The Hidden Gem Half Marathon
The Hidden Gem Half Marathon is a road race held in Flossmoor, Illinois on September 12, 2026. The event is a half marathon distance and the 2026 edition is sold out.
The course is a pure road route with minimal backtracks through distinct, residential neighborhoods. The route passes through shady streets with residents commonly lining the course to cheer. The timing in September is noted as useful for runners preparing for the Chicago Marathon.
The event lists several participant conveniences and amenities: easy access from Chicago at under 30 miles south of the city, METRA train line service to the race, plenty of free parking, free beer after the race, runner swag and medals, and one of Illinois' largest cash prize pools. The race has received recognition from the Chicago Area Runners Association, including CARA Race of the Year and Best Race honors for 2022, 2023, and 2025.
Organizers describe the race as highlighting Chicago's South Suburbs and fostering community pride in Flossmoor. The presentation emphasizes neighborhood atmosphere, local support along the route, and logistical options for arriving by car or train.
