  • 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.

How does Pretty Muddy® work?

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.

How far is 5k?

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

How is Race for Life Pretty Muddy® measured?

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 and Fitbit technology.
