The consequences for failure in BMX at the Olympics are high. New Zealand’s Sarah Walker knows about this – she’s broken 18 bones over her career.

A big crash meant she missed out on Rio 2016 after her silver medal at London 2012.

She believes that the definition of failure should be reassessed.

“(Society sees) failure as such a bad word. It’s so negative and this thing that you need to avoid (but) I aim to fail every week.

"Then if I have a bigger failure – I have practiced that feeling – and I am more comfortable with it and I am more accepting of the outcome.”
