DeClue Loops Trail Race

Lace up for the DeClue Loops Trail Race on October 10, 2026, a premier event in Missouri's trail racing scene held within the scenic Greensfelder Park in Wildwood, MO. Runners can choose their challenge from an 8-mile single loop, a 16-mile double loop, a full 26.2-mile marathon, or a demanding 32-mile (50K) ultra. Expect invigorating autumn conditions with typical race day highs around 72F and lows near 47F, alongside a low 10% chance of precipitation, providing ideal temperatures for tackling the trails.

The heart of the DeClue Loops Trail Race is its challenging 8.2-mile DeClue Trail loop, known for its rolling hills and technical, steep, and rocky terrain. Starting and finishing near the yellow gate at the DeClue Trailhead by the Visitor's Center, the course guides runners counter-clockwise through a dynamic landscape. While the majority of the park is wooded, the course also features unique savannah and prairie ecosystems, showcasing wildflowers, grasses, and gnarled chinquapin oaks that offer a distinct visual experience. Aid is readily available with a manned and stocked station at the 3-mile mark offering snacks and Tailwind, and a water station around the 6.2-mile point. Remember, this is a cup-free event, so runners must carry their own hydration.

Consistently rated highly by runners, the DeClue Loops Trail Race promises an unforgettable experience for all skill levels, from seasoned ultrarunners to those new to the trails. The course is meticulously marked with orange flags and arrows to guide you through its challenging yet rewarding miles, though runners should be mindful of the technical aspects. Between loops, runners have access to drop bags near the start/finish. Celebrate your accomplishment with fellow trail enthusiasts at the post-race gathering, complete with beer and non-alcoholic beverages.
