Relive Grandstand's live coverage of Day Eight of the London Olympics, including updates on all the Australians.
9:10am: And that's a wrap for yet another busy day of Olympic Games action. If you happened to sleep in this Sunday morning, be sure to catch up with everything by scrolling down through our live coverage. We'll be back tomorrow to do it all again on Day Nine. See you then.
9.00am: The gold drought continues for the Aussies after Day Eight, but we managed to add to our world-famous silver tally thanks to the women's 4x100m medley relay, the men's fours rowing and long jumper Mitchell Watt. Single sculler Kim Crow, triathlete Erin Densham and the men's 4x100m medley relay also added bronze medals to take our total to 1-12-7 (20). Just quietly, Australia is not alone. Russia has 15 silver medals and just three golds. Most definitely down on their usual lofty standards. In contrast, Great Britain enjoyed a sparkling day of six gold medals and one silver across the rowing, cycling and track and field to be outright third after eight days with a return of 14-7-8 (29).
8:50am: The lights are turned off and the curtain falls on the action from the Olympic pool. Might be a rave later on Melanie Schlanger?
Thanks to everyone for the amazing support this week! I have had an absolute ball and enjoyed every minute! Now it's party time!! :)
7.45am: Kazakhstan's captured a fifth gold medal when Ilya Ilyin set two new world records to win the under-94kg men's weightlifting. The 24-year-old's total of 418kg beat the old mark of 412kg as well as setting a new world mark with a lift of 233kg in the clean and jerk. What's his secret you ask? Horse meat.
"I try not to eat anything that is too fat or sweet. My favourite food is chicken and horse meat. I would consider them ideal food because they are very easy to digest.
"You don't waste any personal energy and you don't have to digest difficult things like lamb or pork.
"Chicken and horse meat are the best foods for weightlifters and good food is important."
7.40am: Earlier in the morning, Two-time European champion Sandra Perkovic won the women's discus final. The 22-year-old Croat, who served a six-month doping ban in 2011, threw a best of 69.11 metres, a national record, with Russia's Darya Pischalnikova claiming silver with 67.56m, and China's Li Yanfeng taking bronze (67.22). Aussie Dani Samuels did not make the top eight.
7.30am: Australian Jeff Horn progresses to the quarter-finals of the men's light welter with an impressive 17-11 victory over Tunisian Abderrazak Houya. Horn's first and second rounds laid the platform for the win as he flies the Aussie flag in the ring.
"My tactic is to stay relaxed. I could not think of a better feeling. I could have done better out there but a win is a win. It feels awesome and I'm proud to make it here."
"I can improve on everything without a doubt. A medal would be a dream come true. It would be great to do it for my country and my family.
"I can go all the way. I try not to let it bother me and I think I perform better under pressure.
"It has been 24 years since our last medal and I'm 24, so that's saying something."
7.17am: Normal service has resumed somewhat. Even after Great Britain's most memorable day in Olympics history, they still find a way to bottle it in a shoot-out. The Brits are eliminated in the quarter-finals after a 5-4 loss on penalties to South Korea, after scores were level 1-1 at full-time and at the end of extra-time. Chelsea's Daniel Sturridge (he's English by the way) was the man left red-faced. In other results, Japan defeated Egypt 3-0, Mexico downed Senegal 4-2 and favourites Brazil progressed with a 3-2 victory over Honduras. Mexico will face Japan while Brazil meets South Korea in the semis.
6.55am: Shelley-Anne Fraser-Pryce defends her women's 100m title with victory in London. The Jamaican ran 10.75 to become the first woman to go back-to-back in the event since American in 1992-1996. Carmelita Jeter of the USA finished in 10.78 to take silver and Jamaican Veronica Campbell-Brown takes the bronze in 10.81.
6.54am: The Boomers come from behind to defeat winless Great Britain 106-75 and setup a likely quarter-final clash with the dominant USA. Patty Mills starred with 39 points. Can't win them all eh, GB. Got to take the small victories right now.
"I think we pride ourselves on being the fittest team here and defensively being tough," Mills said of Australia's fight-back.
"I think we put those together and at the end of the game we just had more legs."
