Yep, there’s the Nancies from Bollington: http://www.whitenancy.co.uk/index.html
And Macc Wheelers have a night ride too. I’ve been out with thema couple of times but it was five years ago or so. They’re a nice enough bunch but a bit quick for me.
Then there are quite a few informal groups. Me and a few mates are one of them but over the last couple of years we’ve stopped getting out as much. One of the main reasons is that I tend to organise things and recently I’ve been working away midweek quite a bit and others have moved, changed jobs, had kids etc. We get out about every 6 weeks or so now 😥
