A New Breed of 5K
Everyone knows the west coast is the best coast, that's why Tough Mudder 5K Sonoma at Sonoma Raceway is gonna be the most epic bash of the 2020 season. Only an hour from downtown San Francisco, you and your muddin’ crew will cruise over grassy knolls and take in expansive beautiful vistas before you get wild at the Mudder Village Festival.
3 Miles, 13 Obstacles
Tough Mudder 5K is pulling out all the stops for an epic bash so fun you’ll have no choice but to have the time of your life. It all starts and ends in our Mudder Village Festival with killer live entertainment, epic games and challenges, authentic local eats, and a never ending-supply of Mudder Nation camaraderie. After you’re done crushing the course, the good times keep rolling with a frosty cold finisher beer and your new best friends from course.
Epic action. Legendary party.
