St. Louis Track Club is excited to invite everyone to join the 2023 Corps of Discovery Half Marathon and 5-mile trail races, held in the beautiful Weldon Spring Conservation Area on Sept 2nd, 2023

Course Description:

The course will cover approximately 13.1 miles and begin from the Lewis & Clark trailhead in the Weldon Spring Conservation Area off Hwy 94. Half marathon participants will first run the 8-mile Lewis trail and then the 5-mile Clark trail. The course will travel counterclockwise and will not be closed to outside use. There will be markings along the course and a volunteer where the trails split. The 5-mile option will cover 1 loop of the Clark trail. The trail winds itself along the bluffs of the Missouri River down the hardwood-lined ridges and into the hollows so all participants will have something to enjoy.

$75 - Half Marathon ($80 after 7/3/2023)

$55 - 5 mile race ($60 after 7/3/2023)
