Tough Mudder Midlands, Belvoir Castle, Grantham, Lincolnshire, NG32 1PE
You will be taking on one of our most technically difficult events on the calendar. All the obstacles are up-scaled for this event with a number of tweaks and surprises in store due to the varying (and muddy) terrain. The course route will take you through scenic views of Belvoir Castle, a number of killer hills and plenty of incredibly muddy tracks.
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
