TBH - I've always felt that YACF celebrates the finest in pedantry and unnecessary grumpiness... characteristics you rarely encounter when we're actually riding!
You say that, but...
My first long brevet was John's National 400 in 2018. I remember on the way back from Aberystwyth, as the climb gradually became a fast A-road flat, we caught up with this AUK veteran (you can tell by the amount of clutter on the bike), who as soon as saw we were approaching, made a hell of an effort to drop us... by then it was getting dark and safety was in numbers, unless you are of a grumpy nature of course.
Eventually, he lost his jacket a mile to the finish and that was duly picked up and returned to him... didn't seem particularly grateful either...
So there...
