Warm start, big temp swing

Starting at 68°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temps will climb significantly to 92°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. Moderate humidity at 80% is worth noting for effort level, especially in later miles.

Both courses will be USATF certified, and the race is a last-chance Boston Marathon qualifier each September. Source
