It's great to see it finishing in Istanbul again, and that idea is appealing, but I won't be entering again just yet. Two years in a row of that amount of planning and the fact that it takes a big chunk of my annual leave is just a bit too much.
I've not bothered to whack that into a route planner at all, but from first inspection it looks like it'll be longer than last year but the Alps will be mostly avoidable. Balkans will still feature heavily though and I have no idea how hard the terrain from CP3 to CP4 will be. It'll make for interesting dotwatching I'm sure!
