Naperville Trails Half Marathon

Lace up your shoes for the scenic Naperville Trails Half Marathon, an exceptional 13.1-mile journey through the beautiful Danada Forest Preserve in Wheaton, IL, on Saturday, September 5, 2026. This well-regarded event, often celebrating its 14th year, is a highlight on the Chicagoland running calendar and proudly benefits the local chapter of the Special Olympics. Runners can anticipate a course primarily composed of soft, cushioning crushed limestone trails, which many find to be easier on the joints than asphalt, making for a comfortable stride through wide-open forests, prairies, and wetlands, including views of Rice Lake. While largely flat, the course features some rolling hills, with an elevation ranging between approximately 720 and 780 feet above sea level. The unique finish around a grass equestrian racetrack adds a memorable touch to your accomplishment.

The Naperville Trails Half Marathon boasts a reputation for being well-organized, with enthusiastic volunteers and plentiful aid stations stocked with water and Gatorade Endurance Formula strategically placed throughout the course, typically near miles 2, 4, 6, 8, 10, and 12. Pacers are also available to help you achieve your goal time. Starting and finishing near the historic Danada Equestrian Center, the race offers a supportive atmosphere. Typical race day conditions in early September usually see highs around 80°F and lows around 58°F, with a relatively low chance of precipitation. This half marathon is frequently recommended by participants for its beautiful course and excellent support, making it an ideal choice for both seasoned trail runners and those looking to experience a welcoming trail race.
