The event follows mostly single-track trails and climbs Cuyamaca Peak, which is identified as San Diego County’s second highest. The 50K and marathon routes begin with a 2,200 foot climb over the first 6.3 miles, then descend about 2,800 feet to the Sweetwater aid station and the marathon turnaround. The marathon return trip includes repeated ascents and descents for a reported total elevation change of about 10,000 feet. 50K entrants complete an additional five mile loop that returns to Sweetwater before following the marathon return route. The half marathon follows the Conejos Trail to the peak and then returns to the start/finish area.

The published course is divided into numbered sections with turn-by-turn directions; major trail and road segments include Milk Ranch Road, Black Oak Trail West, Azalea Glen Fire Road, Conejos Trail, Lookout Road, West Mesa Trail, Monument Trail, West Side Trail, Harvey Moore Trail, Pine Trail, Juaguapain Trail, Dyar Spring Trail, and East Side Trail.
