Bank of America Chicago Marathon

TCS has been the official technology consulting partner for the Chicago Marathon since 2010 and is the creator of the official race app for the event. The app features all race-related information – including unlimited runner tracking, race results, elite athlete bios, custom digital cheer cards, and more. Runners enjoy the support of 1.7 million spectators as they run through 29 neighborhoods. 

“I'd like to thank you for the amazing experience at the race and all the support from TCS. The [experience] was absolutely the best race support I've ever had. We had a really great time and I just want you to know how much fun it was. Thank you so much!”

--Team TCS Runner, 2019


  • In 2019, the official race app, created by TCS, had more than 256,000 downloads, five times more than the number of event participants.
