Not a randonneur myself (or at least not yet), I've always wondered about that last 25km rule, it having to be ridden btwn the 22nd and 24th hours. Why is that? I understand that a fleche isn't a race, but still - if the riders can, and want to, ride it faster, why not allow that? That rule actually might discourage some racer/randonneur crossovers who'd like to ride it like an extended team time trial. Just curious...
