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. Scheduled for August 30, 2025, the event features three race options: a half marathon, an 8-mile race, and a 5-mile race.

Participants will enjoy a beautiful course that winds along the Missouri River bluffs, with the half marathon covering both the Lewis and Clark trails. The event promotes sustainability by being cup-free, encouraging runners to bring their own water receptacles. Early registration guarantees a T-shirt and finisher's medal, making it a memorable experience for all participants. Visit the organization's website for the most recent information.