6.46am: Mo Farah makes it a GB hat-trick of golds at the Olympic Stadium with a thrilling triumph in the men's 10,000 metres. What a night to remember for the hosts. First Ennis, then Rutherford and now Farah, who carried Cathy Freeman-like expectations on his back. An emotional moment for the Somalian-born athlete. The Brits are in dreamland - six golds and a silver on day eight for a total of 14 golds, seven silver and eight bronze, behind only US and China. Super Saturday indeed.
Meanwhile, ABC reporter Matt Wordsworth is doing it tough at the stadium:
: Brit just sledged me telling me there are more Yorkshiremen with golds than Australians. I had no comeback.
6.30am: All the focus was on Watt, but there has been some strange goings on out at the Basketball Arena. The Boomers were trailing Great Britain by 15 and then produced a 30-14 third quarter and are going on with the job in the final. Patty Mills absolutely balling.
6.23am: Mitchell Watt hangs on for silver in the long jump. Great Britain's Greg Rutherford wins the hosts' second gold in as many minutes after Jess Ennis. It's an upset, but I guess redheads can jump. Actually, Rutherford's 8.31 is the shortest winning leap in the long jump since Randy Williams in Munich '72 (8.24). Watt had Rutherford's measure this season, but not on this night. His face tells the story - Mega Watt ain't happy. Rutherford's face looks a bit like Neil Patrick Harris - we were all thinking it. Watt joins fellow Aussies Bill Bruce (1948) Gary Honey (1984) and Jai Taurima (2000) to claim silver in this event. Australia has never won the . The wait for more gold continues.
Despite his disappointment, Watt could still find time for a laugh at his expense.
"My best jump was when Jessica Ennis was going past," he said.
"So I just pretended I was British for about 30 seconds."
6.14am: Watt improves to 8.16m with his final leap, but he can't overhaul Rutherford. He's in line for silver - go figure. The Aussie just didn't look comfortable in his approach and his season's best of 8.28 was never threatened. Now we play the waiting game. Three jumpers can steal Mitchell's silver medal away.
6.04am: Mega Watt is into second! He finally hits the board with a bit of authority and posts a 8.13. Can he wind up and steal a gold medal with his sixth and final jump?
6.02am: If there wasn't enough noise in this joint, Great Britain's face of the Games, Jess Ennis, has just stormed to gold in the women's heptathlon with a stirring win in the 800 metres. Union Jacks everywhere. If you missed it, there will be replays for the rest of the decade.
5.58am: Wow. Home favourite Greg Rutherford launches into the back of the pit with a 8.31, 4cm off the British record. Into a head wind. That is going to be very tough to beat. Watt fouled his fourth jump. The Aussie needs to find something if he wants to silence this crowd.
5.47am: Mitchell Watt is through to the final eight in the men's long jump. The Aussie progressed with a 7.97 but has so far struggled to find his rhythm on the runway. Compatriot Henry Frayne agonisingly missed out by eight centimetres. Rutherford still holds the best jump at 8.21.
5.41am: The United States men's 4x100 medley team helps Michael Phelps to his 18th Olympic gold medal, a fitting Games farewell for the phenom of the pool. Australia's team of Stoeckel, Sprenger, Targett and Magnussen takes the bronze behind a brave Japan, which was inspired by a great breaststroke leg by veteran Kosuke Kitajima.
5.20am: Great Britain's Greg Rutherford has landed a 8.21 with his second attempt in the long jump. Mitchell Watt is fourth after two jumps with a 7.97. Frayne fouled his second attempt. Four more jumps to go.
5.18am: United States cruises to victory in the women's 4x100m medley relay ahead of Australia in a world record time of 3:57.05. Japan third. A totally dominant display by the Americans and a courageous performance by the Aussie girls. Melanie Schlanger was brilliant again with the freestyle anchor leg. So too was Alicia Coutts, who now has five medals, with a stirring butterfly leg after the retiring Leisel Jones lost contact during the breaststroke. Australia now has 11 silver medals, six bronze, one gold.
