Chi Town Half Marathon & 10K 2027

The Chi Town Half Marathon & 10K is a Chicago race series with two distances: a half marathon and a 10K. Both routes are USATF certified, and the race is built around the city’s lakefront, with runners moving through Lincoln Park and along Lake Michigan. The setup is practical for everyday runners, with aid stations and plenty of toilets along the course. At the finish, the race leans into its Chicago identity with Portillo’s and Chicago-inspired finisher medals, and the series has already marked a decade of running in the city.
