There's a bike race that takes place in the French Alps every year called the "Mountain of Hell" . . . and there's video of a big pileup soon after it started on Sunday, and – hard to believe after watching this video – there wasn’t any serious injuries.

It was just a crash waiting to happen.  There are 700 riders taking off at the same time and they're traveling down a snowy glacier.  All it took was one guy to fall and BOOM.

The race itself looks amazing.  It's a 15-mile course of snow, ice, rocks, and dirt . . . and the guy who won it this year hit 78mph.