5.01am: Henry Frayne and Mitchell Watt with their first attempts in the men's long jump final. The Frayne Train/Plane (have they decided yet?) lays down a decent marker with a jump of 7.85. Watt pulled out of his first attempt.
5.00am: Dani Samuels is out of the women's discus final, failing to make the top eight. The Australia's final throw was her worst at 57.87. A disappointing start to Australia's track and field campaign.
4.58am: Sun Jung of China has just demolished his own 1,500m freestyle record with a time of 14:31.02 to take his second gold of the Games. His nearest rival, Canada's Ryan Cochrane, was eight seconds further back. Defending champion Oussama Mellouli took bronze.
4.51am: On the track, America's world champion Carmelita Jeter qualified fastest for the women's 100 metres final ahead of Shelly-Ann Fraser-Pryce, Veronica Campbell-Brown and Nigerian Blessing Okagbare. Silver medallist from Beijing, Kerron Stewart missed the final.
4.45am: At the track and field, Australian Dani Samuels registers throws of 60.40 and 59.86 in the first stages of the women's discus final. She'll need a big final effort to progress.
4.40am: DRAMA! Chinese champion Sun Jang appears to have false started in the final of the men's 1,500m final. He leapt off the blocks like somebody tried to brand him. This happened earlier in the week to Breeja Larson in the 100m breaststroke. Not sure the start is all that crucial in a 1,500m race. All appears OK, though. Sun has been allowed to swim and dives in with his competitors. Crowd noise may have been the culprit this time.
4.35am: Double Dutch delight for Ranomi Kromowidjojo (can spell that in my sleep now) as she adds the 50m freestyle to her 100m title from earlier in the week. The sprint queen wins in an Olympic record time of 24.05. Silver for Belarusian Aliaksandra Herasimenia and bronze to Marleen Veldhuis of the Netherlands.
4.30am: Going to be a real juggling act between the final night at the pool and the second night of action at the Olympic Stadium. The women are lining up for the 50m freestyle splash and dash now. At the same time the women's 100m semi-finals are on the track. We'll try and keep up.
4.26am: Australia need a gold. Badly. Tom Slingsby could be the man to deliver in the Laser sailing class. He holds a tidy lead going into Tuesday (AEST) medal race. But, thankfully, he is determined not to get complacent.
4.15am: Gerard Whateley has the Australian teams for tonight's medley relays. In the women's: Seebohm, Jones, Coutts, and Schlanger will take on US golden quartet Franklin, Soni, Vollmer, Schmitt. In the men's: Stoeckel, Sprengher, Targett and Magnussen take Grevers, Hansen, Phelps and Adrian of the USA.
4.15am: Australian Tristan Thomas finished eighth in the second semi-final of the men's 400m hurdles in 50.55 seconds. Great Britain's David Green, one of the favourites, also failed to qualify for the final after finishing fourth in the first semi. Felix Sanchez, Olympics champion in Athens, qualified fastest in 47.76.
3.55am: A good result for Glenn O'Shea in the elimination race. He picked up three points (the less points the better) after being the third last rider eliminated. France's Bryan Coquard won the race and leads the overall competition on 10 points. Italian Elia Viviani is second on 13, while O'Shea is well placed in third on 14 points. Tomorrow the riders take on the 4km individual pursuit, 15km scratch race and the 1km time trial in the race for omnium gold.
3.37am: Everything really is going well for Team GB after a slow start. They're singing Hey Jude with McCartney at the Velodrome. Meanwhile, the elimination race is about to get going in the men's omnium.
3.20am: Jared Tallent has finished seventh in the men's 20km walk. The Aussie was up with the lead pack but could not match the pace of the big players in the back end of the race. China's Ding Chen claimed gold ahead of Guatemala's Erick Barrondo with China's Zhen Wang third.
3.10am: Australia has missed out in the ride-off for bronze in the women's team pursuit, beaten by Canada. No surprises who took the gold - Great Britain. They now have five golds on the tack and captured this one in a world record time of 3:14:051 over United States. Even Paul McCartney is joining in the rock-concert like festivities at the Velodrome.
2.43am: Aussie Jared Tallent has moved up to seventh just past the halfway mark of the men's 20km walk.
