Tough Mudder

Tough Mudder is an epic obstacle course challenge that’s all about teamwork, courage and fun. You’ll take on muddy trails, icy water, electric shocks and extreme heights, all while testing your limits and supporting each other every step of the way. With different course lengths to choose from, there’s a Tough Mudder for everyone. Want to find out more? Visit the Tough Mudder website here.

There are 5K and 15K distances to choose from. The 5K course features 12+ obstacles, while the 15K challenge includes 20+ obstacles designed to test your grit and teamwork. Don’t worry if you’re not a runner, you can walk, jog, or tackle it at your own pace. It’s all about challenging yourself and having fun along the way

After you sign up, we’ll send you a training guide to help you prepare for event day. Tough Mudder involves a lot of running, especially in the 15K event along with obstacles that test your strength and endurance. Your training should include both running and weight or resistance training to build stamina and power. You can find Macmillan’s training plans here, and download Tough Mudder’s official training plans here.

Gym wear, old shoes and you very own Macmillan Technical T-shirt or vest that you can order when you sign up! Please be advised that you should not wear any cotton based garments on event day as these soak up the water on the course and it will be harder for you to stay warm.
