Think you can handle a bike? High-speed Alpine descents and mad dashes through city traffic don't faze you at all? This video of Red Bull Rampage competitor Jeff Herbertson barrelling down a canyon and landing a backflip over a 73-foot gap will make you think you should go back to stabilisers.

The venue is the natural terrain of Utah, where the organisers have plotted a course designed to challenge the world's best off-road riders.

It's heart-in-mouth stuff even before Herbertson gets to the gap jump. If you get seasick, you might want to hold on to your chair

Herbertson came seventh in the event. Not being exactly mountain bike experts we wonder just what the heck you have to do to come first? Maybe you have to be made of PlayMobil.
