I'm not certain of this but I think google maps has a tracking function that will record your routes and you can reverse them. The other thing maps does is saves your recent searches so if you entered a search for the location you want to go back to, if you're somewhere and want to go back to the location you were at, just enter the drop down list of places you've been and select it. It will calculate the route if you allow your phone to find your current location.