2.40am: German Roger Kluge has won the points race in the men's omnium. Kluge lapped the field three times for 60 points and picked up another 19 in sprint points. Dane Lasse Norman Hansen (59) was second and Spain's Eloy Teruel Rovira (55). Glen O'Shea was eighth (25). So after two events, Hansen leads from Frenchman Bryan Cogquard with O'Shea in third. The boys will be back for the exciting elimination race later today.
2.30am: The star-studded United States has picked up another win in the group stage, but did not have it all its own way against Lithuania. The plucky underdogs, who have won one match, trailed the US by just four points at half-time and ended up going down 99-94 in a courageous display. Lebron James was the star with 20 points, sparking a 12-2 run that banked the result for the US. Carmelo Antony also had 20 points while Lithuanian Linas Kleiza led all scorers with 25.
2.23am: Glenn O'Shea is off to a good start in the 30km points race, part of the men's omnium. The Aussie is fourth on 25 points in the early stages.
2.15am: Aussie Damien Hooper is out of the light heavy division in the round of 16. Hooper ran into Russian Egor Mekhontcev, who used his experience to dish out a 19-11 victory. No shame for the 20-year-old Hooper, all part of the learning experience. But his coach Don Abnett was not as pleased:
"Damien didn't show up today," Abnett said.
"Damien is like that. It's just the pressure of here and the boy's reputation affected him.
"He just didn't land the blows. He got caught at mid-range and didn't use his leg movements like I wanted him to. He had to go for it in the last round."
2.10am: They're off and... walking... in the 20km walk, starting at The Mall. Thousands of fans out and about in London catching a (free) glimpse of this event. Aussies to watch out for are Jared Tallent, Chris Erickson and Adam Rutter. The world record is one hour 17 minutes and 16 seconds.
2.05am: Unfortunately, the Australian men's team has gone down to Italy in a five-set thriller at Earls Court. The Volleyroos took the opening two sets 25-21, 25-18 against the medal contending Italians. But the favourites finally found their range, producing some top volleyball to win the next three sets 25-21, 25-14, 15-13. The loss means Australia cannot make it out of the group stage, with one win from four matches. The Volleyroos take on Poland in their final match in two days.
2.00am: A bleary-eyed Raman Goraya to take you through to the morning. Happy to be here, folks. News from the Velodrome is Aussie Shane Perkins is through to the quarter-finals of the men's sprint. Perkins' opponent, Venezuelan Hersony Canelon, was relegated handing the Australian a berth in the final eight this time tomorrow.
1.32am: We've had a heart-breaker at the Velodrome, where Australia has been beaten by the United States in the women's team pursuit semi-finals. Australia took off at world record pace, and led comfortably for most of the race, but they began to tire as the American trip made their move. The Australians led by 0.112 of a second with one lap to go, but the Americans finished faster to win on the line. The Australians will now ride off for bronze.
1.22am: We are just over three hours away from the final of the women's discus at the Olympic Stadium, where Australia's Dani Samuels will challenge for the medals. To see some stats on the event,
1.19am: It's getting closer at the men's volleyball. The Italian team lost the first two sets to Australia, but have rebounded to win the third set 25-21. The score is now 12-6 to Italy in the fourth set, so we could be heading to a decider.
1.12am: Another sailing update: Tom Slingsby has won both races in the men's laser class to go into the medal race in first place, with a lead of 14 points over his nearest rival, Cypriot sailor Pavlos Kontides. In the women's elliott 6m class, Australia's match-racing team has completed a perfect run, beating Portugal to sweep all 11 races. Australia now progresses to the knockout stage. In the men's 470, Mathew Belcher and Malcolm Page have won race five today, and have regained first place over the British crew.
1.00am: Australia will have two representatives in the final of the women's 3m springboard diving event. Sharleen Stratton finished ninth in the semi-final with a score of 327.60, while Jaele Patrick came 11th with a score of 315.60. As ever, China was the country to beat, with Wu Minxia qualifying in first place with a score of 394.40.
