First back to back Saturday – kick off at 8 am on 15k, then 5k around 11am
The flattest course of the season, ideal for first-timers.
Set in the rugged beauty of the South West countryside.
Expect twisting woodland trails, thick mud pits, and classic obstacles designed to test.
It’s the perfect blend of scenic and savage.

Part of the same journey
Another trip to the Lake District, but this time the running shoes are coming with me.
The Grasmere Wild Trail Runs have been on my radar as exactly the sort of event that fits into the Tough Smudge journey. It isn't an obstacle race and it isn't about chasing a flat-road 10K time. This is about getting more experience running properly off-road, dealing with hills, changing surfaces and the sort of terrain that makes ten kilometres feel very different from ten kilometres on tarmac.
The first major endurance rehearsal. Tough Smudge heads to London West for an eight-hour Infinity on Saturday, before returning on Sunday for both the 15K and 5K. The Infinity target isn't a distance award. It's to complete the experience, learn from it and discover how much is left when it's time to go again.
The Tough Smudge journey heads to Holmbush Estate for Tough Mudder London South 2026. Another 15K, another 20+ obstacles and another chance to build experience, endurance and resilience on the road to World's Toughest Mudder 2027.
