About The Event
Join #TeamMacmillan as the official charity partner for Tough Mudder UK!
Take on the unforgettable obstacle course challenge at Culden Faw Estate (RG9 3AP) on Saturday 8 and Sunday 9 May 2027.
Choose between the 5K course with 12+ obstacles or the 15K challenge featuring 20+ obstacles both built to test your endurance, teamwork and determination. Secure your charity place for just £30, with a £300 fundraising pledge per person, and help Macmillan continue supporting people living with cancer every step of the way.
From ice-cold water plunges and deep mud trenches to towering walls and electrifying obstacles, this is an experience that will push you beyond your limits and leave you with memories (and muddy trainers!) that last long after the finish line.
Every challenge conquered helps fund Macmillan’s vital services, ensuring no one must face cancer alone.
