From the BBC:
Chris Anderson, 18, won one of the five races which make up the annual contest, in which dozens of people race down a 1:2 gradient hill after a large cheese.
St John Ambulance workers at the race, on Coopers Hill in Brockworth, said two people were taken to hospital.
One spectator was given treatment after being hit by a runaway cheese.
The competition, which is thought to date back hundreds of years, consists of a series of downhill races with the winner of each receiving a seven to eight pound circle of cheese. Runners up get £10 and there is a £5 prize for third place.Jim Jones, St John Ambulance operations training manager, said 12 spectators and 13 competitors had been injured during the event.
"It was quite a reasonable year, not too bad at all," he said. "We usually average around 30-40 people who need treatment.
"The most serious injuries this year appear to be a dislocated finger and a possible fractured ankle."
Organiser Richard Jefferies said the wet conditions had helped keep the number of injuries down.
"The rain I think actually helped because it meant people were more likely to slip down the slope than go head over heels," he said.
