Corps of Discovery Trail Races

The Corps of Discovery Trail Races, organized by the St. Louis Track Club, will take place in the scenic Weldon Spring Conservation Area on August 30, 2025. Participants can choose from three race options: a half marathon, an 8-mile race, and a 5-mile race.

The course features beautiful trails along the Missouri River, with the half marathon covering both the Lewis and Clark trails. This year introduces an 8-mile option, enhancing the event's appeal. Runners are encouraged to register early to secure a T-shirt and finisher's medal.

The event promotes a cup-free environment, urging participants to bring their own water receptacles. Visit the organization's website for the most recent information.
