Tough Mudder London South 2025

Join our Tough Mudder team and take on the most popular obstacle course in the world!

The BIGGEST and BEST Tough Mudder course is back for 2025 and it’s going to be great! With no competition and no timing, it’s just you, your teammates and muddy strangers working together to conquer the course and earn the world-famous orange headband.

Although Tough Mudder events are the definition of hardcore, there are plenty of reasons to laugh and smile – you can’t take yourself serious when you’re covered in mud! Take part as an individual or a group and test your physical and mental strength! Perfect for corporates, groups of friends/family or even take it on by yourself!
