Bank of america chicago marathon tracking

On 10 October 2026, the Bank of America Chicago Marathon officially launched its updated digital tracking platform, designed to provide spectators and remote followers with real-time data for the 2026 race. The enhanced system allows users to track an unlimited number of participants simultaneously by entering their bib numbers or names into the official event application. The platform provides split times at every 5-kilometer mark, as well as at the halfway point, ensuring that supporters can monitor the progress of runners across the 26.2-mile course with high precision. In addition to basic timing, the 2026 update includes an interactive map feature that estimates a runner's current location based on their pace, helping spectators plan their viewing spots along the city streets. Organizers emphasized that this year’s tracking infrastructure has been bolstered to handle the high volume of traffic expected on race day, ensuring seamless updates for global audiences. The tracking service is fully integrated with the event’s social media feeds, allowing users to share milestone updates directly from the application.