12.56am: Suzanne Balogh has come sixth in the final of the women's trap shooting event. The Australian, who won the title in Athens in 2004, shot 87 targets in the final, compared to 99 for the new champion, Italy's Jessica Rossi.
12.42am: There is a big upset in the offing at the men's volleyball, where the Australian team has taken a two sets to none lead against Italy. The Volleyroos won the first set 25-21, and have just added the second 25-18.
12.38am: Australian rowing legend Drew Ginn has spoken after his silver medal performance in the men's four final at Eton Dorney. Ginn now has three gold medals and a silver from four Olympics, an amazing achievement:
Full credit to the GB four for going out the way they did. We felt if we stuck to those guys we could get to the finish first. It's not the result we came here for but we can walk away with our heads held high.
They (his team-mates) have a huge future ahead of them. What they have managed to do is incredible. They have never shirked from any challenge.
For me at 37, I would love to go on but it takes a lot and that's what you see, everyone gives their everything. You dig deep but it takes a toll on your body and on your family.
I will make no brash statements but the reality is I have had two back surgeries and after Beijing I never thought I'd make it back.
12.25am: The United States' Serena Williams has won her first Olympic gold medal, blitzing Russia's Russia's Maria Sharapova in the women's singles 6-0, 6-1. Williams sealed the win with an ace in a match that lasted just 62 minutes.
12.20am: ABC's Olympics reporter Matt Wordsworth has filed a story on Saint Kitts and Nevis sprinter Kim Collins' absence from the 100m heats.
12.13am: Some quotes from Lleyton Hewitt after he and Samantha Stosur bowed out of the mixed doubles tennis against Britain's Andy Murray and Laura Robson:
That's mixed doubles. We've lost by two points, 10-8 in a super buster. Mixed doubles can go either way. There's only one or two points here or there. It depends on who's serving sometimes towards the end of a big tie-break like that and we couldn't get over the line.
Asked whether this was his last chance at an Olympic medal, Hewitt replied:
I don't know. We'll have to wait and see.
12.07am: A result from earlier in the men's water polo - Australia lost 11-6 to the unbeaten Croatian side. The Sharks will finish the pool matches against Greece.
11.43pm: We knew the women's triathlon finish was close, but here is confirmation ... Switzerland's Nicola Spirig and Sweden's Lisa Norden finished on the same time, one hour 59 minutes 48 seconds but Spirig was awarded the gold medal after a photo finish. Now judges have confirmed that the gap between the pair was less than 15 centimetres. At the end of a triathlon, that is just crazy!
11.37pm: An update on the sailing regatta at Weymouth and Portland - Australia's Tom Slingsby has extended his lead in the men's laser class after he won race nine. The final fleet race is underway, with Slingsby a strong gold medal chance in Monday's medal race. Jessica Crisp has had two good races in the RS-X class, coming fifth and eighth. She sits in 11th overall, however, and is unlikely to challenge for medals.
11.18pm: At the track cycling, Shane Perkins has tried for a bit of psychological advantage over British men's sprint favourite Jason Kenny - who set an Olympic record time in his opening race - after the Australian sealed his spot in the next round:
I'm happy with the qualifying. I'm in under ten (seconds) I'm really happy with that. The times in my training were quicker and, hopefully, I'm doing Australia proud by getting into the next round.
With the Olympic record the pressure is on him (Kenny) now.
11.08pm: More quotes, this time from the defending 100m champion, Usain Bolt, after his training jog in the heats:
I expected it (the heat win), I'm running well, I'm happy, training is great. Reaction was good.
I'm looking forward to the semi-finals tomorrow.
I made a bad step (at the start). I stumbled a bit. I'm glad it happened now.
11.00pm: Australia's Kim Crow has spoken after winning her second medal of the games, a bronze in the women's single scull:
I think it'll take a little while to sink in. That was all I had.
I felt really bad for all the guys who came out when it was bucketing down. I couldn't help but think I had the easy job.
10.51pm: Mixed fortunes in the women's pole vault for Australia - Alana Boyd has qualified for the final, with a clearance on her second attempt at 4.55m. However Liz Parnov has failed to register a height, after missing three times at her opening height of 4.10m.
