If you're ever in the town of Brockworth in England at the end of May,you'll have the chance to watch a very strange sport cheese-rolling has been a tradition in Brockworth since the 1800 s. Someone pushes a large, round piece of cheese down a hill and the competitors chase after it. No one has ever caught it, but the person who reaches the bottom of the hill first gets the cheese! It sounds easy, but lots of people fall and get hurt. Last year's winner said, 'If I hadn't taken part in the race, I wouldn't have believed how steep that hill is!'
