@ADidier Concept2 could connect to Suunto if they wanted to, like they do with others:
If you use a fitness platform like Strava or Garmin Connect and want to see your Concept2 workouts in there, the easiest way is to use ErgData to send your workouts to the Concept2 Online Logbook. You can then connect your Online Logbook account to send your workouts automatically to several different platforms, including Strava, Garmin Connect, Training Peaks, CrewLAB, FitBit and Final Surge.
