I am looking at attempting this sooner than than later but as i live in Hove would rather start from Devils Dyke and do the double back to there, does it have to be a Winchester or Eastbourne start ?

Interesting question that; but i’d imagine it does need to be the same start/finish to go for offical recognition or the record attempt.

…just my opinion though, unsubstantiated!

Are you going for the record or just as a personal challenge?

If it’s the latter then start and finish where you want.

may have more info and Rory at Upgrade kind of manages it.

Its only for personal and maybe charity but still want a sub 24. i will try to contact Rory @ Upgrade then to see what the situation is.

as above if you ride it twice then it’s a double for your purposes – no one’s going to say ‘well, that doesn’t count do it again from Eastbourne’

Did this when I lived in Hove, and my original plan for the route was Hove – Winchester – Eastbourne – Hove.
But the two people who did it with me said that it was against the law, and we had to do Eastbourne – Winchester – Eastbourne. Which made it logistically more difficult for no good reason.
