This minimum distance will enable me to work out a ball park figure for the total cost in fuel as well, which enables me to come up with a loose budget for the trip, which hopefully won't be horribly expensive. As it stands right now just to travel directly as per the list to where I want to go without any running around within towns or off the main route to sight see it is going to be 20,250.9 kilometres (12,583.3 miles), so should be great. Obviously this is just guidance though as who knows what route changes may become interesting once under way.
