Rend Lake Half Marathon
Race Day Weather
Cool start — fast day potential, warming through the race
A cool 49°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temperatures rising to 62°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing.
