London’s Culden Faw Estate
Tough Mudder London West at Culden Faw is one of our most challenging courses of our season, packed with steep hills, dense woodlands, and muddy ditches. With elevation gains of up to 551 meters, it’s not for the faint-hearted (or weak quads).
Expect slippery, muddy pathways, natural obstacles that ramp up the difficulty, and muddy ditches galore you’ll have to wade through. Historically, London West brings unpredictable weather conditions, and often, mudslides.
Camping is also available for those who just can’t get enough of the mud and want to continue the festivities into the evening.
What You Can Expect From the Mud
Brace yourself for the filthiest fun you’ll have all year. London West isn’t just big— it’s massive, with over 15,000 Mudders ready to slip, slide, and get absolutely caked in the good stuff. Expect the muddy madness you love, cranked up to 11, with thousands of like-minded legends bringing the energy.
You can run a 5K with at least 12 obstacles or a 15K with 20 obstacles. Not tough enough for you? Sign up for Europe’s Toughest Infinity, an all-day, 12-hour event with as many laps as you can handle. Expect the unexpected.
In return, finishers will receive a medal for their respective distance, honorary headband, t-shirt, finisher drink, and a load of goodies from our sponsors.

The adventure doesn’t have to end at Tough Mudder. Henley-on-Thames and West London have plenty to keep the good times rolling.
