WHAT YOU EARN

(IF YOU CROSS THE FINISH LINE)

Event Bib

Every athlete receives participant bib to rock during (and after) the event. A true memento.

Medals

And as if 24 hours of absolutely mayhem wasn’t tough enough, interlock this hard-earned hardware with the Infinity and Toughest Mudder medals to reveal the Holy Grail — the ultimate endurance achievement.

Finisher Headband

Just like every Tough Mudder event, you earn the right to rep a sweet finisher Headband.

WTM Finisher Shirt

Whether you’re gunning for the podium or the top of your age group, prizes are on the line for qualified Contenders at WTM.

TOUGHER TOGETHER
24 hours is a long time, but you don’t have to go about this challenge alone. Take advantage of our 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.
BUILD YOUR TEAM
PREPARE FOR THE PIT
We’re not just leaving you alone in the dark.

The World’s Toughest Mudder atmosphere is unlike anything you’ve ever experienced before. The pit is complete with reserved campsites, food trucks, music, event announcers, and a full race center – making it the perfect place to pull off the ultimate all-nighter. We have something for every racer (and their mighty pit crew recruits).
SECURE YOUR PIT CREW / SPECTATOR PASS
BREAKFAST OF CHAMPIONS
Recover from 24 hours in the mud with an all-you-can-eat buffet. But, don’t get distracted – this community event is more than just a chance to stock up on your third plate of bacon or hobble to the water cooler to rehydrate. Sit back and celebrate during the awards ceremony, and watch as World’s Toughest Mudder victors and Legionnaires are honored for their accolades.

Space is limited – book your tickets and accommodations early to secure your spot.
