Corps of Discovery Trail Races

Follow in the footsteps of legends on historic trails at Weldon Spring Conservation Area. Tackle a fast-and-flowy loop through hardwood-lined ridges, or take on the rugged Lewis Trail with its Missouri River views and hollow-to-ridge climbs. Combine both loops for the ultimate test. This is a cup-free event; a reusable HydraPak SpeedCup is provided to help keep the area pristine as we race responsibly.
