I downloaded the Strava app for my new phone and gave it a try today. I found it to be very intuitive and easy to use. I'm used to using my Garmin 305 and Map My Ride. I found this to be easier. One concern I had was the phone's ability to receive a signal while in my seat pack. It did and there were no gaps in info. I was also concerned with the app's effect on battery life. After my 45 minute ride I saw no discernible drain in the battery. What it'd do on a 50 mile ride remains to be seen. The ease of posting was impressive as well. I can see myself just using the Garmin as a speedo since I take my phone with me any how for emergencies. I have also downloaded the MapMyRide app and will try it next time.
