I've got all day tomorrow in the peak district and could do anything.
I've not got the legs for the 57 miler I had planned
Any suggestions?
My more recent long peaks rides are hathersage- moor- hope quarry ( cavedale if I have the legs)- broken road climb then over and up to Jacob's ladder- Casleton- then back.
Since my wee one was born I don't get to get up the the peaks proper much and tend to do a variation on the above. Prior to that I'd be up most weekends for 25 miles or similar.
Suggestions welcome

You lucky person 🙂 (from a southern resident).
I don't have loads and loads of different places I've ridden but I think a couple of my very favourite rides of all the time I've been riding have been around Edale. I think it's partly because it's the first place I ever rode somewhere really rough (back when flex stems were a thing) and I've really positive memories of good trips there, met great people on the trails etc and introduced my boys to it a year or two back round this loop. I'm sure someone could do better but we were constrained by starting somewhere that my wife could walk the dog from as well.

I enjoyed doing this a few weeks back. Not 40 miles, but felt like a big half-day out.

Or this from a couple of years back. Rather more than 40 miles, but options to shorten.

Could do something on the Eastern Moors if you've not been that way recently - Stanage, Blacka Hill are good. I think that is the best aspect of the Peak, looking Westwards from that general area.
Cut Gate always a reliable option.
Ladybower loop, extending to Cut Gate (and back) one end and Cavedale the other? Possibly adding the Hayfield/Jacob's Ladder loop on as well?
Maybe too similar to your usual though?
Peak, peak, peak. Singular. Peaks is meaningless waffle.
Anyway, back to the question...
Do the 9 best Peak descents? ( They're not, but it'll get you on a different route....)

it's not the three peaks.
