 2.5 somersault in the tuck position, which received 71.55 points.
7:13pm: That victory gives Australia a sixth gold medal for the Olympics, which puts the team ninth on the gold medal tally behind Italy on seven gold medals and France on eight.
7:07pm: Nothing like a bit of excitement to start the day off, is there? Check out our story on the men's K4 1000 .
7:00pm: The Australians led from start to finish, stopping the clock in two minutes 55.085 seconds, ahead of Hungary (2:55.699) and Czech Republic (2:55.850).
6:58pm: GOLD MEDAL TO AUSTRALIA!!! "That's awesome, I've got chills," says their team-mate Ken Wallace on Grandstand, and who would disagree with him.
6:56pm: Australia still in front, Hungary in second, here comes Germany, Slovakia going fast ... here comes the line, and the Aussies win! What a great performance by Tate Smith, Dave Smith, Murray Stewart and Jacob Clear!
6:53pm: Australia leading early, but you could throw a blanket over most of them!
6:51pm: A correction ... the Germans are in lane six, it was the Hungarians in lane four who made the false start. One more and they are out.
6:49pm: And there's a false start! That's the last thing anyone needs ...
6:47pm: They are a bit behind schedule at Eton Dorney, but here we go for the K4 1000 final, with the Australian team in lane three, right next to their main competition, the Germans in lane four.
6:36pm: Brisbane pair Alex Haas and Jake Donaghey have come third in the B Final of the men's canoe double (C2) 1000m. The Australians finished behind Poland and Brazil.
6:33pm: We are about five minutes away from the gold medal race in the men's kayak four (K4) 1000m event. Tate Smith, Dave Smith, Murray Stewart and Jacob Clear qualified fastest for the final ahead of Germany and the Czech Republic. The question is how much is left in the tank for the Australians and their rivals.
6:29pm: That was a surprise - American Trey Hardee beat the world record-holder Ashton Eaton - just - by 13.54 seconds to 13.56. That keeps Hardee in the hunt for a gold medal, while Eaton, who only broke the world record in the lead-up to London, will need to lift in the remaining events.
6:23pm: The action is already under way at the Olympic Stadium, with the sixth event of the decathlon, the 110m hurdles. American Ashton Eaton leads the field with 4661 points after five events, a 220-point lead over his team-mate Trey Hardee. Eaton, Hardee and Canada's Damian Warner (in third place overall) are all in heat four coming up.
6:17pm: In the early hours of Friday morning, Australia's women's water polo team will take to the pool for their final match in London. The Stingers lost their semi-final to their old rivals, the United States. Now they face Hungary for the bronze medal. As always, no quarter will be given.
6:13pm: Sam Willoughby, Khalen Young and Brian Kirkham will all take part in the quarter-finals of the men's BMX competition from midnight (AEST). The quarter-finals are held over five races, with points awarded for each run. After three runs, the best two riders from each quarter-final will go through to the semis, with the remaining riders going in the last two rides for two more spots in the semi-finals. It will be chaotic, and spills are likely. Best of luck to all three Australian riders.
6:06pm: Spare a thought for Australia's Melissa Gorman, who has sat through week one of the Olympics watching the rest of the swim team compete while waiting for her event to come up. From 9:00pm (AEST) at London's Hyde Park, Gorman will finally take to the water in the women's 10km marathon race. The Queenslander came 15th in the 10km open water race in Beijing.
6:01pm: If you happen to be tuned in to the first-ever Olympic finals in women's boxing tonight, pack some ear-plugs. At 1:45am (AEST), Ireland's Katie Taylor will be up against Russia's Sofya Ochigava in the final of the 60kg division. The Irish-dominated crowd registered 113.7 decibels in the ExCeL Arena for Taylor's first-round bout, the loudest single event of the Olympics. If the Irish boxer adds gold to her four world titles, they'll hear the crowd's reaction back in Dublin!
5:56pm: One of the biggest moments of Day 13 will come at 10:00pm (AEST) at Weymouth and Portland, when Australians Mathew Belcher and Malcolm Page take to the waters for the medal race in the men's 470 sailing class. The Aussies are four points clear of their nearest rivals, Luke Patience and Stuart Bithell of Great Britain. If they can keep ahead of the British, it doesn't matter where they finish, the gold will be theirs. Should be a dramatic race. Don't miss it.
5:51pm: In hockey, it's crunch time for the Kookaburras who face the defending Olympic champions Germany in the semi-finals at 12:30am (AEST). Australia will need every bit of attacking drive that five-time world player of the year, Jamie Dwyer, can muster to get past the Germans. The winner will play the Netherlands or Great Britain for the gold medal.
5:47pm: On Day 12, the Boomers put up a brilliant fight against the U.S. Dream Team, staying within five points late in the third quarter until the favourites pulled away. At 2:00am (AEST) on Friday, it's the turn of the Opals to face the mighty American team, with a spot in the gold medal match up for grabs. Australia will need big games from the likes of Liz Cambage and Lauren Jackson, but an upset is not out of the question. It should be a cracker of a game.
5:35pm: Welcome back to Grandstand's live coverage of the London Olympics. Just over an hour from now the Aussie men's kayak four (Tate Smith, Dave Smith, Murray Stewart and Jacob Clear) will try to seal gold number six for the green and gold.
