Bought a hybrid in May and started from scratch. Furthest so far is the London to Windsor ride which came in at 57 miles and took about 4.5hrs (ie. quite slow).
The hybrid is definitely easier when I change onto the skinny tyres although I only really do that if i'm going to do a longish road-only ride.
Thinking about the Bath-Clew Valley ride in a couple of weeks to close out the season; another 50 miler. TBH I've not really cycled as much as i'd have liked so progress is slow, but these intermittent organised rides do keep my motivation up. Dark evenings kind of rule out riding in the week which is a shame.