10.42pm: It's all over in the tennis! Lleyton Hewitt and Samantha Stosur lost the first set against Britain's Andy Murray and Laura Robson 6-3, but they levelled the match with an identical score in the second set. It came down to a super-set, with the British pair winning 10 points to eight.
10.35pm: Australian shooter Suzanne Balogh - who won the women's single trap in Athens but missed selection in Beijing - has qualified for the final in London. Balogh shot 72 out of 75 for third in qualifying, but she will have her work cut out in the final to get past Italy's Jessica Rossi, who broke the world record by shooting a perfect 75 targets out of 75!
10.30pm: Good news in equestrian - Australia's Edwina Tops-Alexander has had a clear round in qualifying for the individual jumping competition on her horse Itot du Chateau. Tops-Alexander is the highest-ranked female rider in the world, and a big chance for a medal in jumping at the Games.
10.25pm: British sprinter Dwain Chambers has won what would have been Collins' heat, in a time of 10.02 seconds. Chambers was only cleared to compete in the Olympics after a court decision overturning a life ban for doping.
10.18pm: Sensation on the track, as Saint Kitts and Nevis sprinter Kim Collins did not race in his heat. Reports suggest he was withdrawn from the event by his team after spending last night in a hotel with his wife rather than in the athlete's village!
10.12pm: World champion Yohan Blake was the next of the big names to run in the 100m, stopping the clock in 10 seconds dead. Blake has the psychological advantage over his countryman Bolt, having beaten him in the 100m and 200m at the Olympic trials.
10.06pm: Jamaican Asafa Powell - who was fifth in the 100m four years ago behind Bolt - has cruised to victory in his heat in 10.04 seconds. Adam Gemili, 18, from Britain has also qualified in 10.11 seconds.
9.57pm: That was a training run for Bolt! The Jamaican superstar's hamstring gave him big trouble ahead of the Games when he was beaten in the Olympic trials by Yohan Blake. He didn't look in any trouble there, easing down with 40m to go. Bolt clocked 10.09 seconds to win his heat.
9.53pm: It's time for Usain Bolt in the 100m ...
9.52pm: BRONZE MEDAL TO AUSTRALIA! Kim Crow has charged for the line at the end of the women's single scull, winning bronze just behind Denmark's Fie Udby Erichsen and a long way behind runaway winner Miroslava Knapcova of the Czech Republic.
9.50pm: American Ryan Bailey has run 9.88 seconds for the 100m in his heat at the Olympic Stadium.
9.46pm: In the women's single scull final, Australia's Kim Crow is up against Miroslava Knapcova of the Czech Republic. Knapcova leads by five seconds at half-way.
9.43pm: Justin Gatlin from the U.S. - who won the 100m in Athens eight years ago but could not defend his title in Beijing after being banned for doping - has started his campaign with a heat win in 9.97 seconds, well clear of the field.
9.33pm: It's time for the men's 100m at the Olympic Stadium. American Tyson Gay had a poor start in his heat but came through to win in 10.08 seconds. Up soon are Yohan Blake and Usain Bolt.
9.31pm: Australian track cyclist Glenn O'Shea is third after the flying lap, the first event of five in the men's omnium. He lies behind New Zealand's Shane Archibald and leader Britain's Edward Clancy.
9.22pm: At the track cycling, Australia's Shane Perkins has qualified for the quarter-finals of the men's sprint, beating Hodei Mazquiaran Uria of Spain to advance.
9.12pm: For a wrap of the action so far at the Olympic Stadium,
9.08pm: At Wimbledon, Samantha Stosur and Lleyton Hewitt are warming up for their mixed doubles quarter-final against Britain's Laura Robson and Andy Murray.
9.01pm: Time for another chorus of God Save the Queen ... Britain's Katherine Copeland and Sophie Hosking have won the gold medal in the lightweight double scull, from China and Greece, with the Australians back in fifth.
8.56pm: The Australian pair are rowing from the wind-affected lane two and are struggling to keep up with the pace of the British and Greek crews.
8.54pm: Back at Eton Dorney, Australia's Bronwen Watson and Hannah Every-Hall are in action in the final of the women's lightweight double scull.
