The CTC also have regional/area groups that meet up (usually at weekends) for leisure/touring rides. You don't need to be a member to go on a ride with them - they only expect you to join if you're going to be a regular. Try a search for a club in your area. They are also heavily involved in York Cycle Show/Rally every year. This is a kind of bike festival with camping, CTC organised social rides, audaxes, trade stands, bike test riding (including folders, recumbents, 'special' bikes, tandems, trikes etc, if you've ever fancied a go on one) vintage cycling films, grass track racing and cycle polo to watch.
