BMX power-duo Saya Sakakibara and her brother Kai were chasing their childhood dreams of competing in the Olympics when everything changed. 

Kai suffered a traumatic brain injury after a crash in 2020. 

After seeing the impacts on her brother and suffering multiple concussions herself, Saya became terrified of the sport she loved. 

In this extended interview, Saya opens up about what she had to overcome to achieve her dreams, and why she decided to lay it all bare in her new book, Just Go: Turning Fear Into a Superpower.

Guests:

• Saya Sakakibara, Olympic gold medallist and author
