13th Annual F^3 Lake Half Marathon & 5k presented by Physicians Immediate Care

One of Chicago’s few remaining independently-owned large races, the 13th Annual F^3 Lake Half Marathon & 5k is Chicago’s Original Winter Half Marathon. We will be returning in-person once again at Soldier Field! We will follow state and local guidelines regarding large gatherings. To keep everyone safe we will not be using the indoor United Club, and will instead setup on the east side of Soldier Field.

Virtual option includes a race bib, hoody, medal, and shipping.
