The Cooper’s Hill Cheese Rolling and Wake is an annual event held on the Spring Bank Holiday at Cooper’s Hill,[1], near Cheltenham and Gloucester in the Cotswolds region of England.[2] It is traditionally by and for the people of Brockworth – the local village, but now people from over the world take part. The event takes its name from the hill on which it occurs.

From the top of the hill a round of Double Gloucester cheese is rolled, and competitors race down the hill after it. The first person over the finish line at the bottom of the hill wins the cheese. In theory, competitors are aiming to catch the cheese, but since it has a one second head start and can reach speeds up to 70mph (112 km/h), enough to knock over and injure a spectator, this rarely occurs.
