Online registration will close on Friday 5/18 at 10:00PM (PST). Race day registration will be available  (Half $60, 5 Mile $50, Youth $20). You can read the race day details online here.

The scenic course may humble you, with its 1,880 feet of climbing and descending - but at the same time, the remarkable surroundings will energize you as you navigate the lush hiking trails of the Santa Cruz mountains. Along the course, you'll be shielded by redwood and oak forests and bordered by sprays of vibrant wildflowers. The climb will take you just shy of reaching Skyline Blvd. Who wants to be reminded of traffic anyway? At the turn-around aid station, you'll be able to fuel up for your descent back into Woodside. 5-milers turn around at an earlier point along the course. This is the half marathon that will rocket you towards your spring marathon goal. The event is limited to 300 participants so don't wait too long to register!
