Dr. Blomgren explains that even Chicago's cold winter weather doesn't have to stop runners from running outdoors. Dr. Blomgren, a sports medicine specialist at Midwest Orthopaedics at Rush, was featured on NBC5's morning show to discuss the best clothing materials to wear and the importance of stable shoes with traction when running in snow. Dr. Blomgren also recommends a good warm up and stretching to prepare the major muscle groups for running in the cold.
