Montara Mountain Trail Run Course Guide

It is a genuine coastal climb: the 50K stacks up about 6,700 feet of gain from San Pedro Valley Park, on a course that is 75% single track and 23% dirt road, with a sliver of asphalt. Montara Mountain rises straight off the Pacific coastline, so the climbing is sustained and exposed to ocean wind and sun rather than broken into short rollers. With a 9 hour overall cutoff and an intermediate 4 hour 15 minute checkpoint at 13.1 miles, it rewards a runner who respects the mountain from the start rather than one who tries to bank time on the early miles.

The 50K climbs about 6,700 feet total, the marathon about 5,840 feet, the 20 miler about 4,640 feet, the half marathon about 2,900 feet, and the 10K about 1,200 feet, all on the same Montara Mountain terrain, just less of it for the shorter distances. Because the longer distances share the same climbing terrain, the extra mileage on the 50K is almost entirely extra vert, not extra flat running.

Coastal Trail Runs (the organizer, sometimes billed as Coastal/Zoom events) runs a cupless race to cut down on waste and litter on the mountain, so there are no pre-filled cups of hydration at the aid stations. You need to bring your own means of carrying fluid, a bottle, flask, or hydration pack, and use it at every stop. The race sells Hydrapak SpeedCups at check-in for around $5 if you show up without one, and you can request a disposable cup from a volunteer in a pinch, but plan to carry your own gear rather than count on that.

With fully stocked aid stations every 6 to 7 miles carrying fresh fruit, salty snacks, assorted candy, water, and Skratch electrolyte sports drink, you have real chances to reset your intake, though the gaps are wider than a typical Coastal Trail Runs course. Aim for roughly 60 to 90 grams of carbohydrate per hour, and keep sodium in the 300 to 700 mg per liter range, leaning higher on the exposed coastal sections where ocean wind can dry you out faster than the temperature suggests. Because the race is cupless, carry at least 20 ounces of water between stations as the race itself recommends, and build a per-hour plan rather than relying on aid alone. Dial in your numbers with the free ultra fueling calculator before race day.

All events carry a 9 hour overall time limit, and there is an intermediate cutoff of 4 hours 15 minutes (12:15 PM) at the 13.1 mile mark. For a 50K starting at 8:00 AM, that intermediate checkpoint sits at roughly the race's midpoint by distance but well before its midpoint by time, so runners who fall behind there have real work to do on the back half of the course.

It can be, if you respect the vert and the coastal exposure. The course marking is dense (ribbons roughly every 200 yards, color coded by distance) and aid stations every 6 to 7 miles mean support is never far off, even if the gaps are wider than some Bay Area courses. The real test is the 6,700 feet of climbing on a 9 hour clock with a 13.1 mile intermediate cutoff to hit. If you have trained on real vert and pace the early miles conservatively, Montara Mountain gives a well-prepared first-timer a fair shot, and San Pedro Valley Park's undisturbed coastal habitat and Pacific views make the climb worth the effort.