8.50pm: LaCaze has finished seventh in her heat of the 3000m steeplechase, finishing in a time of nine minutes 37.90 seconds. She beat her personal best by four seconds, but it is unlikely to be enough to qualify her for the final.
8.43pm: At the Olympic Stadium, Australia's Genevieve LaCaze is making her debut in the women's 3000m steeplechase. LaCaze was the athlete who set an A qualifying time a day after the deadline before being added late to the Olympic team.
8.40pm: It's nearing half-time in the men's water polo match between Australia and Croatia. Croatia leads the Sharks 3-2.
8.38pm: SILVER MEDAL FOR AUSTRALIA! Britain first, Australia second, and the United States in third.
8.37pm: Australia is lifting in the final stages, but the British are hanging on ... and it's going to be four in a row for the home side!
8.35pm: The British are up slightly at half-way with the Australians in second and the United States in the bronze medal position. There is less than a canvas in it - it should be a big finish.
8.33pm: It's six minutes to glory for one crew at Eton Dorney, as Australia and Great Britain are set to battle it out for the gold medal in the men's four. Drew Ginn is going for his fourth gold medal in as many Games, while the British are trying to make it four Olympic title in a row in the four.
8.29pm: Drama at the Olympic Stadium, where defending champion LaShawn Merritt of the United States is out of the 400m. He failed to finish his heat, which was won by Australia's Steve Solomon in 45.18 seconds, a personal best.
8.06pm: Spirig and Norden both finished in a time of one hour 59 minutes, 48 seconds, with Erin Densham third in 1:59:50. Australia's Emma Jackson was eighth in 2:01:16.
8.04pm: BRONZE MEDAL FOR AUSTRALIA! A gusty effort by Erin Densham, who did most of the work at the front of the lead group in the run leg. She stayed clear to win the bronze medal, but could not match the finishing kick of the Swiss and Swedish triathletes.
8.02pm: What a finish, Densham faded for third in the final sprint, but it's an old-fashioned photo finish between Switzerland's Nicola Spirig and Sweden's Lisa Norden, who sprinted across the line with nothing between them.
8.00pm: The sprint is on, here comes Densham ...
7.58pm: Who has the finishing kick to win the triathlon title? It's going to be very tight.
7.56pm: The top four at the women's triathlon have been joined by American Sarah Groff, with a couple of kilometres to go. The British favourite Helen Jenkins may be the first one to crack and is dropping back seven or eight metres.
7.52pm: Earlier tonight, the Hockeyroos beat South Africa 1-0 at the Riverbank Arena.
7.49pm: It's cat and mouse at the front of the women's triathlon right now. On the third lap of four in the run leg, the lead group is down to four athletes, including Australia's Erin Densham and Britain's Helen Jenkins.
7.45pm: The domination continues for Britain at the Velodrome. In the men's sprint, Jason Kenny has set a new Olympic record of 9.713 seconds. France's Gregory Bauge was second-fastest in 9.952, and Australia's Shane Perkins was third in 9.987.
7.42pm: History has been made at the Olympic Stadium, as South Africa's Oscar Pistorius ran in the first heat of the men's 400m. There was a huge roar as the Blade Runner ran the one-lap event, finishing off down the main straight in second place in a time of 45.44 seconds, which qualifies him for tomorrow's semi-finals. Pistorius becomes the first athlete with prosthetic legs to compete at an Olympics. Well done, Oscar. A huge story at these Games.
7.36pm: The women are out for the run leg of the triathlon, and it is good news for Australia. Erin Densham is in the lead group in sixth spot, and Emma Jackson is in the lead group further back.
7.12pm: Things have started at the Velodrome, with the qualifying for the men's sprint. Australia will be represented by Shane Perkins, while Britain will have Jason Kenny on the track. Kenny caused controversy when he was picked for the sprint ahead of British great Chris Hoy. Such are the selection problems when every country has only one rider in the event.
