Every year a 9 lb round of cheese is sent rolling down the top of Cooper’s Hill, near Gloucester in England and the competitors start chasing after it. However, the cheese may reach speeds of up to 70 mph and the chances of catching it are pretty low. So, the person who crosses the finish line first wins the cheese. If you decide to take part in this competition, you should be extremely careful because the uneven surface of Cooper’s Hill may cause serious injuries.
