The TCS NYC Marathon is this Sunday and now you can support your running friends and family by tracking them mile-after-mile-after-mile through all 5 boroughs using the official TCS NYC Marathon App.
The way it works is quite simple yet very accurate. Each runner has a small electronic chip on their running bib (where the number is) that is scanned by special receivers at each mile marker. This allows the App to know exactly when the runner crosses a mile marker, and the overall time the runner is at.
