Out the front door (Derbyshire) and up to John o Groats via a scenic route. Hopefully take about 7 days.
@benfan – there’s a link to a ride here that @richpips and his lad did last year in the break between lockdowns which is almost exactly what you describe:

@richpips on Twitter and IG as well.
A few years ago, I did a gravel route across Lancashire – started at Rochdale, finished at Arnside and went via a load of old packhorse trails, bits of Pennine Bridleway, canal towpath and so on. Was a really nice ride, quite a bit of industrial history within it. I’ve got a similar plan for a Trans-Cumbria which i almost did this year but then ended up doing a Lakeland Loop road ride of 145 miles in one day right around the Lake District which was a stunning day out, probably the best ride of 2020 for me.
I did a canal towpath loop too, the Cheshire Ring which is 100 miles – managed to pick a really nice weekday so it was quiet, the trails were dry and again, that was a lovely day out. Might try another one of those style things when I can.
