Event overview

Tougher Together - 24 hours is a long time, but you don't have to go about this challenge alone. Take advantage of Tough Mudder UK's team relay options - allowing you to tackle the WTM course in teams of up to 4 people. Recruitment starts now, and no one is off limits. Fire up the group chat and rope in everyone from your closest friends and family to your best friend at work, or even that one Mudder you made friends with three years ago on Mud Mile.