7.08pm: ABC Grandstand's Julian Abbott has given a possible explanation for all the falls in the women's triathlon. He has said there are reports of diesel or oil on the road at Hyde Park Corner. That, coupled with the wet road conditions could be adding to the chaos on the bike leg. Erin Densham is the best placed Australian on lap five of the bike leg, sitting in 11th place in the main bunch. Britain's Lucy Hall is in fourth, and favourite Helen Jenkins is just ahead of Densham in ninth.
7.01pm: That was close! Australia defeats South Africa 1-0, but the South African team had a string of penalty corners which they couldn't convert. That is the Hockeyroos' third win from four games, thanks to Jade Close's shot from the top of the D after even minutes of play. Australia will play Argentina in the last of the pool games - that will not be easy.
6.50pm: The Hockeyroos are holding their 1-0 lead over South Africa at the hockey, but with 10 minutes to go, the South Africans are on the attack, and Australia is hanging on after Georgia Nanscawen was sent to the bench with a yellow card.
6.43pm: Bad news at the triathlon - there are reports that Australia's Emma Moffatt is out of the race. It appears that she may have been in a crash - a couple of riders have already gone down in nasty crashes on on slippery roads. Erin Densham is in touch in 20th position and Emma Jackson is also in striking distance in 22nd.
6.30pm: The leaders in the triathlon are on the bike leg, with five or six riders in the lead group, about a minute ahead of the three Australians, Emma Moffatt, Emma Jackson and Erin Densham. We have already had a bad crash, with Brazil's Pamella Oliveira - who was leading the race - falling hard and losing a lot of time. British triathlete Lucy Hall is giving the crowd something to shout about, as she is in the lead group at this early stage.
6.23pm: There is no morning session at the swimming today, with only one night session to come. There will be four finals on the program, starting at 4.30am AEST with the women's 50m freestyle and the men's 1500m freestyle final at 4.36am - neither will have Australians in the final field. The last two events on the program, however, do have Australians in the line-up. The Australians are the fastest qualifiers for the women's 4x100m medley relay final at 5.07am, but the United States team will be favoured to storm to victory with the additions of Rebecca Soni, Missy Franklin and Dana Vollmer. If Australia wins any medal, Leisel Jones will join Ian Thorpe as Australia's most successful Olympians with nine overall medals. The men's medley relay will finish the night at 5.27am. The United States are favoured to win, which would give Michael Phelps an amazing 18th gold medal in his final race before retirement.
6.12pm: It's half-time in the hockey, and the Hockeyroos are still 1-0 up on South Africa, thanks to Jade Close's seventh-minute goal. The Australians have had their chances to go further in front - hopefully they won't regret their wasteful shooting like the Kookaburras did last night.
6.09pm: To check out some stats about the women's triathlon event,
6.01pm: They are off in the women's triathlon, where Britain's Helen Jenkins will start favourite for the event. The defending champion, Australia's Emma Snowsill, was not selected for the Olympic team, and it will be down to the other two Emmas, Moffatt and Jackson, and Erin Densham, to try to keep the Olympic title Down Under tonight.
5.56pm: Australia have some medal hopes in the field tonight. Mitchell Watt qualified ninth and Henry Frayne 11th for the final of the men's long jump, which will start at 4.55am AEST. Commonwealth Games women's discus champion Dani Samuels was heading for a nearly exit from Olympic competition last night, before a last-round throw of 63.97m qualified her for the final, which will begin at 4.30am AEST.
5.49pm: There will be some great action around the Olympic venues tonight and tomorrow morning AEST. Starting with athletics, we will see the first glimpse of the world's fastest man, Jamaica's Usain Bolt, in the men's 100m preliminaries at 9.30pm AEST. The final of the women's 100m will be run at 6.55am Sunday AEST. Earlier, at 7.35pm AEST, the man they call the Blade Runner, South Africa's Oscar Pistorius, will become the first athlete with prosthetic legs to compete at an Olympics when he runs in the 400m.
5.40pm: Hello, I'm Andrew McGarry, and welcome to ABC Grandstand's live coverage of Day Eight of the London 2012 Olympics. We're already underway at the Riverbank Arena, where the Hockeyroos have taken the lead over South Africa after seven minutes of play through Jade Close. A great start for the Australians, and they are piling on the pressure in search of more goals.
