Then, simply enter the name or preferably, the bib number, of whichever racer you’re looking for. You can find out where they are on the interactive map as well as receive notifications when they have crossed certain timing mats.
The app has a feature called “Wayfinder” for spectator tracking, and the “TCS Marathon Boost” allows supporters to send heart-warming messages on the huge screen monitors the appear throughout the course.
In order for the app to work effectively, your runner must ensure they have GPS switched on their device participating in the race.
