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.

The courses will showcase the beautiful trails along the Missouri River, with participants running on the Lewis and Clark trails. This year introduces an 8-mile option, and all registered runners will receive a t-shirt and finisher's medal. The event promotes a cup-free environment, encouraging participants to bring their own water receptacles. Visit the organization's website for the most recent information.
