CTC http://www.ctc.org.uk/local-groupsI wish there was a club like that around my way (Newcastle Upon Tyne). The lowest average they expect is 16mph. I can do this at a distance of 20 - 25 miles but do not know if I could do it for 50 - 60 miles which is the lowest distance they do
I'll live near you, I used to use the old Air Valley road to get used to distances and do short climbs off it in a loop and back down, East Morton, Silsden, Bradley etc FWIW I don't think your description of the ride is what I'd expect as a beginner.
