I've just emailed Strava with the feedback they'd requested as to why I wanted my account deleted:
There's two things which led to this decision, both cycle related.
The first is that marking a clubrun etc as private removes segment performance data, effectively making the analysis no different to Garmin Connect (which my Garmin will automatically sync to)
The second is a moral objection to the site in allowing inner city segments which, in London at the very least, encourages people to ride in a manner which is inconsiderate of other road users. I'm not a cycle campaigner by any means but I do think the world would be a better place if competition was kept off some roads.
For the record though, as a part time runner I did really like the analysis that your site provides on a km by km basis. That's a feature I'm yet to find in such a clear concise manner on any other program.
