Set for its 15th annual running, the F^3 takes place along Lake Michigan in February 2024. In 2016, the race saw over 2,000 runners cross the finish line with 1,860 of them from the half marathon alone.
The out and back course is run almost entirely on the Lakefront trail, with very little elevation change. Participants will start the race outside of Soldier field, home of the NFL team Chicago Bears. Runners interested in other attractions nearby can check out The Field Museum, Shedd Aquarium and Adler Planetarium, all located around the starting line.
