Prompted by a comment on a recent question about weight loss I started to wonder: for people who ride bikes at least sometimes, what's the distribution of maximum distances? This has also come up in discussions among distance riders about cycling infrastructure for mass use. Or, to put it another way, how abnormal are those of us who like to ride a long way?
Ideally this would be a survey of the maximum distance people have ridden/typically ride, but as that's unlikely, it's be interested to see anything that sheds light on the question. While I'm in the UK, an international picture would be more, not less, interesting.
I've seen some UK stats from cyclinguk and some walking & cycling UK national data, but they are either based on acceptable commuting distances or don't capture variation.
