Is this my future?

If jogging causes me niggling pains I may have to think about cycling. But where do you go? I know you can go along the canal towpath, but it runs out at Dochgarroch, some six miles away, and I've done it many times either running or cycling. I'll need to brush up on dedicated cycle tracks but I don't know how many there are.
   I've just had a wee look and it seems that there are not that many. I see recommended routes which are on public roads. It's not what I had in mind. I don't think that cycle routes have been a priority here.
