There’s a few (well, a couple certainly) from Worcester who get out with the Ashton MTB club with reasonable regularity.

Most week day rides are within a 30 minute drive from Droitwich anyway. Though in fairness, this may just be on the cusp of how far you would travel to join a club, so you might be as well off starting your own.
Worthwhile asking in LBS’s possibly? I don’t know what shops there are in Droitwich, but there’s Worcester Cycle Centre in Worcester (funny that!) that might be worth popping into and asking if they know of anything closer to you. WCC is a pretty good shop anyway, discounts given to ashton MTB members anyway!
