Comfortable temps, big temp swing, moderate wind

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 82°F by later miles, so expect fading conditions as the race progresses. Moderate winds around 16mph may affect pacing on open sections of the course.
