The Event Benefits

Partners & Advocates for Remarkable Children & Adults (PARCA), a local nonprofit whose programs help people with developmental disabilities lead more satisfying and independent lives.

Pets: Sorry. No dogs or pets are allowed at the Pacifica Community Center.


FREE parking will be available at the St. Peter Parish, 700 Oddstad Blvd, right next to the San Pedro Valley County Park gate. From there, you’ll be directed by event volunteers to the check-in area, near the park entrance. Due to the popularity of the event and limited number of parking spaces in the area, we ask participants to carpool if possible.
Parking at San Pedro Valley County Park costs $6.

  • Headphones: The use of headphones during the event is strongly discouraged due to safety concerns.
  • Carry water: Even though aid is provided, we ask participants to carry a bottle or hydration pack between aid stations, especially on the longer routes.
  • Bathrooms: There are bathrooms with running water at the start/finish area, but there are no bathrooms along the courses.
  • Dogs: Due to park regulations, there are no dogs allowed on the trail run events.
  • There will be course marshals stationed along the course to guide you. We ask that you follow their instructions.
  • There is reliable cell phone coverage along most of the course, but in case of an emergency, you should use the special call-in number listed on the course map provided at check-in. In the event of a serious medical emergency, you need to call 911 first.
