Welcome to the 14th edition of the DPR Trail Half Marathon, Marathon, 50Km, and 50 Mile along the beautiful and fast Des Plaines River Trail in Lake County, Illinois starting and finishing at Half Day Forest Preserve.
The DPR Trail is truly awesome and the color changes are OMG-worthy! You'll run through beautiful alternating lush forests and open wetlands on a very flat, wide, crushed gravel trail, free of roots and rocks. All of the major road crossings are managed by way of bridges or viaducts (with only 4 minor road crossings along the whole 50K/50 Mile course, 2 on the Marathon course, and none for the Half Marathon course).
With expected cool temperatures, flat terrain, and ideal running surface, you'll find this trail to be extremely fast, which is perfect for a personal best, or a Boston Qualifying time. (The Marathon is a Boston Qualifier!) Come out and join us for a great run!
