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

Course information

The start and finish are entirely on grass. The event site is on grass which is predominantly flat, however it can be uneven. Ground ground conditions may vary according to recent weather conditions.

The 5k Pretty Muddy course is a single lap. It is on a combination of grass and surfaced paths, and there is an 800m section on trail paths. An alternative route is available if required. It is mostly flat but there are some uphill and downhill gradients which all add to the fun and challenge!

There will not be any water refill stations along the course so if you require water during the event, please remember to bring your own reusable water bottle already filled up.  A Scottish Power water refill station will be available to use at the finish 

Please arrive 15 to 20 mins before your start time so that you are prepared and ready to go on time. 

Join forces or go solo

Bring a water bottle
We’re trying to reduce single-use plastic at Pretty Muddy. Please bring your own reusable water bottle, already filled. We'll provide an ecofriendly water-refill station at the finish that uses as little single-use plastic as possible.

Bring a change of clothes
If you’re getting Pretty Muddy®, remember to bring spare clothes and a towel. Check the facilities tab above to see what there is at your event. Unfortunately, there are no lockers, changing facilities or showers at the Race for Life events, so please bear this in mind and ask friends to look after your valuable belongings, clean clothes and towels.

Have the right kit
It’s a good idea to check the weather before your event and dress accordingly. Think breathable sports gear (leggings and shorts are ideal) and well-fitting trainers. For Pretty Muddy, wear something you don’t mind getting dirty.
Check out the latest range of Race for Life clothing and accessories in our online shop.

Be sun smart
Stay sun safe by finding shade when you’re not on the course and covering up with clothes, a hat and sunglasses. On parts you can’t cover, use sunscreen with at least SPF15 and a 4 or 5 star rating. Find out more about being sun smart.

Your back sign and race number
