About the Saint Louis Half Marathon
The St. Louis Track Club has held this race since 1980, which makes it the oldest half marathon in the region. It stays a club race rather than a festival weekend: park roads, a rolling start window, and a November slot that usually delivers good racing air.
Course
The route stays inside Forest Park, starting and finishing at the Muny Festival Grounds and using park roads and drives. It is gently rolling rather than pancake flat, and the organizers have reworked the routing recently, so pull the current map before planning splits.
Race-day weather
Early November in St. Louis is close to ideal for 13.1. Starts in the 30s or low 40s are typical, highs reach the 50s, and the open park stretches expose runners to whatever wind is moving.
