Hi Dehorah, there are a few running clubs around newbury that I know of, Team Kennet which I think are more Track based! Compton Harriers and Tadley Runners which I believe are move Road and X country.
Sorry I have never run with any of them so can't help too much.
I know there is a group who run round Thatcham (where I live) but don't know any more details, I have just seen them out in the evening.
I am thinking about joining Compton Harriers in the next few weeks if my knee holds out! I have been struggling with a knee injury for a long time but am on the comeback trail. Planning on running Bayer 10km 29th May (Newbury) so need some motavation!
