The TREK Antwerp Marathon App, provided by Sportunity, is used to enhance the experience for both runners and supporters. This app can be downloaded for free from the Google Play Store (Android) and the App Store (iOS).
The app offers LiveTracking, allowing runners to be followed live throughout the event. Those who prefer not to be tracked during the race can set their profile to private when registering in the app. In addition, the app provides users with essential event details and live updates.
Below you will find some frequently asked questions about using the app:
The app validates your bib number based on your date of birth. This must match the date of birth in your race registration. If your date of birth is unknown, the app will validate based on your first and last name.
No, that’s not necessary. The app uses intermediate timing points based on your bib number and calculates your average speed. Only if GPS tracking is enabled will your phone be required.
