NorCal Tue Niter: Twin Peaks San Francisco

Start with a lap of the Polo Fields, San Francisco's historic bike racing oval. Exit into Golden Gate Park, head and exit the park onto Stanyon. Stanyon climbs southward to Parnasssus, which climbs westward to Medical Center Way. Medical Center climbs thru the trees to Mt Sutro. A brief descent leads to Twin Peaks Blvd, which continues climbing to the famous Twin Peaks. A lap around the peaks and to scenic Christmas Tree Point takes you to the twisting descent to Portola Ave, then a right turn leads back north on 7th Ave to Golden Gate Park. A lap of the park brings you back to the Polo Fields, for a finishing circuit before the S/F banner.
