Untimed mud-and-obstacle challenge built around teamwork, not the clock.
Outdoor Trail Untimed 20 events in the catalogue
Overview
What it is
Tough Mudder 5K and 15K are not races — nobody is timed, obstacles are built for teamwork, and finishing comfortably is the whole game. Your plan is built for comfort and logistics, not performance.
Competition exists only in the Endurance Series: Infinity (8-hour multi-lap) and World’s Toughest Mudder (24-hour).

- Tough Mudder 5K: 12+ obstacles
