I don't really care for a lot of rules, but the fleche is one of my favorite of all rides. I can't even count how many I have done. I get to ride a little...eat a little, ride some more...eat some more...eat a little more...what could make for a better day on the bike? Somehow, I always end up at the finish line at near enough to what ever time I'm supposed to be there. There is so much extra time built into fleches that it isn't funny. Unless you design a route that is much longer or harder than required, then that is your fault.
All the fussing about the 22hr control is a waste of time IMHO. Just go out, ride your bike to some great restaurants and adventures! Heck , one year we had a control at an Indian casino. Partook of a pretty good buffet,played some blackjack and turned in some $1 chips as proof of our arrival at the control. Don't forget, this is supposed to be fun!!!!!
