Know someone running the 2025 Bank of America Chicago Marathon and want to see how they’re doing?

For the spectators hoping to catch a glimpse of a friend or family member along the 26.2-mile route, finding where they’re at can seem daunting as thousands of runners race through miles of city streets.

And those watching from home, hoping to see their loved one complete the race, might wonder when their loved one is nearing the finish line.

The good news is that spectators and supporters can track runners live.

Here’s how:

How to track a runner

Runner tracking is available via the marathon’s mobile app.

The app includes “unlimited live race day runner tracking,” according to organizers.

Spectators can even submit a digital cheer through the app for a chance to have their message displayed on the course as their participant goes by.

This year’s app also includes 11 “leaderboards,” which will allow users to find race leaders across all tracked categories, from the professional athlete field to the open field — all in real time.

Details on how to download the app can be found here.

What time does the Chicago Marathon start and end?

The Chicago Marathon is scheduled to step off just after 7 a.m. CT on Oct. 12 in Chicago’s Grant Park, though runners will take off in “waves” so their start times may differ.
