Mudders are tough. But NorCal Mudders are a special breed. Our thoughts are with every person, Mudder or not, who suffered through last season’s wild fires. And we’d like to extend a heartfelt welcome to any of you resilient warriors ready for a badass blast around the track at Tough Mudder NorCal 2018. This season, we’re taking NorCal’s course to Sonoma Raceway, where rubber meets mud, and the track takes as many twists and turns as Coach chasing post-workout snacks in a new city. Sonoma’s expansive course, crammed full of rolling hills and elevation changes, is sure to get your engine revving. No mud run’s ever been this close to the Bay Area before, which means no mud run’s ever been this epic. Tough Mudder NorCal 2018 is epic, elevated. Expanded. Upgraded.

10 Miles, 20+ Obstacles

So what’re you waiting for, Mudder? Collect your course conquering crew and take it to Sonoma Raceway in 2018, where Tough Mudder NorCal is ready to hit red line.

Sonoma Raceway is filled with grassy knolls, rolling hills, and some serious elevation changes that are sure to test every participant. Located only 45 minutes north of the Golden Gate Bridge, it’s the perfect place for a mud-filled weekend of fun with people of all ages and levels of fitness.


More than 10,000 participants and top endurance and obstacle course racing



TOUGH MUDDER WEEKEND filled with several events including:

  • Tough Mudder Half – 5-mile mud and obstacle course challenge featuring some of Tough Mudder’s signature obstacles – but excluding the more extreme elements such as ice and electricity. Tough Mudder Half provides a rewarding yet accessible challenge, serving as the perfect gateway series for introducing people to mud runs.
  • Tough Mudder – the signature 10-12-mile mud and obstacle course challenge designed to pull participants out of their comfort zone. With no winners or clocks to race against, it is not about how fast you can cross the finish line it is about teamwork and personal accomplishment.
  • Tougher Mudder – Tougher Mudder takes our signature 10-mile Tough Mudder course and adds a competitive, timed twist. This first start wave on Saturday of event weekend allows Mudders to push themselves to a new level on the classic course, while still maintaining our core values of teamwork and camaraderie. Cash prizing will be given out to the top three males and females.
  • Mini Mudder – one-mile obstacle course designed for children ages 7-12.
