Tough Mudder Returns For The Filthiest Fun You’ll Have All Year

The ultimate test of endurance and teamwork kicks off at Culden Faw Estate on 10-11th May 2025 with the event hosting over 15,000 participants across an adrenaline fuelled weekend. 

Tough Mudder is back, bringing the ultimate test of endurance, teamwork, and grit to London West on 10-11th May 2025. Hosted at the breathtaking Culden Faw Estate, launching the 2025 season, the event will see 15,000 participants tackle adrenaline-pumping obstacles, muddy terrain, and an unbeatable atmosphere of camaraderie you can only find on the Tough Mudder course.

With distances for all fitness levels, from 5K to 15K courses to the debut of Europe’s Toughest Infinity (a 12 hour endurance event featuring mind busting penalties and non-stop loops of the course), participants will face the legendary Blockness Monster, plunge into ice cold water that will jolt your senses before scaling the iconic Mudderhorn - a towering cargo net climb pushing you to new heights.
