Well ive goofed a bit. I had assumed (incorrectly) that 400 on a York Arrow would suffice for pre-registration, given that it had an ACP number against it in my results. Found out yesterday that was wrong and I didnt do any other BRM events last year. Calendar events yes but not so much as a single BRM 200. I will therefore have to take my chances come 31st May onwards.
Given that Ive arranged travel and accomodation my plan B will be to do some other cycling in France at the same time. One possibility is to finally nail my Brevet 25,000 by doing a 1300km event, maybe down towards Bordeaux and back.
Of course now having thought about it Im actually more excited about the alternative than PBP and spent lots of yesteray evening planning a nice route.
