Hi Joffey,
Sounds like I'm in a similar position to you. 50 miles @ 15mph is about my ideal ride. I've long toyed with the idea of joining a local club, but not sure how I'd get on with the "regimentation" and the longer distances.
If you ever fancy getting together for the occasional ride then please give me a shout, I'd be more than happy to link up with you. There's a lot of other Yorkies on this forum, so perhaps we can get some more peeps interested?
