Reardon, a single leg above knee amputee, won the T42 100m on Monday in a time of 11.21 seconds from Daniel Wagner of Denmark (12.30) and Britain's Richard Whitehead (12.39).

"I came here with a plan to execute the first 20m of the race and put a bit of pressure on the rest of the guys," Reardon said.

"I think there's a thought that I can't run very fast because of my little legs, but when I execute a race well and I'm out in front, I'm tough to catch. I did that well, and that's what matters most at a championship like this."

Reardon has lobbied for double above knee amputees to compete separately due to the circular motion of their running style and it's a move that has angered Whitehead.

"I will only have a 200 metres to run in Tokyo, which is ridiculous," Whitehead said.

"We want the 100 and 200m in Tokyo. The IPC need to (include), not take it out of the program, they need to talk to us and understand why.

"Scott Reardon is a great athlete, but as a person he's someone that wants to provide himself with the best opportunity of success, not to compete. That's not me saying it bitterly, that's me saying it truthfully.

"I've seen emails from Scott and the Australian authorities that have looked at the reason why we shouldn't be involved and that is for 'danger' reasons, which is ridiculous."
