Tough Mudder – South London

September 20, 2025 - September 21, 2025

You’ve heard of the phrase ‘save the best till last’, well you couldn’t be more right about Tough Mudder London South on Saturday 20 or Sunday 21 September. It’s the biggest and best for a reason and that’s not just because it’s a well known stomping ground for obstacle testing. You’re going to need a hefty team to get you through the surprises on course for 2025. We’ve seen the obstacle line up… and it’s not looking pretty.

Try the Tough Mudder 5K or 15K obstacle course and shake up your boring run with world-class obstacles. The event takes place at Holmbush Estate, West Sussex.

You will also need to commit to raising either £200 (5km) or £300 (15km) in sponsorship for the Centre. There is a registration fee of either £20 (5km) or 30 (15km) + booking fee.
