Tough Mudder London South 5K Sunday charity places for 2025

Elevate your Tough Mudder experience by raising money for one of these great causes, connecting with other people and enjoying a discounted entry fee!

Mud with meaning

Make those muddy miles count.

When you rock up to the start line in your branded charity t-shirt - potentially as part of a group, which is how many people fundraise for Tough Mudder - you can expect an extra level of love and support from fellow Mudders and the crowd!

Signing up to run for charity as a solo entrant will help you to meet other people on the day who are also fundraising, connecting you with like-minded people to take on the course together.

Discounted entry

Taking part in an obstacle course race is an unforgettable experience, removing you from the humdrum of everyday life and helping you to create memories with family, friends or colleagues by doing something out of the ordinary. Signing up to run Tough Mudder for charity helps you get to the start line by significantly reducing your entry fee in return for fundraising a target amount.

There’s nothing like the feeling of crossing the finish line and earning your headband. Now imagine you’ve crushed that goal not only for yourself but for the greater good. That's pretty epic.
