Tough Mudder run gives you a chance to run an obstacle course, have fun and raise funds for Brain Research UK

Tough Mudder is a unique experience! It includes a range of obstacle courses and mud runs with teamwork and personal accomplishment at their heart. Whether it's a 5K or 10-mile course, you can expect world-class obstacles, a unique sense of camaraderie and an atmosphere like no other.

You can be a part of Team #BrainResearch 2021 Tough Mudder by either directly with event organiser or by running on one of our Charity Places (see further down this page).
