San Francisco Half Marathon Pace Calculator & Race Plan

The SF Half runs across the Golden Gate Bridge and through the Presidio with 267 meters of gain. That's a lot of climbing for a half marathon. July fog keeps temperatures cool but the hills are real.

This is a course where elevation-adjusted splits make a big difference. Even pacing isn't realistic with this much climbing.
