About the event

 

Why not take on a Tough Mudder! This is an intense, team-oriented endurance event designed to challenge participants both physically and mentally. Known for its signature obstacle courses, Tough Mudder features a variety of epic challenges such as crawling through mud pits, scaling slippery walls, and plunging into icy water.

It’s all about teamwork and camaraderie and with varying levels of difficulty, Tough Mudder offers experiences for beginners to seasoned athletes, making it a unique test of grit, strength, and determination.

By taking on a challenge event you’ll help us support over 350 babies, children and young people who are seriously unwell – helping them, and their families, to make the most of every day.
