It's really hard to pick the most insane thing on the Red Bull events roster, but surely the FoxHunt is near the top. A group of mountain bikers getting chased down a hill by a pro, likes foxes running from a hound, sounds like the perfect amount of fun and stupid in one go.
This year's FoxHunt is to be an all-female affair, with Rachel Atherton taking up the hunter's role. It's happening 27th-28th of September in Edinburgh (perhaps a foreign country by then), and you can register to be a part of it right now.
You can watch a video of last year's event, with Gee Atherton ripping down a hill in the Northern Irish countryside, above. It certainly got us pumped on the idea.
And if you need more convincing, here's a message from Rachel herself.
