Half Marathon
Event Description
The 17th Annual F^3 Lake Half Marathon & 5k is Chicago's Original Winter Half Marathon. Each year, thousands of runners flock to this community-built event, gathering in the warmth of Soldier Field's United Club before tackling wind & weather along a lakefront course that features splits every 5km. A must for anyone preparing for a spring marathon or just resolving to stay fit throughout the new year. F^3 sold out in 2016-2020 and 2023-present.
Every registrant will once again receive one of our great hoodies and a medal! We will return to the warm confines of Soldier Field's United Club! The UC opens at 8 a.m. Gear check is available. The half marathon starts at 10 a.m. and consists of self-seeded waves in quick succession. The 5k is scheduled for 10:30 a.m. Courses close at 1:30 p.m.
After the race, head to Weathermark Tavern for the afterparty! 1503 S. Michigan Ave. Free participant photos are always uploaded to flashframe.io

Course Description
The USATF-certified course is mostly flat & fast along Chicago's lakefront. Each mile is marked with an F^3 feather flag. There are three aid spots on the course, each of which is passed twice, offering 6 chances for water, Gatorade, or bathrooms. Pacers will once again be provided by Fleet Feet & Chicago Endurance Sports. Pace groups typically provided are: 1:30, 1:45, 2:00, 2:15, 2:30, 2:45, 3:00, 3:30 (sweep). Out of respect for our volunteers, the course closes at 1:35 pm, at a pace of 14:06 min/mile.
Wave Start: The Half-Marathon start is done in waves to limit overcrowding on the course. Waves are self-seeded and start approximately every 90 seconds. Waves start fastest to slowest. Those needing more time or worried about keeping ahead of the rolling course closure time (14:06 mi pace) should start with WAVE 1 and keep to the left for the first mile.
