There are apps that allow you to download maps ahead of time so that you can track your ride without WIFI or cell service. I use one for hiking called MotionX GPS. It's not free, but it's only a few dollars to buy it outright, so it's not a huge investment. It seems to work very well.
EDIT: Downloading the maps ahead of time isn't a requirement, the GPS will still work, but if you get lost and want to use the GPS as a map you won't be able to do it if you haven't downloaded them already.
