San Francisco Bay Area Marathon Pace Calculator & Race Plan
The San Francisco Marathon is the premier bay area marathon, running through some of the most iconic scenery in American road racing. The course crosses the Golden Gate Bridge, winds through the Presidio and Haight-Ashbury, and follows the Embarcadero along the waterfront. With 319 meters of elevation gain, this is a genuinely hilly marathon that includes steep neighborhood climbs and the sustained ascent to the bridge deck.
The marathon in SF's Bay Area presents a unique weather challenge. July mornings typically start in thick fog with temperatures in the low 50s, but by late morning the sun can break through and push temps into the 60s or higher. Our pace model adjusts for the front-loaded hills and shifting conditions so you can stay conservative through the climbs and run the flatter back half with confidence.
