Awesome New Venue, Exciting New Course

Tough Mudder Half NorCal holds a special place in our collective TMHQ heart. Following last year’s wildfires, know that you and your loved ones are in our thoughts, and we’d be honored if you came out in 2018 to show the course you won’t be cowed. This season, we’re setting up shop at Sonoma Raceway, crafting a course only the wildest Mudder unicorns can conquer. Best be ready to run though; the set-up at Sonoma ain’t no short track. The expansive Tough Mudder Half NorCal course is crammed full of rolling hills sure to test you as much on the way down as the way up, so make sure your crew’s souped up and ready to run. It’ll be fun, but it sure won’t be easy.

5 miles, 13 obstacles

Who wants easy anyway? You and your unstoppable crew want fun, adventure, and the Best Weekend of the Season. You’ll get all that - and more - at Tough Mudder Half NorCal in 2018.
