RE: know multiple routes "out".
I am not sure how it is in GB,
but I know that Canada can be crossed from east to west by water without walking more then 13 miles.
The U.S. can be traversed by water with only 25 miles walking.
In the old days the waterways were the best means of travel. Both England and the U.S. were laced with canal systems.
One should also scout out the rail system. Rail is built on no more than a 3% grade and is almost always above flood stage. If one is on foot, following the rail bed in rural areas avoids the road system and many prying eyes that are focused on them.
