If you’re in Great Lumley, you could easily head up the C2C from Chester, then round Beamish, Causey, Waldridge fell etc riding from the door. Or head for Finchale Abbey then Durham, on to Lanchester valley way (or whatever its called) up to Consett then back down the C2C- not technical but a nice ride out.
Could possibly show you round Sunday, but Im at a party Saturday night so will not be in tip top shape Sun 😳
