THE RACE
SATURDAY, SEPTEMBER 11, 2021
Run the Hidden Gem Half Marathon down the idyllic tree-lined streets of Flossmoor! Recognized by CARA (Chicago Area Runners Association) as one of “Chicagoland’s most well-organized and well appreciated races,” the second annual Hidden Gem Half Marathon has been named a CARA Runners’ Choice Circuit Race.
The Hidden Gem is a pure road race with minimal backtracks as the course winds through the six distinct neighborhoods of this culturally rich Chicago suburb that is less than 30 miles south of downtown Chicago. Discover the community of Flossmoor, a hidden treasure of the Chicago Southland known for its historic homes, award-winning parks, world-class golf, and warm inclusivity.
The Hidden Gem is an ideal race for both the serious and casual runner. Anyone training for the Chicago Marathon will appreciate the September timing, while those with more modest goals are sure to enjoy a terrifically entertaining run through beautiful, shady neighborhoods complete with cheering residents. The Hidden Gem is easily reached as Flossmoor sits at the nexus of all major interstates serving Chicago and is home to a conveniently located METRA train station that offers regular service to and from the City.
The top three overall finishers in the men’s and women’s divisions will be awarded generous cash prizes, and the top finishers by class will be recognized with awards. All participants will receive a medal.
BUZZ ABOUT THE GEM
Highly recommend this race for its friendliness, organization and all the little things they do to make it special. I traveled all the way from Miami to run it and fell in love with Flossmoor.
Today's run was amazing! Great course and even better people. Throughout the entire race people were cheering us on, from the students at HF to the residents sitting out on the lawn everyone was cheering. I hope this event happens again next year. I will be there!
Loved every single aspect of the race! Great planning, amazing spectators, HF band and cheerleaders, and all ending up at Flossmoor Fest with the Hidden Gem brew at the finish. My new favorite half!
THE COURSE
Flossmoor's Hidden Gem Half Marathon is an all paved course past parks, schools, churches, sculptures, and golf courses. Located only 30 miles from downtown Chicago in the heart of the Southland, this USTA Certified 13.1-mile race will take runners through Flossmoor's quaint, historic, tree-lined neighborhoods.
