How to switch the Starting Point and Ending Point?

I went on a Back Packing trip and I recorded the route from the place where we camped back to our Car where we parked. Is there anyway how I can Start the Starting Point where I Ended at the Ending Point? The reason why I want to do this because lots of people like to go Back Packing on this trail but they get loss very easily and trying to make a route so people can find there way easier
