Normally the hardest obstacle you'll need to navigate at the local 'cross race is a wooden hurdle or a steep grassy bank. Although, of course, the former of those has proved itself pretty tricky in the past.

But throw in a moving obstacle and things can get a bit tricky. We present footage from a Monster Cross race in Chesterfield, Virginia. You'd need a quick dismount to hop that one.

Okay it's not quite in the same league as a mountain biker getting taken out by an antelope. But still worth a watch.
