It's basically a 400m climb, but at high altitude and without a safety harness. These people be cray.

Red Bull hosted the steepest race in Europe last month, the 400 Planica in Slovenia, and while it doesn't necessarily look that difficult, the fact that people are actually falling into the finish line says otherwise. Also, what the hell happens if you slip or decide you need to stop halfway? Slide back down? The shame.
