Maratón del Valle
Race Day Weather
Comfortable temps, big temp swing
Starting at 65°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temps will climb significantly to 90°F by later miles, so expect fading conditions as the race progresses. Moderate humidity at 72% is worth noting for effort level, especially in later miles.
