Bird vs Bike

Gee Atherton teams up with the BBC for an alternative approach to downhill training.

Gee Atherton has faced a lot of tough competitors in his time, but when he was hunted by the fastest bird in the world, a peregrine falcon, he had to make sure he was at the very top of his game. 

This BBC Earth project sees Gee tear down the trails of Antur Stiniog in Wales in the ultimate experiment between man and bird.
