Half Marathon Course Description:

Similar to the Dipsea Race, runners start their journey through downtown, running up Visitacion Ave before turning right on Mendocino St, then running up a couple of flights of stairs. At the top of the stairs, runners turn left on Humboldt Road, and then right on Trinity Road. As you crest the hill on Trinity Road, you’ll see the trail head on your left, beginning your journey on the trails of San Bruno Mountain.

Stay on the single track until you come to a wide trail. Turn left, and start heading up towards the top of the mountain. This trail eventually merges with the “Army Fire Road.” The toughest part of the race is the beginning, as this is where you’ll find most of your ascent. Once you reach the summit via the “Army Fire Road,” you’ll immediately understand why this is an amazing course, as your view left will be the Pacific Ocean, while your view to the right will be the Bay.

After some nice rolling hills on the summit (Ridge Trail), you’ll reach a trail marker where the Ridge Trail transitions from fire road to single track. At the end of the trail, turn left on the Summit Loop Trail, just before Aid Station #1 at 3.2 miles. From here, hold your water bottle tightly as you’ll be treated to a super fast, almost two mile long downhill single track trail (Summit Loop Trail). You’ll then go back up the mountain (Summit Loop Trail), before making your way down to the saddle (Dairy Ravine Trail to Eucalyptus Loop Trail), and to Aid Station #2 at 7.2 miles.

You will then run the Saddle Loop Trail, before coming back to Aid Station #3 at 9.9 miles. To make your way back to Brisbane, you’ll run back to the Eucalyptus Loop Trail (this 200 meter section is the only part you’ll run twice), before making a sharp left on Old Ranch Road Trail.

When you get to the “Utility Road” at the end of the trail, you’ll turn right. When you get to a water tank, take the trail on the left. At the bottom of the trail is Golden Aster Ct, which you will run half a block to a stairway. Turn right, and go down the stairs to Silverspot Drive. Make another right, and run to the bottom of Silverspot Drive, turning left at the crosswalk and running along W. Hill Drive. At the crosswalk, turn right on to the Crocker Park Trail, and take this to the ramp that leads to Quarry Road. At the top of the ramp, turn left, and hall ass for the next 400 meters to the finish!

The course will be marked the night before with pink ribbons. We’ll have volunteers at each decisive intersection. Each Aid Station will be well stocked with gels, water, sport drink, and other goodies.

The course is challenging, so be prepared! It is highly recommended that you bring your own water bottle.

Also, the course is surrounded by sensitive habitat. It was very difficult to get the permits to put on this race. Runners who do not stay on the trail will be disqualified! You will see plenty of volunteers with signs. They have the authority to disqualify any runner who does not stay on the trails. Please show respect for this beautiful mountain!
