Comfortable temps, big temp swing, moderate wind, rain likely

Starting at 61°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temps will climb significantly to 77°F by later miles, so expect fading conditions as the race progresses. Moderate winds around 13mph may affect pacing on open sections of the course. Rain is likely — waterproof your phone and bib, and consider a disposable poncho for the corral. Moderate humidity at 72% is worth noting for effort level, especially in later miles.
