In reply to minimike:
I did exactly that in, I think, 2017 or 18. Despite starting in torrential rain on Ingleborough and ending in a thunderstorm in Whernside it was a cracking day. Took me I think 9 hours 20 including a coffee stop at Horton after Ingleborough and a leisurely lunch stop at Ribblehead (great pie in the pub).
Not included in the 9 hours 20 is the following, which took precisely 50 minutes:
Left the pub after lunch, started running, and a little voice said to me where is your car key. Don't be silly I said. But the voice said it again, so I took off my running pack and behold car key was not there.
Went back into the pub. No key. Various emergency schemes now flying pointlessly round my head. Phoned the pub in Horton where I had coffee. Peugeot key? said the lovely man. Yes, I said, I will love you for ever.
Except the key is 6 miles away ... Bar staff confer ... Tom'll take you, said somebody, and Tom emerged from the kitchen wiping his hands, god bless him for ever, ran me down to Horton in his car, brought me back to Ribblehead, and off I went again.
(In retrospect if there hadn't been Tom I could surely have hitched perfectly safely)
So don't leave your car key in a pub when you stop for coffee. (Ever since then I've kept my car key in a front pocket where I can check by feel while running).
