About the challenge

The ultimate obstacle course now has 12+ obstacles over a 5 kilometre run or 20+ obstacles over a 20 kilometre run.  

Be one of 15,000 Mudders to prove you're tough enough to conquer probably our most technically difficult obstacle course on the calendar. Well-known for being one of our hilliest events of the season, the course route will take you through forest trails, muddy ditches and up to 551m of elevation. That finisher beer will never taste more worthwhile. 

With no competition and no timing, it’s just you, your teammates and muddy strangers working together to conquer the course and earn the world-famous orange headband. 

Your entry includes a finishers medal, finishers shirt and finishers headband.
