As a slower rider, I've also always had sympathy for the faster types who, in the end, joined a club because of the fitness and satisfaction gained from blatting along in a group at 20mph. So they end up relying on someone else to provide the more sedate ride for newbies, or else quite often losing their days out. Now of course, with no provision for newer riders, the club dies in the long term. But there has to be balance somewhere.
My first ever club ride was with the Altrincham Ravens. My brother, who was equally inexperienced, took me along. They were very good, and ended up pushing us a fair way of the 70 miles they were doing that day, eventually leaving us near home to make our own ways back, when their own route home headed off another way. But I think we affected their day out.
That wasn't why I ended up joining another club, and I was grateful for their patience.
