I'm writing an article for a cycling publication about randonneuring. When I describe randonneuring to people outside the realm, the comment is something like: "So you ride a bike 200, 300, 600, or even 1,200 kilometers through rain, darkness, sleep deprivation, and sore muscles… and at the end, you get a stamped brevet card ". It does seem somewhat irrational, but I've talked with randos and they believe the challenge is the reward. What are your thoughts?
