Second Paralympic gold for O'Hanlon

Two events, two gold medals, two world records.

That's the London 2012 tale of Canberra sprinter Evan O'Hanlon who ended his latest Paralympic campaign with victory in the T38-class 200m on Saturday.

"I came here and I've won 100 per cent of my races in world record time, the same as I did in Beijing," the 24-year old said after his win in 21.82 seconds, which shaved 0.16 seconds from his own world record.

While O'Hanlon, who has cerebral palsy, streaked ahead and was never troubled by his competitors on Saturday, he admitted the race challenged him.

"It's not that easy, I was feeling pretty ill afterwards," said O'Hanlon.

O'Hanlon collected his first London gold a week ago in the 100m event of the same class.

Juggling his university studies with athletics, O'Hanlon said he will be back for the 2016 Games in Rio.

Earlier on Saturday, NSW javelin athlete Georgia Beikoff took bronze in the F37/38-class event.

Saturday's result takes Australia's athletics gold medal tally to five on the final day of stadium action, with team green and gold still to contest another five events.
