Many years ago after a big operation on my spine I joined a swimming class - it was actually with some pensioners, but it was perfect as I just wanted a gentle swim to get back some mobility. I'd started to get a little stronger and my swimming stroke was improving so it was suggested I join a swimming club as I was not a bad swimmer.
There are sports with rules. Cycle sport has a lot, some of which would baffle Aristotle. Cycle touring, on the other hand, is anarchic. No, tourers don't make up the rules of the road; but cycle-touring can be what you want it to be.
