From coast to coast and around the globe – every weekend – a Tough Mudder is happening somewhere. Each has its own adventure, its own devilish twists and unexpected turns. Find your spirit of adventure through a not-your-everyday Tough Mudder destination, and book your event now.
Answer honestly: What could possibly be more epic than pushing past your limits with a massive castle crowning a glistening green hill behind you? With the Belvoir Castle ground’s mud likely still settling from the previous weekend’s all-night obstacle fest – our extreme 24-hour challenge, World’s Toughest Mudder – a technically difficult countryside setting, and an always-looming chance of torrential rain, this will be one of our muddiest and most memorable weekends of the year.
Here’s everything you need to know about Tough Mudder Midlands.
Tough Mudder Midlands: The Dirty Details
- Location: Belvoir Castle, Grantham, Lincolnshire, NG32 1PE, UK
- Date: 5-6 July 2025
- Distances: 5K/12+ obstacles (Saturday and Sunday), 15K/20+ obstacles (Saturday and Sunday), Infinity/8 hours (Saturday)
Belvoir Castle: Where Stunning Views Meet Serious Challenges
Just 6 miles west of the UK’s town of Grantham in an area teeming with historic estates and manors, Belvoir Castle towers above the challenging course situated within its expansive grounds. Vast, rolling grassy hills are contrasted with dense woodlands at the drop of a hat, which will not only make for tons of trail technicality and steep inclines/declines that demand your utmost endurance and strength, but the varied and everchanging terrain creates the perfect setting for deep, muddy pits and water-filled trenches. We hope you plan on packing a backup pair of shoes.
We’re even making some special tweaks to all of your favourite obstacles to make this boggy course one of our most difficult on the calendar. Plus, it rained heavily on our Midland Mudders last year and they survived… ish. Just saying. 
Choose Your Distance (or Cheer on Your Friends)
Ready to conquer killer hills with scenic rewards? There are muddy milestones for everyone in your squad at Tough Mudder Midlands. Choose from a 5K format with 12+ obstacles or a 15K with 20+ obstacles, or – if you really feel like going the distance – see how many laps you can complete in 8 hours with Tough Mudder Infinity, offered on Saturday only. Get competitive and try to beat our 85K record, or take it easy with friends for an anything but average weekend outing. Either way, you’ll leave with unforgettable memories and an insatiable itch for a clean pair of clothes. Worth it.
If you’re not quite ready to hit the course yet – or if a friend invited you out to cheer them to the finish line – grab your Spectator Pass to join in on all of the post-course fun at our iconic Mudder Village Festival.
What You Get
In return, finishers will receive a medal for their respective distance, honorary headband, t-shirt, finisher drink, and a load of goodies from our sponsors.
Make It a Weekender
We know there have been times when you’ve had such a smashing time on the course that you’ve wondered, “What if I didn’t have to leave?” Well good news: Camping is coming to Tough Mudder Midlands this year, so you and all of your best mates can celebrate your accomplishments under the stars right when your event concludes. After you’ve (hopefully) rinsed down, just pitch your tent, BYOB, cook some well-earned grub in the open air, and make lifelong memories with fellow Mudders all weekend long. Book your pitch now.
Fancy something more up-market?
For our high-maintenance Mudders, the beautifully refurbished Vale House – situated at the foot of Belvoir Castle – offers limited bespoke, carefully designed guest rooms, and the surrounding Engine Yard features weekend pastimes and libations within minutes of one another: have a proper English breakfast and enjoy live music at the Belvoir Bistro, take home seasonal specialties from the Belvoir Farmshop, and take the entire family to Belvoir’s Adventure Playground – a four-acre playground for kids (and – of course – those who are still kids at heart).
