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 and at the finish. You can expect the standard aid station fare of fruit, carbs, sweets, salty snacks, water, Skratch hydration and Clif nutrition products. We strongly recommend that all runners carry some form of hydration pack or water bottle throughout the race.

  • Half and Full Marathon runners will have a water and electrolyte stop 6 miles in at the Borden Hatch aid station.

  • Half and Full Marathon runners will have full aid at the 10 mile distance at the Purisima Higgins Aid Station.

  • There will be a water stop for Marathon runners only at the 13 mile mark, and the start of their second loop. Half Marathon runners will proceed straight to the finish for aid.

  • Marathon runners will again see full aid at the Purisima Higgins aid station at the 16.5 mile distance.

  • At the 19.5 mile distance, Marathon runners will again find water and electrolyte at the Borden Hatch aid station.

  • Another pass for Marathon runners at the fully stocked Purisima Higgins aid station at 22.5 miles before the final climb to the finish.

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.

Just $25 will get you our BayTrailrunners embroidered, adjustable Trucker! There are 4 colors available for purchase at the race. Army Front/ Moss Mesh back, Navy Front/ White Mesh back, Orange Front/ Moss Mesh back, Charcoal Front/ Black Mesh Back. We will have plenty for sale on race day!
