I am very satisfied with Strava. However, not about displaying long activities among all other activities of your followers and sharing a long activity @Social Media.
For example, yesterday I cycled the touring version of the Amstel Gold Race. This took me about 8:45 hours.
If I look to and share my activity, the elapsed time is displayed there. This is 3 hours longer. So everyone thinks I cycled for 11:45 at a very slow pace. Why do you see the moving time on short routes and the elapsed time on long routes?
