I will ride 4,000 miles this year using a combination of Map My Ride and the Google Maps App with the Cycling layer. I keep coming back for one more test of Ride With GPS, primarily because I have cycling buddies who have carefully groomed Ride with GPS routes that I would like to use. However: Four bucks a week is insane. A forty week cycling season means that this single app would cost me as much per year as two months of my entire cellular service. Save your money.
Use Google Maps with the cycling layer, and log your trips with Strava or MapMyRide.
