There's only one rule in this race and it's pretty simple - the first one to the bottom gets to keep the cheese.
Everyone starts at the top of the hill and waits for the large Double Gloucester to be released and then chases after it.
Even though it's only 90m from top to bottom, it's a steep slope and can be pretty dangerous. There are always doctors ready in case someone gets hurt.
Every year, the race gets more and more popular. This year competitors were cheered on by a massive crowd of about 6,000 people.
