Strava gets a bad rep because of the segment chasing users. But if you forget the leaderboard strava is the most complete app out there. It provides options to track mileage on different bikes, year to date mileage, average week rides and mileage etc.

If you don't like racing you can mark your rides private and your name won't appear on the segments but still can track your progress on any given segment/route.
Strava does have the option to create routes but I believe RidewithGPS does a better job at this

I've used Strava, RidewithGPS and MMR and compared with my buddy's Garmin edge 810 with built in altimeter. Strava by far is the most acurate of the 3 when it comes to real altitude and distance.

Ever forgot your phone or gps unit running and got on the car and drove away? Strava is the only app I'm aware of that allows you to crop the ride.

It's simple, clean and the app/website interaction work flawlessly. And no annoying ads like MMR.
