Summer Nuts Challenge
The Nuts Challenge is an obstacle mud run held near Dorking in Surrey, close to London. It takes place on a permanent outdoor assault course that is operated year round and updated regularly with new layouts and obstacles.
The course combines trail running with a mix of natural and man-made obstacles. Elements on the course include mud and water sections, trenches, walls, cargo nets, tunnels, and features that require crawling, climbing and wading. The event offers multiple obstacle types across more than one lap option and reports a large number of individual challenges on the site.
Participants may enter alone, as part of a team, or run for a charity. The event also lists options for corporate days, bootcamps and group bookings. The organiser presents several distance choices and the possibility of completing multiple laps on the same course.
Distances and format:
- 5 km race option
- 10 km race option
- Multiple laps available
