Half Marathon-by-the-Sea
Race Day Weather
Comfortable temps, rain likely
Starting at 65°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Light winds shouldn't be a major factor for pacing. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. High humidity (92%) will make it harder to cool down through sweat — increase fluid intake accordingly.
