Road or off road?
I used to live in Woolhampton. Best off road options are probably to head north to the Kennet and use the towpath to head east or west pretty easily. West takes you to Greenham Common area, then out into west Berkshire. North of the Kennet takes you up towards Upper Bucklebury – heading along towards Cold Ash from there gives you various bits of singletrack.
Or, Tadley has a new skatepark – it is quite fun!
Volunteering? We used to get the “friends of AWE” magazine, which had lots of community reports in it. I’m sure that will have lots of options to give you a healthy glow 😀
