This is acutally helmetcam footage of a BMX racecourse in Chile, not Mexico, but props to Ufford on the headline anyway. But this is kind of a big deal: the Valparaiso Cerro Abajo Urban Downhill Race draws bikers from around the world and over 10,000 spectators each year, to the point where the city shuts down to facilitate the race. And you’ll soon see why I had to wear rubber underpants while I watched this. It’s amazing video.

The course took a toll on the riders, and vice versa–several jumps had to be repaired between runs. Filip Polc of Slovakia posted the best time of 2 minutes and 34 seconds, but I’m more impressed that nobody died.

Death defiance awaits you after the jump.
