Cooper's Hill Cheese Rolling

From Boston.com:

Last Monday, May 25th, the annual Cooper's Hill Cheese-Rolling and Wake was held near Gloucester, England. In a tradition that dates back at least 200 years, possibly much longer, groups of fearless competitors chase an 8 pound (3.5 kg) round of Double Gloucester Cheese down an extremely steep and uneven hill, with a 1:1 gradient in some parts. Thousands of spectators gather to watch the five downhill and four uphill races, and to celebrate the winners and console the losers afterward. Injuries such as broken bones and concussions are commonplace, but the event continues to grow in popularity. The winner of each race is awarded the delicious round of cheese they were chasing.
