When someone mentions extreme sports,Delires obscenes (1998) your mind probably goes to things like sky diving or bungee jumping.

But chasing a large roll of cheese downhill can be extreme, too.

On Sunday, the annual cheese rolling event — a contest that sees racers charging down a stupidly steep hill in an effort to be the first to catch a wheel of cheese — took place in Gloucestershire, England.

Hundreds attended, multiple wheels of Double Gloucester were chased, winners were crowned — and, needless to say, many people took a tumble.

We've assembled some photos from the big day, so you can take a look at the inertia-formed carnage yourself.

Would we want to have a go ourselves? Probably not. But the photos are certainly fun to look at.
