Welcome to Crossfit Defined Endurance

CFE @ CFD is the endurance programming and resource site for Crossfit Defined. We’re located in Chicago’s Lakeview neighborhood. Throughout the late-spring, summer and fall, the Endurance workouts are programmed on this website for Tuesday, Thursday, and Sunday. We meet as a group on Thursdays (Intervals) and Sundays (Indoor Endurance at LS). Tuesday programming is “on your own.”

The written program is intended to guide you to a fall-race goal. Even though we do not meet for all the workouts, you are encourage to do them on your own.

We’re dedicated to improving performance, fitness and endurance sports potential. We will help you through every step of your endurance training.
