I recently started biking again. Last time I biked regularly, I used a little bike computer that recorded my speed, length of trip, etc.. This time, I'm using an app for my Android phone called MapMyRide.
I'm really digging this free app, and thought I'd share the love. It uses the GPS on my phone to auto-map my route, appreciates the elevation and lets me know how far I went, how long it took, my average speed, calories burned and other cool stats like that.
So if you're biking, you've got to try this app. If you know of any other good biking apps, leave a comment.
