Event Details

July 7, 2018 will be the 9th edition of Dirty Dozen!

Join us at Point Pinole Regional Shoreline for a different kind of race! From 7:00 am to 7:00 pm, the running party won’t stop with 12 hour and 6 hour races going on. And even if you aren’t ready for that kind of “fun”, come join us for a nice run (and a chance to cheer on the 6 and 12 hour runners) with the Dirty 5K/10K in the morning or afternoon!

The “Big Races” are the 12 hour and 6 hour events: The Dirty Dozen and Dirty Half Dozen! These can be run by individuals or with teams of two or three. These races offer the opportunity to run without worrying about “finishing time”! Anyone who runs a single lap is automatically a “finisher” whether their total run time is 15 minutes or the full 12 hours.

Entry to any race includes the all-day BBQ/picnic that will begin at 11:30 am and go on the whole day!

All races will take place on a gentle 3.37 mile loop consisting of 98% dirt fire trails. Runners will go out along the shoreline (offering expansive views of multiple bridges and mountains) and then come back through the fragrant eucalyptus groves.

Hikers/walkers are always welcome!

Event Details

Come play at of one of the most fun and scenic events on the west coast. This race has a sprint and international (Olympic) distance triathlon, with relays and aquabike categories for both races. Clydesdale and Athena registration categories are available.

There is a special, non-competitive Family & Friends wave for people who are new to triathlon or just want to race with family and friends regardless of age or gender.

Sheltered swim and flat bike and run course make this a perfect place for your first race or a PR. Voted one of the best late season triathlons in the country. The bike ride is a totally closed course and both the bike and run courses follow the coastline to create one of the most scenic races around!

Stick around and play for a day at the famous Santa Cruz Beach Boardwalk or visit the Surfer Museum or National Marine Sanctuary Center.
