The event entails racers chasing a rolled wheel of Double Gloucester cheese down a steep hill. The run is extremely dangerous, with many racers tumbling all the way down the 200-yard slope. The day features several races for men, women and children.
Flo Early won the women's event this year but also suffered a suspected shoulder injury. Spectator Brad Poole said on Twitter she was carted off the hill but later returned with her arm in a cast.
According to GloucestershireLive, Chris Anderson, 30, won two races this year, bringing his lifetime total to a record 22 victories.
