Parking will be at the Mt. Wilson parking lot. The start will be in the parking lot and then proceed down Mt. Wilson Road to Eaton Saddle. Runners then follow Valley Forge Trail down to Gabrielino Trail.  This route gets the runners off the paved surface and onto groomed hiking trails.  Runners follow the Gabrielino trail to the left away from Valley Forge and towards Red Box Fireroad and the Red Box Aid Station (mile 6.8).

Runners leave Red Box Aid Station on Red Box Fire Road, runners will continue on this tree-covered grade all the way to the West Fork Aid Station (mile 11.1).  Runners leave Westfork on Red Box Fire Road and climb up to the Newcomb Aid Station (mile 14.9). This aid station is located where the hill ends and the road widens. This is the same location as the AC 100 Newcomb Aid Station. Runners leave Newcomb Saddle on Red Box Road, follow the road to the “T” intersection of Rincon-Edison Road, and turn left to follow Rincon-Edison Road towards Shortcut. The course goes down to the San Gabriel River (the lowest elevation on the entire course) and then climbs to Shortcut. Two miles below Shortcut there is a “water-only” Rincon-Edison Road aid station set-up as an added safety station (mile 22.05). 

Runners have drop bags and crew access at Shortcut (mile 24.05). Runners do NOT cross HWY #2. Runners will leave thru the Forest gate on the Fire road, but turn right approximately 0.45 miles on to the historic Silver Moccasin trail. Runners will follow Silver Moccasin back to Westfork Aid Station (mile 27.85). Upon leaving this last aid station, all runners take the Gabrielino Trail going west to the base of the Kenyon Devore Trail. The final climb, which offers spectacular views, ascends the Kenyon Devore Trail (1910 ft in 3.1 miles) up to the Mt. Wilson Summit Finish (33.1 miles total). The course has approximately 6195 feet of elevation gain and loss and is completely within the Angeles National Forest.
