A cool 41°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 50°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 67% is worth noting for effort level, especially in later miles.
