Taking place on Saturday, October 11, 2025, the Des Plaines River Trail Races offer an exceptional running experience along the scenic and tree-lined Des Plaines River Trail at Half Day Forest Preserve in Vernon Hills, IL. Runners can choose from four distances: Half Marathon, Marathon, 50K, and 50 Mile Ultra. The course is flat and fast, run entirely on crushed gravel, and features minimal road crossings, making it ideal for those seeking a smooth trail race or Boston Qualifier (for the marathon distance). All participants receive finisher medals, with 50 Mile finishers earning a commemorative belt buckle. The event emphasizes sustainability as a cupless race, encouraging runners to bring their own hydration systems while enjoying aid stations, a supportive race crew, and a peaceful autumn setting.
