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 are both on grass. The course is on a mixture of tarmaced paths and grassy fields. Due to the nature of the venue, the course can get boggy in the event of severly wet weather in the lead up to the event.

The start line is on the north side of Coopers Field, opposite Orachard Lawns.
The finish line is on the south side of Coopers Field, opposite the Gorsedd Stone Circle.
