Prepare for an unforgettable trail running experience at the Headwaters Trail Run, set for June 20, 2026, in the stunning Klamath Mountains west of Mount Shasta, CA. This event, offering challenging distances of 52K, 34K, and 10K, promises breathtaking scenery and a true mountain adventure. Typical race day conditions in late June bring highs around 80°F and lows near 49°F, with a minimal 3% chance of precipitation, providing ideal running weather.

The longer 52K and 34K courses are scenic, mountainous loops traversing entirely on single-track trails and dirt forest roads, winding through the rugged terrain that gives rise to the Sacramento River's crystal-clear headwaters. The 52K boasts an impressive 8,000 feet of elevation gain, while the 34K is equally challenging with approximately 4,000 feet of ascent. Both routes incorporate sections of the historic Sisson-Callahan National Recreation Trail. For those seeking a faster, flatter experience, the 10K follows the picturesque Lake Siskiyou Trail, a local favorite, offering around 400 feet of gain on a 99% dirt surface. All distances are framed by the magnificent backdrop of majestic Mt. Shasta and Mt. Eddy, rewarding runners with clean mountain air and panoramic views.

Runners consistently praise the Headwaters Trail Run for its challenging yet runnable courses, well-stocked aid stations, and the enthusiastic volunteer support. This grassroots event is a cupless race, requiring participants to carry their own hydration vessels to minimize waste. Beyond the trails, participants are treated to a hearty, organic post-race meal prepared by local chef Jacqueline Hertzog, often described as "arguably the best post-race meal anywhere". The race also proudly supports the Mt. Shasta High School cross-country team, with a portion of proceeds donated annually. The start and finish lines are conveniently located at the south end of Box Canyon Dam on Lake Siskiyou.
