I miss having the ability to create folders for various activities like in Training Center, then drag new activities into separate folders and able to see summaries for each of the folders. I used to have an Edge 800 that I used for ALL my activities, and now use an Edge 820.
I have tried several ways to do this in Garmin Connect, but it isn't as flexible on activity labeling/tagging and displaying summaries. I don't like having to edit each activity separately and then use a filter. Just way too much effort in comparison.
The folder view allowed me to see summary stats week by week as I progress in my training and also compare year to year. Training Center works in this area and Garmin Connect falls flat.
