DeClue Loops Trail Race : overview

The DeClue Loops Trail Race is set for October 11, 2025 at Greensfelder Park in Wildwood, Missouri. The event uses the DeClue Trail, described as an 8.2-mile loop that begins and ends near the Visitor's Center. Distance options offered are:

  • 8 miles (1 loop)
  • 16 miles (2 loops)
  • Marathon 26.2 (3 loops+)
  • 50K (4 loops)

Awards will be presented to the top male and top female for each distance. Race shirts are included with registrations made through 9/25/25. Members of the St. Louis Track Club receive a $10 discount when registering with their club email address.

Course and race logistics

The course features rolling hills and technical trail sections. A manned, stocked aid station is located at about the 3-mile mark with snacks and Tailwind; a water station is located at about the 6.2-mile mark just across Scenic Road. Tailwind is also served at the start/finish area. All aid station food is pre-packaged and the event is cup-free, so runners are strongly advised to carry personal hydration. Drop bags will be available near the start/finish for access between loops.

Race registration and headquarters will be at the yellow gate at the DeClue Trailhead. Parking is available near the Visitor's Center, at Muckerman Shelter, and at the gravel lot that leads to Round House. The course will be marked with orange flags and signs.
