It's going to be a good turnout this Sunday - 10 or more, but it is normally more like 3 - 6 including me.
Obviously there are a lot of CC members in the London area and they can get quite a few people to turn out for their forum rides.
I'm quite lucky here in having Leeds, Greater Manchester, Bradford, Huddersfield, Burnley, Preston, Halifax etc. within a 30 mile radius and people are willing to travel that far. I suppose that I've built up a bit of a core group now, and then get others coming along to join in.
For some reason, I found it much harder to get people to turn out for the 2 rides I organised last year from Meriden which is between Birmingham and Coventry, with Leicester, Wolverhampton and lots of other towns and cities not too far away. A bit mystifying that! Totallyfixed came on one of those rides and has been having a bit more success in scenic undulating
Rutland, so perhaps it was just that people didn't find my flattish Midlands routes quite as exciting as my hilly Yorkshire/Lancashire ones!
Obviously, the population of Scotland is a lot smaller than that of England so you naturally won't have as many CCers up there, but Aberdeen is a fairly big city, and Dundee is about 50 miles away so I'd have thought that you should have enough CC members in your area to make it worth organising something.
I suggest that you send a PM to Nebulous and Milemuncher if they don't respond to/spot this thread. They might know other CC members up there.
