Runners follow a double-loop course for the Nitro Trail Half Marathon through Point Pinole Regional Shoreline Park, just a short drive from nearby San Francisco. With the exception of a few brief stretches along the park’s paved walking paths, most of the race takes runners along the natural surface fire trails through the park, and the race features ample views of the shoreline as well as the waters of San Pablo Bay.
