Cold start — layer up, big temp swing

Runners will start in chilly 32°F conditions — dress in layers for the corral and plan to shed early. Temps will climb significantly to 54°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.
