8 Hours. Through the night.

Exclusive Obstacles...Only on

We’ve taken Toughest Mudder and turned it up to 12 on the holy-sh*t meter for 2019. That’s right, it’s gonna be a full 12 hours of extreme teamwork, stamina, and mental grit testing action from 8pm Saturday to 8am Sunday. Haul through as many 5 mile laps as you can while attacking 20 of the most insane obstacles on the planet in pursuit of Mudder glory and all-new 2019 awards and prizes.
