The Peak 50K, Marathon & Half Marathon Julian, CA   Oct 17, 2026

If you love the mountains, the challenge of a good, long climb and quad-pounding descents, then The Peak is for you. Running mostly along single track trail with spectacular views, The Peak climbs Cuyamaca Peak—San Diego County’s second highest.

The 50K and marathon routes take you up on a 2,200 foot climb over the initial 6.3 miles of the course, then drop you down 2,800 feet to Sweetwater Aid Station and the marathon turnaround. The return marathon trip takes you back up to the top of Cuyamaca Peak for a total elevation gain and loss of 10,000 feet. 50K runners complete a five mile loop, returning to Sweetwater, before setting out on the same return trip as the marathoners.

The half marathon follows in the footsteps of the 50K and marathon, climbing up the challenging Conejos Trail before reaching the peak and a return trip back to the start/finish area.
