Tough Mudder
Tough Mudder stages a series of eight or ten races each year around the UK (and about 30 around the world), and as the name suggests, they involve running and plenty of mud. They also involve obstacles, most of which - in keeping with the spirit of the series – involve teamwork in order to complete them. There are different levels of Tough Mudder: Halfs are around 5 miles with a dozen or so obstacles and full Tough Mudders are around 10 miles of running and mud with about 20 obstacles. Beyond this there are variants that include longer times and additional obstacles, night-time races, a 24-hour race, and a competitive series. The event website can be found at toughmudder.co.uk
