The 2026 Bank of America Chicago Marathon is taking place on Sunday and thousands are participating in the event. The marathon organizers have made it easy to track a runner through the Chicago course. "Unlimited live race day runner tracking" is available via the ChiMarathon app, which can be downloaded in Google Play and in the Apple app store, according to NBC Chicago News.
To add registered participants to their tracking list, users can search their name and add them to their favorites. Users can track up to 20 runners through the app, which also includes an interactive course map, a schedule of events and race photos. The app also features an interactive course map and participant bib info, organizers said. More details can be found here.
