This is a bit bonkers, bear with me ...
A couple of years ago I ran The Ridgeway in chunks over a few weeks - it took about 7 episodes, distance varied from 8 to 18 miles. It was surprisingly lovely; I now have a mental picture of the whole of the trail, I know how it fits together, and the different types of terrain, and the fascinating evidence of history and pre-history along the way.
So, how about the Pennine Way. Like most of us I've walked bits, but I'd like to connect it all up. I live in Reading, so it's not within easy reach. I had some spousal car support for the Ridgeway, but that's not going to happen when I go up north for the occasional weekend. I can do an out and back to the car each time (thus doing it twice), or I can devise circular routes but obvs only a bit of each circle will be miles ticked off the route. It's doable, but will take a while (two or three years of odd days or weekends here and there, and I can probably give myself a leg-up by taking a week to do a long section at some point).
What would be really handy would be sections where you can leave the car, do a chunk - whether a single day or more - and then get back by public transport.
Any ideas?
