Registration officially opened Jan. 12 for the 2020 Hidden Gem Half Marathon in Flossmoor — eight months to the day before the second annual race will take place — and organizers have received a boost in the event's status.
The Chicago Area Runner's Association, which certified the 2019 Hidden Gem, has added the race to a more exclusive club, its Runners' Choice Circuit.
