Quick hour – 1. 5 hour spin from Belper with some lovely bits on, nice scenery too. Do it starting at Belper bridge and crossing the river up to Belper lane end. Nice beer at Farnah Green if you have time to stop.

I have a couple of nice 50 mile and 100 mile routes starting from Matlock train station, am on my phone right now, will try and remember to post them up. There are a bunch of good rides up the valley that way. You can also do train to Matlock then nice trails back to Belper.
Some great riding round Ambergate and Cromford, 3 and 7 miles up the a6, a bit hard to describe / navigate, but well worth the hassle of finding it.
Also, Fresh Basil deli for big slices of great cake (very good bakewell pudding too), George and Dragon for nice beer, and the Ritz Cinema is the best cinema I’ve ever been to, although unfortunately you have to book well in advance for most things.
