Where will you be living, Dursley?
I live Stroud way, i have several doorstep ride options:
Loop with 10miles of road at start gets me to Birdlip, into Cranham woods, Painswick Beacon, Edge, Standish (can then add Coaley Peak, Rodborogh Fort) for 40 miles of riding.
Or, set off along canal to access Standish Woods & Edge, & or Coaley Peak via Penn Woods.
Can loop round from Coaley Point to Dursley too.
Can ride loops from Nailsworth too, but i’m still exploring that side.
Can be / is a mud bath in winter.
Bigfoot is a very active local MTB club.
Various MTB shops: Delta in Dursley, Noahs in Brimscombe, Black 8 in Woodchester with a Wed pm ride, Cycle Tech in Ebley, Bike Works in South Woodchester.
Plenty of pretty small hills with tough straight up climbs.
Welcome & enjoy.
