DeClue Loops Trail Race 2026

The DeClue Loops Trail Race takes place annually at Greensfelder Park in Wildwood, Missouri, on the DeClue Trail during October. Runners can choose their distance: one loop covers approximately 8 miles, two loops total 16 miles, a marathon distance follows three-plus loops, and four loops complete the 50K. The loop measures about 8.2 miles, beginning and ending near the park's Visitor's Center. Participants travel clockwise on each circuit. This format accommodates newer trail runners seeking a single circuit and seasoned runners desiring a longer challenge on Missouri's natural terrain of dirt, hills, and wooded parkland. Awards are presented to top finishers, and St. Louis Track Club members receive a registration discount using the email associated with their membership.
