Heart of Cool Trail Run

The Heart of Cool Trail Run is a trail running event in Cool, California, at 860 Cave Valley Rd. The event offers multiple distances on local Sierra Foothills trails used by several well-known endurance races.

Distances:

  • 5k Trail Run/Walk: 3.1 miles
  • 10k Run/Walk: 6.2 miles
  • Trail Half Marathon: 13.1 miles

Entry fees are listed for each distance. A portion of event proceeds supports programs run by Georgetown Divide Ready by 21, Inc and some funds will be used to scholarship a child to attend Camp Taylor, a camp for youth with heart disease.

The event is family friendly and includes a family discount package for immediate family members for the 5k and 10k. Child care is available for children ages 3 and up for a fee of $8 per child. Half marathon participants will receive a new item for 2026, to be determined. Packet and bib pick up occur on race day. The event will be cup free to reduce waste; participants should bring a reusable cup or water bottle for aid station refills. Volunteer opportunities are available for the race and the day before.
