Hey, i've just got back from john ogroats, i went up the east cost through edinburugh and it's flat, the only hills are before dunbeath 20% down then a 20% climb, the worse hills ive done so far where around slaidburn, and from what everyone's been telling my devon is the hardest because of the continous rolling hills.
How are you going through scotland, because after edinburugh i went along the a9 past aviemore to inverness that way but it was horrible so if you're going that way, go through braemar, cock bridge, and up that way, it's alot hillier but it's worth it.
In edinburgh i stayed in a place called bilston, it's awesome there, it's a protest site against a road, so theyve built tree houses and tunnels, if you havnt already prebooked accomodation stay there!
