One of Chicago’s few remaining independently-owned large races, the 14th 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 (YES! We’re back inside this year!) before tackling wind & weather along a lakefront course which features splits every 5km. A must for anyone preparing for a spring marathon, or just resolving to stay fit in the new year.

The 2023 event will return in-person to Soldier Field, and we will have the (heated) United Club for both pre- and post-race!

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
