Some of the other sites that I found useful when planning my ride (or subsequently). No guarantees from me that the information is useful to you or, indeed, accurate!
Sustrans website for Route 68 and the chance to buy their maps.
Cycle.Travel website – a good site for routing as an alternative to Komoot and also contains sections on each of the long distance routes including the Pennine Cycleway.
A report from Trevor of his trip in 2018. He camped and seemed to have made a lot more modifications to the route then me. He also seems more emotional!
Google will help you find many, many more accounts of people’s trips. My advice is to stop procrastinating around the planning, get the date booked and then start the ride! Good luck.
