Cheers Shaun. Chapeau for doing it on fixed !
I think sleep deprivation is the biggest challenge with brevet-porkers. You start the weekend early on Saturday with the BC start and then don't get to bed again until well after midnight. So, by the time you line up at Poole on Sunday, you're already badly sleep-deprived and you then have to go right through another night. I was hallucinating the first time I did it.
It's so challenging, and there's so little reward except for the knowledge that you were up to it, that I don't think many people have wanted to ride it again, but I'd like to get some names and dates just to find out more.
I've got as far as researching domain names though and the leading contender is currently: brevet-porkers.fun ... how inappropriate.
