COURSE: 50k, 8-mile and 16-mile runners will start at the yellow gate and head down toward Round House making a left onto DeClue Trail. Marathon runners will also start at the yellow gate but will make a quick right to do a 2.4-mile loop on Dogwood Trail before heading onto DeClue. Once on DeClue runners will enjoy rolling hills and technical trails with a manned and stocked aid station at the 3-mile mark (with snacks and Tailwind) and a water station at about 6.2 mile mark just across Scenic Road. At the bottom of a nice hill runners will turn left on Eagle Valley trail, which will bring you up a nice climb to the top, behind the Visitor’s Center and across the street to the yellow gate start/finish area. Whether you are doing the loop once or 4 times, we hope you all take time to pause and enjoy all that Greensfelder Park offers.
The course will be well marked with orange flags and signs/arrows to guide runners. You can also check out the orange DeClue Loop on the Trail Map found here: https://stlouiscountymo.gov/st-louis-county-departments/parks/places/greensfelder-park/
