It’s not too long now until over 17,000 Warriors, young and old, will be taking to the mud, ice fire and waters of beautiful Bramham Park. It’ll be our 11th year at this iconic Yorkshire estate and we’ll be celebrating in style both at Bramham Park and at our official Afterparty Venues in central Leeds.

If you can’t run this year, be sure to rally your team for 2026 and take advantage of our event weekend offer.

12K Warrior opens at £59.95* and entries open at midday on Saturday, 21st June. You won’t find more pain for your pound—we’re almost half the price of similar Tough Mudder events.

If you’re free on June 21st – 22nd June, be sure to swing by and and show your support to the runners. Unlike other big events, we don’t charge spectators to enter and for one weekend only you’ll have full access to one the UK’s most beautiful country parks. Be sure to have a swig at our brand new Northern Monk Aching Arms bar too!
