Daredevil Cyclist Takes On Sedona's White Line Trail

Here's a video, shot using a drone-mounted camera, of professional mountain biker Michal Kollbek riding the White Line Trail in Sedona.

Actually, to call the White Line a trail is overstating things a bit. It's really just a line — a white stripe of sandstone across a nearly vertical red-rock cliff.

Kollbek, a native of Poland, told The Huffington Post that he'd heard about the trail but hadn't had a chance to ride it until he came through Sedona on a recent trip. He walked the route a couple of times, then slept on it for a couple of nights before deciding to try it.

Kollbek told his Instagram followers that the ride was "one of the scariest things I have done on a bike."
