Life is worth Racing for. Enter Cancer Research UK’s Race for Life and raise money for life-saving cancer research.
Get ready for an unforgettable day out as you climb, crawl and slide your way around the Pretty Muddy® 5k obstacle course! Sign up as a group with friends and family, or go solo and join hundreds of people on the day. There's no pressure to finish in a certain time, so take it your own pace, get muddy and enjoy the atmosphere. However you take part, you're helping to beat cancer.
The start and finish is on grass. The course is largely flat with a mixture of terrains, tree-line paths and grass avenues.

The start and finish are at the top of the slope next to Cassiobury Park car park located alongside the "Lebanon Tree".
