San Francisco Marathon
Race Day Weather
Mild start, adjust for hills
Runners will face a temperature trend starting at 58°F and peaking at 69°F, with average humidity at 75%. A headwind will challenge the early miles, especially from 1 to 9, requiring pacing adjustments. As runners tackle the hills, particularly the climb from miles 6 to 7, hydration should be prioritized. Tailwinds will assist from miles 16 to 24, providing a boost for the final push.
