The San Diego 50 and Trail Marathon course will feature some of the beautiful trails of the San Dieguito River Park and the Black Mountain Open Space Park. The course will be a mix of double track, single track, fire road and a very small amount of paved running.


Starting at the San Pasqual Valley Trailhead, 50 Mile and Marathon runners head WEST on the San Pasqual Valley Trail. This takes runners up and over Raptor Ridge and on to the Mule Hill Trail.
Once reaching the Mule Hill Trail Head, runners will be diverted along the edge of the parking lot to the trailhead of the North Shore Lake Hodges Trail. This trail passes under Hwy 15 on a paved walkway, however there is dirt along the walkway if you would prefer to not run on the paved path.
Once off the paved path, the trail becomes very scenic as you run a combination of double track, fire road, and single track all overlooking Lake Hodges.
Marathon runners turn around just short of the marina and return along the same route they took outbound.
50 Mile runners continue on past the marina toward Del Dios Community Park.
From here, the trail continues along the lake towards the Lake Hodges Dam where it connects to the Del Dios Gorge Trail.
Once reaching the end of the Del Dios Gorge Trail, you continue on to the Santa Fe Valley Trail.
From this trail, you enter a series of switchbacks that take you in to Black Mountain Open Space Park along the Lusardi Creek Loop Trail and your turnaround.
Upon reaching the turnaround, 50 mile runners return along the exact same route you took outbound.
