The word 'legend' is often overused in sport, but even 'legend' doesn’t quite cut it with Greg Hancock. The Californian Speedway shredder is a three-time World Champion and even as the oldest man in the SGP field, he's still showing his back wheel to the young bucks trying to take him down. He didn't get his 'Grin' nickname for no reason - you can hardly take the smile off his face when he's away from the track but as soon as the helmet goes in he's a fiercely competitive racer with a steely determination to win. He's missed only one Speedway Grand Prix EVER - yep, in the history of the series - and he's showing no signs of slowing down at all. What a guy.
