Rennes Marathon
Race Day Weather
Comfortable temps, warming through the race
Mild 50°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 63°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. High humidity (82%) will make it harder to cool down through sweat — increase fluid intake accordingly.

First run in 2011, the race funds tree planting based on the distance each participant covers.
