Kelly McGarry is a freeride mountain biker who strapped a GoPro to his helmet and rode away down a narrow ridge. On either side, he would have been met with a steep fall. As if this wasn't amazing enough, he proceeds to do a backflip over a 72-foot canyon gap along the way! He only came up with second place, even with such a great run.
The video itself left many with sweaty palms. While watching the video, you can't help but wonder the amount of courage these riders have to do something like this. You really get a sense of appreciation viewing riders from this viewpoint.
Red Bull also featured this video of the backflip that shows him at another.
