We’ve all heard of Britain’s Tough Mudder and their 20km obstacle races but once every year they step things up a notch… significantly!

The annual World’s Toughest Mudder challenges contestants to complete as many laps of a gruelling five mile obstacle course as they can in 24 hours.

Obstacles include a huge quarter pipe named Everest, a stretch of ‘Hang Tough’ suspended rings and a ‘Leap of Faith’ from a high platform to a suspended cargo net.

Taking place in November, it’s a wet and cold experience throughout, forcing athletes to run for the majority of the time in full wetsuits. Amazingly, the course record currently stands at 20 laps or 100 miles!
