The Chicagoland Half Marathon Series is comprised of 2 events; Byline Bank Chicago Spring Half Marathon and the HOKA ONE ONE Chicago Half Marathon. Both events are signature events produced by Life Time and their Chicago based production team.

Ambitious participants have the opportunity to be recognized for their outstanding athletic achievement in taking part in our two Chicago races with the 26.2 Challenge award.

The Chicagoland Half Marathon Series is limited to the first 2,000 individuals who register for both half marathon distance races. Competitive awards will be offered to the top three male and female finishers using combined scores from both events.


The 2021 Chicagoland Series Challenge will consist of the following events:

If you complete both Half Marathons, you will pick up your 3rd Medal at the finish festival of the 2021 HOKA ONE ONE Chicago Half Marathon.


  • Can I register for the events separately? 
    Yes, to be entered into the Series Challenge, you must register for both events using the same full name (no nicknames, middle names, etc.) and the same email address for each race. You will automatically be enrolled in the Challenge as long as your information matches for both races so it’s okay to register for the races separately.

  • How do I confirm I am in contention for the Series?
    So long as you are registered for both events, whether individually or through the Series registration link, you are in contention. We will post contention rosters periodically leading up to the event.
  • I registered for both events but was unable to attend the Spring event. Do I still get my 26.2 Challenge Finisher Medal?
    Only official finishers from both events will receive the 26.2 Challenge Finisher Medal. It does not suffice to simply be registered. Yes, we verify results for both events.
