Presenting Sponsor

Chicago’s Hometown Race Welcome’s MY FIT KEY as presenting sponsor.

MY FIT KEY (MFK) is proud to be the Presenting Sponsor and Official Genetics Testing Laboratory of the Chicago Half Marathon and 5K.  MY FIT KEY performs DNA Testing for Athletes – to identify specific genetic traits to improve training and results. By surveying an athlete’s current fitness status and goals and integrating that information with genetic results backed by the latest in research and exercise physiology, MFK delivers actionable, relevant training recommendations.

MFK tests will be available at the Healthy Way of Life Expo or online. With a simple DNA swab, athletes can choose from three testing level options to fit their performance needs; Elite, Warrior or Sport, as well as a cardiac risk panel. Results are available through an online portal within 2-3 weeks and include important information about an athlete’s recovery time, his/her risk of soft tissue injury, sensitivity to Ibuprofen – and other genetic insights.  To learn more about MFK and how to unlock training and performance potential through DNA Testing for Athletes visit
