Spanner Man
Theres loads! I used to live in Wallingford a few years back and the square of land between Wallingford-Goring-Reading-High Wycombe (i.e the south Chilterns) is rife with decent trails, all of which are rideable
Favourites of mine were all the stuff round Nettlebed (Deadman’s Lane – spooky at dusk!), Stoke Row and Woodcote – brilliant!
Get yourself a 1:25K OS map and go and explore, or, failing that, get yourself along to one of Trail Break’s evening or weekend orienteering events which all take place in the area around Reading. see web site.
Have fun – Im jealous as I used to love it down there :-(
