Sally Pearson says if her rivals can only just beat her when she runs badly, they don't have a chance when she's at her best.
The world champion 100m hurdler has vowed to be back in personal best form and run around the 12.2 second mark at the Olympics after her first loss in 10 months at the Diamond League meeting in London a week and a half ago.
The loss disappointed the Queenslander, but also proved to her that her challengers still have a lot of ground to catch up on before the first round heats at the Olympic Stadium on August 6.
"People thought it was a shock because I came second. To me it was more of a schlock how badly I ran the race," she told reporters on Monday.
"If I can run a bad race and they can only just beat me like that, then when I run a good race, they're not going to stand a chance."
She ran a relatively slow 12.59 to come second in atrocious conditions at the Crystal Palace meeting after hurting her back in a fall during the warm up, well short of her best for the year of 12.40 and a long way shy of her 12.28 personal best set last year.
American Kellie Wells beat her with her best run of the year in 12.54, while Pearson's biggest rivals, Jamaican Brigitte Foster-Hylton has a 2012 best of 12.51 and American Dawn Harper has run 12.65.
"When I'm at my best it's going to be hard to beat me," Person said.
"These girls need to slice off a good chunk of their personal best times to really challenge me.
"Me and my coach Sharon (Hannan) will be doing everything possible to run back in the 12.2s again by the Olympics. I'm definitely capable of doing it.
"These girls have a big job to do if they want to get anywhere near those times.
"I wasn't at my best at the LOndon Diamond League, but I'm sure I will be in two weeks."
Pearson says her ongoing back problems affected her run at Crystal Palace but she's fully recovered from the stiffness and will be back to full training on Monday afternoon at the Australian team's camp at the exclusive Tonbridge School in Kent.
"The back's really good, I've got my first hurdles session this afternoon since London, I'm clawing at the walls to get over some hurdles," she said.
Wells showed how much beating Pearson means to her with a victory jig at Crystal place, but the Australian says she wont be dancing at the Olympic Stadium.
"Obviously it's not the Olympic gold medal, who knows what she'll do at the Olympics," Person said.
"She definitely won't be doing the dance, because she won't have gold."
