About Pretty Muddy

Get muddy as an individual or with a group of friends or family and raise money for life-saving cancer research.

Course information

The start and finish are on (grass). The course is mainly on grass and winds up and down the heath. The course crosses some roads around the heath, but these roads have been closed for your safety. The Blackheath course is relatively flat throughout.

Our courses are accurately measured with a measuring wheel, which may differ from GPS devices. Please follow the designated route closely to maintain the intended distance; cutting corners will affect your distance covered.

How Pretty Muddy® works

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.
