Life is worth Racing for. Enter Cancer Research UK’s Race for Life and raise money for life-saving cancer research.
Climb, crawl and slide your way around the Pretty Muddy® obstacle course at your own pace. 5k is just over 3 miles and can take about an hour to complete on average, but there's no pressure to finish in a certain time – it's all designed for fun! Get muddy as an individual or with a group of friends or family and raise money for life-saving cancer research.
The start and finish is on grass. The course is largely flat with a mixture of terrains, tree-line paths and grass avenues.
You can take part in any Race for Life event as an individual or a group to raise money for life-saving research. Walk, jog or run together in a group or go solo at your own pace, or lead the way as a Group Leader and get family, friends and colleagues involved! However you choose to get muddy, you’re helping to beat cancer.
Shake off any pre-Race nerves and get moving with our fun warm-up session just before your event.
Bring along as many supporters as you like to cheer you on! We’ve got things for everyone to do, check out the Location section above to see what’s happening on the day.
After you've completed the course, stay on and celebrate with other participants, friends and family with a picnic in the park.
