As many as you'd like.
We know planning a trip takes time and effort and you sometimes have numerous versions of your trip plan, that's why with your RoutePerfect account you can save an unlimited number of trips and and trip versions and then go back and compare.
Every time you click the 'Save' button we will save your trip as a brand new trip instead of running over the last one.
Your trips will be save to 'My Trips' page, to learn more about where to find your trips read: View Trip
