For me the CTC experience has been great!
I started riding with them just under 12 months ago. On my first ride, I did find the pace a little slower than I'd been used to (thinking it was easy....), but as a beginner, I'd done nowhere near the kind of distance we did that day of 50 miles (I was used to about 15) - and it proved hard work in the end going that distance, but everyone was friendly, supportive and I wasn't left behind at any point. I kept going back and that attitude (welcoming, supportive) has been consistent throughout, and after a few rides I joined up.
On occasion a ride can be a little slow, it all depends on who's leading, but there is the opportunity to split up the group for a faster or slower pace if necessary.
I've got access to two CTC groups on my doorstep and recently been going out with this other group. They draw a large crowd and split up into group rides based on speed. You choose which group you go in, and if the pace of the group is a little too much or too little, swap groups at the cafe stop.
With the CTC, I can go out every Saturday and Sunday and ride at least 40 miles (summer months 50-80), paying no more money than I've paid for my membership.
I would agree it does need an image boost and needs to be more dynamic if it's to survive. I'm 37, by the way, shave regularly and I'm stunningly handsome.
