Are there statistics on cycling trip distances? 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 &amp; cycling UK national data, but they are either based on acceptable commuting distances or don't capture variation.
Here's an article focusing on some of the most active cycling cities around the world, and this is reporting averages, not maxima. The source data they link to at Strava isn't available to me (redirects to the Strava login page, and I don't have a Strava login).

The data is probably biased towards more serious cyclists--I'd be surprised if the average commuter in Amsterdam is bothering to log in to Strava every time they go out.
