@wkoestsch Strava tells you pretty much the same data for your personal rides, but you can also set up a heart rate monitor for it and it will calculate even more data with it like Suffer Score. However, I know it's extremely popular in the bicycling community in the US, there are many cycling computers that are programmed to automatically upload to Strava. The one thing I really enjoy about it is the social aspects, especially the segments. There are segments people create around most cities and a leader board is formed based on average speed. You can filter the leaderboard to friends/age/weight/gender/etc. Pretty cool!
