Strava has a seamless interface with my Garmin Fenix 3 and most of my running friends use it. It makes it easy to keep
in touch. I even am able to follow the top trail runners and Olympic athletes. The only small improvement would be to improve the swimming. It should have 50m increments, not 100m for manual entry.
