THE “MERCILESS METRIC CENTURY” (64-MILE)
The Merciless Metric Century is a demanding 64-mile ride with 5500′ of elevation gain that takes you down the spectacular San Mateo County coastline, up winding mountain trails, past ancient redwoods and back through pristine watershed areas. This route is recommended for seasoned distance riders with recent experience or teams who seek new challenges and a hard-earned sense of accomplishment. Riders under 18 must be accompanied by a parent or guardian.
For 2019, all three of our road ride routes have been enhanced for your safety and enjoyment, and now include a scenic detour through the peaceful, winding backroads of Half Moon Bay. See map below for more details.
