I use Garmin Connect and Strava, along with Sporttracks (ST). ST. is great for all my courses, and helps creating new ones with the mileage points. Also mileages on all the bikes and when chain maintenance is due. Garmin Connect is only useful for my wife, so she can find me if an emergency arises. I'm mostly interested in mileage, altitude , and Heart Rate data. Strava for friends use.KB.
