Riding Twin Peaks
Explore Twin Peaks on an indoor cycling loop from the Castro in San Francisco. Everycol’s route climbs by Clayton Street, follows the Twin Peaks Boulevard figure eight, then returns through Portola Drive and Upper Market.
The ride begins and ends at the Castro. That makes the descent part of the route, not a separate ride after the summit. The elevation profile shows the complete loop so you can compare the climbing section with the return to the start.
The climb from the Castro
The mapped itinerary starts at Market Street in the Castro and heads toward Clayton Street before reaching Twin Peaks. The city approach is included in the route distance, so the figures describe more than a segment timed only on the upper boulevard.
Around Twin Peaks and back
The route follows the upper figure eight, continues along the southern part of Twin Peaks Boulevard and descends by Portola Drive. Upper Market and the curve of Market Street bring the ride back to the Castro. Follow the map to see how the ascent and return fit together.
A city loop for an indoor ride
Twin Peaks combines a defined climb with a return to its starting point. For a ride that travels farther from the city, compare Golden Gate Park to Hawk Hill. For a longer summit approach in Marin, explore Mount Tam from Mill Valley and its separate elevation profile.
