New Zealand's Rebecca Petch has bounced back from a nasty crash in heat one of her quarter-final BMX race.
Petch went flying over her handlebars midway through her first race when her front wheel locked up.
Petch was coming third at the time of the crash and finished in fifth with a time of 2:01. Japanese rider Sae Hatakeyama also crashed and did not finish.
But the 23-year-old dusted herself off and bounced back in heat two and three, finishing third and then second, to qualify for the semifinal.
