Saint Louis Half Marathon

The Saint Louis Half Marathon and 5K, organized by the Saint Louis Track Club, is the longest-running half marathon in the St. Louis region, held annually in historic Forest Park. Both races start and finish at the Muny Festival Grounds, featuring brand new courses for 2025.

The event offers an open start format, allowing runners flexibility in their start times. Prize money is awarded to the top three male and female finishers in the half marathon, along with age group awards, while the 5K recognizes the top three overall finishers. A virtual participation option is also available, supporting the St.

Louis Crisis Nursery charity. Visit the organization's website for the most recent information.
