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 68°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 73% is worth noting for effort level, especially in later miles.

The Run in Lyon half marathon starts beside the Palais de Justice in Vieux-Lyon and follows the full marathon course along the Saone and through the Presqu'ile as far as Place des Terreaux. It then crosses the Rhone at the Pont Morand and runs down the Rhone banks, over the Pont de la Guillotiere, and back to a finish on Place Bellecour.
