Yep, what ton said is a very good day out in the Dark Peak.
Alternatively a slightly easier option, or if the weather is bad: ride west down the Colne Valley along the Huddersfield Narrow Canal (there’s a couple of gates but everyone just lifts bikes over them), turn left at Marsden (go up Old Mount Road not the A62) and then over towards Uppermill and down onto the Pennine Bridleway. That will take you pretty much all the way to Chapel with minimal road work and no tricky routefinding. The road bit out of Glossop is a bit crappy, but otherwise it should be a pretty good ride, that. It’s not hugely technical stuff, and you can make good progress, although most of the descents are good fun if you hit them fast and the scenery and whatnot is grand.
