How does this sound?
Friday PM: train to Derby, then 5-mile completely flat, off-road-but-all-tarmac S*str*ns path to campsite
here. Pitch tent.
Friday Evening 'bent ramble - some off-road, mostly flat, in the Trent Valley to Willington to Etwall to Mickleover; drinks in one of the many many many real-ale emporia in Derby. Dinner at a curry-house or Chinese. (OR see if either of the Elvaston/Thulston pubs - near the campsite - do an evening meal.) (About 40km round trip, but could easily be cut down to suit.)
Saturday: The Big One. Road-route from Derby to Wirksworth (with a bit of A6), then up the
HILL to Middleton Top. High Peak Trail to Parsley Hay (100% flat - railway line was built for horse-powered operation). Tissington Trail to Ashbourne (Has to be experienced on a 'bent. Drops 200m in 20km, with terrified pedestrians and other cyclists leaping for the verges. Bring an airzound. Or two.) Late Lunch stop in Ashbourne. Minor road route back to Derby. 80km round trip, with another 8km each way from campsite to Derby and back.
Sunday: pack up and leave.

I haven't chosen a date. I'm waiting for my knee to be x-rayed before I know what I can commit to.
