It looks like a roller-coaster, only way more dangerous.

Warning: this may make you lose your lunch. Captured with a GoPro helmet cam, the video shows mountain biker Kelly McGarry's descent down a steep Utah mountain path, finishing off with an insane backflip over a 72-foot-wide gap in the canyon.

McGarry's ride was part of an event sponsored by that purveyor of all things dangerous and attention-grabbing, the Red Bull Rampage 2013. What's probably most insane is that the death-defying run only clinched him second place. (The winning run included a move that's probably fittingly called a "suicide no-hander").

Watch it with the sound, if only for the horrifyingly real soundtrack of McGarry's intense breathing at each obstacle.
