F3 Lake Half Marathon

F^3 Lake Half Marathon & 5k is Chicago’s Original Winter Half Marathon, held at Soldier Field in Chicago. Thousands gather in the warmth of Soldier Field’s United Club before braving a windy lakefront course that is USATF-certified for both the half and 5k. The course features mile markers, three aid stations, self-seeded waves with pace groups, and enthusiastic volunteers.

Runners receive a hooded sweatshirt and finisher medal, with a post-race party at Weather Mark Tavern offering a free beer for medal wearers. Spectators are welcome, gear check is available, and the event maintains a community, winter-running atmosphere. Pacers provided by Fleet Feet and Chicago Endurance Sports.
