# Import participant data

* Keep the participant list up-to-date and prevent mistakes.
* Use your system to add tracking devices (GPS trackers, transponders, decoders, track boxes) to specific athletes. Synchronize the tracking devices with RACEMAP.
* Manage participant information such as name, race number, key, status (DNF, DSQ, DNS), start- and finish time, and much more.
