High up on Skyline Boulevard in the Santa Cruz Mountains between the towns of Woodside and Half Moon Bay, California lies the magnificent Purisima Creek Redwoods Open Space Preserve that is open year round for trail runners to enjoy. Within the boundaries of this undeveloped and protected parkland you will find exquisite single track that offer sweeping views of the Northern California coastline. This extensive trail system winds through dark, dense strands of first and second growth redwoods and along the peaceful Purisima Creek.

At the height of the lumbering industry and during the Gold Rush, Purisima's overflowing redwood forests were being clearcut to supply the demand for the prized wood. Imagine a time when teams of oxen, lumberjacks, wagons and small cabins crowded the forests. To warn of falling trees, whistle punks would alert these bustling mills with a blaring ring of his steam whistle.

The BayTrailrunners Whistle Punk Deuce is the first organized trail race ever held in Purisima Creek Redwoods OSP! It is open to all levels of trail runners. While it is mostly non-technical, there are some considerable uphill climbs for both distances. The half has 3000' of elevation gain while the full boasts 6600' of punishing gain. Experts can use this race to measure their progress, while first time racers looking for a new challenge will find this to be an excellent starting point to their trail racing adventures.

Marathon runners who finish in 6 hours will earn 2 points towards entry to Ultra-Trail du Mont-Blanc®

Aid Stations

Aid will be provided throughout the course. You can expect fruit, carbs, sweets, water, and Skratch hydration and nutrition products. There will be a water stop at the 6 mile mark where Grabtown Gulch and Borden Hatch Mill join. Another will be setup at 9 miles with nutrition and water at the bottom of Purisima Creek where your climb up Whittemore Gulch begins. Marathon runners will get water at the top of Harkins Ridge (13 miles) before their second loop and a long descent to the main Aid Station at the bottom of Purisima (16.5 miles). Water again at the top of Grabtown (19.5 miles) and one more visit to the Purisima AS (22.5 miles) before the ascent up Whittemore to the finish. We strongly recommend that all runners carry some form of hydration pack or water bottle throughout the race.

Cut Offs

Marathon runners will have 3.5 hours to reach the 13 mile mark. This is where North Ridge and Harkins Ridge connect for your second loop. If you fail to make it to this intersection in the allotted time, you will be directed to the finish where we will drop you down to the half. This is a mandatory rule we must respect so we do not go overtime on our permit and use of the park.

The BayTrailrunners Trucker

Just $25 will get you our BayTrailrunners embroidered, adjustable Trucker! There are 3 colors available for purchase at checkout. Army Front/ Moss Mesh back, Navy Front/ White Mesh back, Orange Front/ Moss Mesh back. We will have it for you on race day!
