I went with them once last year on a saturday 9am ride,good bunch of lads, but the ride was a bit boring tbh-a lot of canal and road. As Lee said though i guess it depends who leads it- the ride I went on was led by a cyclocross guy
I live in stourbridge and there’s some decent trails if you know where to look. County lane Norton is a good starting point and either go out towards blakedown or towards the roman road and the rugby club. Good mix of bridleways and woodland which you can easily link up for 10k or so
