Tough Mudder South West, Badminton Estate, Badminton, South Gloucestershire, GL9 1DD
New to Tough Mudder? Start here. This is the flattest course of the season, ideal for first-timers, but don’t let that fool you. Set in the rugged beauty of the South West countryside, it’s still every bit a Tough Mudder. Expect twisting woodland trails, thick mud pits, and classic obstacles designed to test your grit. It’s the perfect blend of scenic and savage.
Whether you choose the 5km or 15km distance, you’ll be joining thousands of Mudders pushing their limits while raising vital funds to support mental health - participants must be 17 to take part.
Registration fee: £30 Minimum fundraising target: £300
Charity places & how to register
We have a limited number of charity places available for this event. To apply for a place, please complete the 'Apply for a Charity Place' form on this page. If your application is successful, we’ll send you a registration link to pay the £30 charity registration fee. Your charity place will only be secured and confirmed once this payment has been received.
Once registered with us, we’ll email you full instructions on how to complete your official Tough Mudder sign-up. When signing up on the Tough Mudder website, you’ll be able to choose your event day and distance (5km or 15km) - you won't need to pay anything extra. As part of your registration, a personal fundraising page will be automatically set up for you via Givestar, so you can start fundraising straight away.
Please note: Tough Mudder Infinity is not included with Mental Health Foundation charity places and requires a separate entry.
