Mild 54°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 69°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready.
