So, if I do the Hell Week in Provence, pay and register for PBP, go to the start to get my number, etc., then I can start whenever I want (avoiding the official start line); I can then ignore all the controls and the finish line and just ride straight back to Paris. I can't see that anybody would have a problem with that, correct? Even if somebody decides to disqualify me halfway through for not stopping at the controls and having an empty brevet card, they still can't stop me from riding on the open roads, so that will make no difference to me.
I don't collect medals or need to see my name in a list of finishers; I only collect experiences and memories, and I'll be equally as proud of a self-supported route completion (including doing it in the traditional way by starting and finishing in central Paris) as I would an official finish time. Plus, I'll be making it easier for other riders by not clogging up the controls despite taking a start place.
