I recently had to reset my Garmin Edge 830 and since that all training load is very low. Everything is deemed recovery and this ride today only got a score of 14 on training load. It was almost 3 hours at 27km/h. This is less than my 5 min warmup on a treadmill.

I contacted Garmin but also wondered if other people hat this occur as well.
