Yea, Strava is probably the easiest way to go for logging and viewing stats. I really like to geek out with the data though. Personally I use this
Bike Computer app. You can backup all of your recorded tracks to a SQLite database, or individually as a GPX for upload to Strava.
If you just want to see a radius on a map of your known mileage there are sites like this:

Also, if you can export your rides into a merged GPX there are really cool sites like this for making custom heat maps:
