Kawerau's Sarah Walker has a mountain to climb if she is to qualify for the Rio Olympics after a crash in morning practice at the BMX World Championships in Colombia yesterday.
Walker will hope that a damaged shoulder suffered from the fall will allow her to ride competitively in tomorrow's elimination races in Medellin.
The rider rolled around the circuit in the time trial yesterday to record a time which ensures a start in elimination racing tomorrow.
But if she is fit to race tomorrow, she will need to finish in the top two individuals who have not already qualified to enable the London silver medallist to compete in a third Olympics.
"It's gutting for her," said Cycling New Zealand BMX coach Ryan Hollows. "Sarah has trained so hard after coming back from her broken arm and had been strong in practice yesterday.
