The Kiprun 500 and 900 GPS watches do not have a built-in barometer. Because of this, they cannot support structured workouts that have Effort Pace or Power. These watches also do not support Strength mode.
When trying to sync a workout to these watches, you may receive the message: "Workout not compatible with watch. Update watch firmware or sync to a compatible device."
To sync the workout successfully, please check if the workout is a Strength workout or includes Effort Pace or Power as the intensity type. If it does, please edit the workout to remove these details and then try syncing with your watch again.
