Interesting.
I live in the area and know every bit of the route. Always surprises me how many I meet walking this that don't actually have a clue.
I get asked for directions all the time. "Is it much further?" Usually asked on the Whernside ascent.
I tend to look at their kit (or lack of) and genuinely worry.
Good luck with your endeavors
Just occurred to me you need to get these into the cafe at Horton. I'm not sure what competition you might have. But that is the first part they struggle with. Which way to go in Horton?
