About the race
Des Plaines River Trail Races is an endurance trail event held in Lake County, Illinois, starting and finishing at Half Day Forest Preserve. The program features a Half Marathon, Marathon (Boston Qualifier), 50K, and 50 Mile ultra. Runners traverse a 100% trail course on a fast, flat crushed gravel surface, with few road crossings thanks to bridges and viaducts.
The out-and-back routes follow the Des Plaines River Trail through alternating lush forests and open wetlands, with dramatic color changes. The race is cup-less, offers ample aid stations, finisher medals, and post-race meals, and may use an alternate course if flooding occurs.
