Des Plaines River Trail Races

The Des Plaines River Trail Races, held in Lake County, Illinois, offer a scenic and fast trail running experience with distances including a Half Marathon, Marathon (Boston Qualifier), 50K, and 50 Mile ultra. Starting and finishing at Half Day Forest Preserve, the course features a flat, wide, crushed gravel trail free of roots and rocks, winding through lush forests and open wetlands. Major road crossings are safely managed via bridges or viaducts, minimizing interruptions.

The race is known for its beautiful fall colors and is ideal for runners seeking personal bests. Aid stations provide water and snacks, and the event is cup-less, encouraging runners to bring their own hydration. Visit the organization's website for the most recent information.
