Experience Chicago’s Original Winter Half Marathon at the 15th Annual F^3 Lake Half Marathon & 5k!

As one of the few independently-owned large races in Chicago, the F^3 Lake Half Marathon & 5k has become a beloved event in the Chicagoland running community. Every year, thousands of runners gather in the warmth of Soldier Field’s United Club before braving the wind and weather along the lakefront course.

The CES Winter Warriors training program is already underway. As always, CES gives you the guidance, coaching, and motivation needed to achieve your fitness goals – no matter if that goal is to complete your first 5K, or to set a personal record in an Ironman Triathlon. Others simply hand their athletes the same schedule year after year and tell them to follow the person in front of them. They take an individualized approach to understanding your definition of achievement and then coach you every step of the way. Join CES and they’ll bring out the best endurance athlete in you.  To learn more about Chicago Endurance Sports and the wide variety of training programs they offer, visit
