Dirty Dozen and Half Dozen Endurance Run

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, 6 hour and 3 hour races going on.

Our races are The Dirty Dozen, Dirty Half Dozen and Quarter 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 picnic that will begin at 10:30 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.
