Antoine Bizet participated in the 2017 Red Bull Rampage, which I assume is a bike race, with a GoPro on his helmet. The course looks completely insane from this angle. It packs in quite a few terrifying moments in little over a minute. Make sure you have something to hold on to while you watch.
You couldn't pay me enough money to try biking down such a narrow trail at that speed. But Bizet flips, he jumps, he flies through the air, and he won the People's Choice Award for his run. -via Geekologie
