MACKAY BMX champion Melinda McLeod has arrived back in town, just days after crashing out of the UCI world championships in Birmingham, England.

Last Sunday morning Australian time, McLeod, in her quarter-final elite women's heat three race was turning the second bend when United States competitor Amanda Carr inadvertently clipped her back wheel.

That contact sent McLeod, 19, flying from her bike just five seconds into the race and brought a premature end to her Olympic qualifier competition.

The fall gave her concussion and large grazes on her left shoulder and hip.

McLeod remains an outside chance of filling one of two Olympic women's spots when the Australian Olympic cycling squad is announced on June 24.

"Caroline Buchanan has all but sealed one of the women's Olympic BMX spots and it's come down to either Lauren (Reynolds) or myself for the other one," she said.

"In recent months there has been nothing between her and myself in recent competition and I'm not sure at all which way selectors will go.

"I'm prepared for the worst but wanting the best."

McLeod said her crash in the world championships happened so quickly there was no time to prepare for the fall.

"I was off to a really good start and the four us at the front all came over the first jump together," she said yesterday.

"On the second jump I saw the first American (Brooke Crain) crash just inside me, so I slightly adjusted my line around her. The next thing I don't remember much.

"On the footage it shows Amanda clipping my back wheel, but it was just a freak accident. There was nothing I could have done to prevent it.

"Amanda didn't intentionally take me out. It was just one of those things."

McLeod said selectors might still take into account her track record at representative level.

They might also consider her demonstrated medal potential when choosing between her and Reynolds for the final London Olympics female BMX spot.
