F3 Lake Half Marathon
The F^3 Lake Half Marathon & 5k is Chicago’s original winter half marathon, held annually at Soldier Field along the scenic lakefront. The event features a USATF-certified, mostly flat and fast course with mile markers and three aid stations offering water, energy drinks, gels, and restrooms. Runners start in self-seeded waves to reduce crowding, with pace groups ranging from 1:30 to 3:30 hours.
Participants enjoy pre-race warmth in Soldier Field’s United Club and receive a cozy hoodie and finisher medal. After the race, a festive afterparty is held at Weathermark Tavern. The event attracts thousands and offers prize money, making it ideal for winter training or spring marathon preparation. Visit the organization's website for the most recent information.
