Join us for a Pretty Muddy 5k event 

No matter how cancer affects us, life is worth Racing for.

  • Pretty Muddy® is a 5k muddy obstacle course that you can take part in, no matter your fitness level. It’s designed for one thing: fun!
  • Climb, crawl and slide your way around the Pretty Muddy® obstacle course at your own pace. Find out more about the obstacles.
  • 5k is just over 3 miles and can take about one hour to complete on average. But there's no pressure to finish in a certain time. 
  • Get muddy as an individual or with a group of friends or family, have fun and raise money for life-saving cancer research.

Make the most of your Pretty Muddy day

Join forces or go solo. You can take part in any Pretty Muddy® event as an individual or a group to raise money for life-saving cancer research. Walk, jog or run together in a group or go solo at your own pace. You could lead the way as a Group Leader and get family, friends and colleagues involved! Whatever you do, however far you go, you’re helping to beat cancer.  


Warm up with other Race for Lifers. Shake off any pre-race nerves and get moving with our fun warm-up session just before your event.  

Supporters and spectators welcome. 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 of your event page to see what’s happening on the day. 

Soak up the atmosphere. After you've completed the course, stay on and celebrate with other participants, friends and family with a picnic in the park. 


Pretty Muddy® events start times are staggered in 'waves', each wave starts every 15 minutes to ensure you're safe on the course. If you're signed up as a group, please make sure you sign up for the same wave time.

Climb, crawl and slide your way around the course at your own pace. We want you to tackle every obstacle the best you can, but if you need to skip to the next one our marshals will be on hand to assist.

Find out more about Pretty Muddy® obstacles.

To be part of the action, you must be 13 years of age or older at the time of your event. We've got something special for our young participants too - check out our Pretty Muddy® Kids events for kids aged 12 and under!

If you have any pre-existing medical conditions, please seek your doctor's advice before registering.


5 kilometres is just over 3 miles and on average takes around an hour to complete depending on ability.

Our courses are measured using measuring wheels by our team of experienced Event Managers. Measuring wheels are the most accurate way of measuring course distances as they are not impacted by surrounding buildings or terrain, this is why the distance may be different from Garmin, Strava, Apple Watch & Fitbit technology.
