About the Race

This event is tucked away in the incredibly beautiful foothills of the South Bay Area, taking place fully in the Rancho Cañada del Oro Open Space Preserve.

If you’re looking for easy and flat then move on. But the climbs here are well worth it: At the top is a panoramic view of the entire Bay Area southward, plus the base of the Santa Cruz Mountains.

The Open Space Preserve will give you a mix of singletrack (40%) and some very enjoyable fire roads (60%) to play on. There are lots of beautiful old oak trees to enjoy but lots of exposure, so come prepared.
