Brazen Dirty Dozen Race Info

Summary: The Brazen Dirty Dozen races take place on a 3.37 mile loop consisting of 98% dirt fire trails in the Point Pinole Regional Shoreline (SF Bay Area). Runners will go out along the exposed shoreline and then come back through more shaded eucalyptus groves. Both 12 hour and 6 hour options, as well as a 5k and 10k, and relay options for team of 2 or 3 as well. An additional .67 mile loop will be available to run for the last hour of each timed event — starting at hour 5 for the 6-hour runners and hour 11 for the 12-hour runners. Walkers and hikers welcome, as there are no cutoffs other than the overall time limit.

Lessons Learned from Race Reports

  • Course described as rolling hills with partial shade, with the smaller loop having more of a speed bump than the bigger loop, which could be difficult later in the race when you’re already tired
  • Likely to become quite warm, into the 80s, even if the average temp isn’t that high
  • Lots of runners bring tents or canopies, or at least a folding chair for resting in, eating, changing, storing gear, getting some shade…
  • In pictures, the portions of the trail without shade look very sunny, hot and very exposed
  • Likely to have some breezes to cool you off that close to the water
  • Remember sunscreen!
  • Bumpy and uneven footing through the start/finish chute
  • Hills will seem small at first and then will grow as the race goes on
  • Helpful to have crew and/or a pacer for the second half of the race when all the 6 hour runners are done

Aid stations

Total aid stations: Countless, halfway through each loop and at the start/finish, which is every 3.37 miles.

What’s available: Stations will be stocked with water, sports drink, and sweet and salty snacks like fresh fruit, candy, pretzels, chips, bagels, sports gels and other snacks. The start finish/area will also include hot food of different varieties throughout the day, including things like soup, chili, pizza, etc.

Crew access

Access Locations: Start/Finish, so every 3.37 miles


Nothing explicitly said either way, but since more than one team member can go out at once, it seems that people running with a single runner would be ok.
