Hi – I’d certainly recommend Bigfoot, although I used to be the Chairperson so I probably would 😉
There are regular weekday rides of various grades up on the website (you’ll need lights of course) but you might want to start off with an Intro ride which are run about once a month especially to welcome lapsed brothers back into the fold (and new riders)… Get in touch via the Contact page if you’d like to know more:

If you can get out two or three times a week the easier it’ll be though, it’s just a shame that we’ve not got much local riding, although you’re welcome to try out this loop I was shown:

It’s ideal if you’re looking for some riding from the front door, it’s based on Bridle ways too so it’s all legit. Good luck with getting your mojo back!
Andrew.
