This week for sporting history I'm joined by Katherine Oberlin-Brown
At just 19 she was the women's two-time Motorcross World champion...
The first time anyone had held the title back-to-back.
Katherine had a glittering career in front of her. She might still be riding today... If it weren't for one fateful moment.
A training crash that left her with just a 50% chance of ever walking again.
