Greenbrier Half Marathon
Race Day Weather
Comfortable temps, warming through the race
Mild 55°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 66°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 75% is worth noting for effort level, especially in later miles.
