Headwaters Trail Runs

Mount Shasta, CA 50K, 30K, 10K

This Event Took Place Sat. Sep 30, 2017

Cancelled Event


The September 26, 2020 event has been cancelled in an effort to reduce risk of spread and contamination of COVID-19. This decision has been made with the health and safety of the runners, event volunteers, and local community in mind. We expect to return to normal operations in 2021.


Headwaters Trail Runs are 56k, 31k, and 10k trail running events held in the Klamath Mountains west of Mount Shasta City, CA. These three scenic trail runs are named after the headwaters of the Sacramento River.

The 56k and 31k races are scenic, mountainous loop courses (the 56k adds a 15-mile out-and-back section to the 31k loop). They are run entirely on single-track trails and dirt forest roads that wind up, down, around, and through the rugged mountains that claim host to the crystal-clear headwaters of California's longest river. Both races include miles on the historic Sisson-Callahan National Recreation Trail.

The 10k race is a relatively flat, fast loop on the lake trail that circles the forested shores of picturesque Lake Siskiyou. The Lake Siskiyou Trail is a favorite trail for local trail runners of all abilities.

The magnificent backdrop for all runs is majestic Mt. Shasta (14,179' elev.), the most massive of all the Cascade volcanoes, and Mt. Eddy (9025' elev.), the highest peak in the Klamath Mountains. Runners are rewarded with clean mountain air, challenging terrain, fully-stocked aid stations, and a welcoming and enthusiastic volunteer staff.

Awards & Prizes

Top 3 overall female and male receive awards from our sponsors. Top 3 female and male in each 10-year age group receive age group awards.

Additional Information

All participants receive a hearty, organic meal made by local chef Jacqueline Hertzog - arguably the best post-race meal anywhere! Participants also receive a commemorative race t-shirt, and a unique finisher's medal.

Headwaters Trail Runs is a cupless event, and runners will need to carry with them a means to get drink at the aid stations. We do our best to reduce the waste generated by this event in all aspects. Please consider bringing your own reusable plate, utensils, and cup for the post-race meal.
