Although I've decided not to attempt this one - I'm very interested in what kind of routing and climbing those who are come up with.
Obviously the racers won't want to share their secrets, but anyone else just aiming at a finish - even just in outline.
I did a *very* rough sketch from CP1 through to Cortina just beyond CP3, and came out to round 950km with around 21,000m of climbing. That was not much more than a RideWithGPS auto-route, which is clearly not something you'd actually use without serious research and refinement. I suspect the auto-route version is shorter, and that climbing might reduce a bit at the expense of extra distance. Of course I'm also trusting RWGPS measurements too - although we use it a lot here in SA, and distance and climbing come our reasonably close to what a Garmin reports on the actual ride. Climbing is often estimated on the high side by RWGPS though.
Just an interested by-stander really - although I doubt that the organizers will make 2017 any easier, so it's definitely interesting to see how people map this one with an eye to the next.
Edit - to me how you approach/break down this section seems to be a key element of the challenge for this one, hence the interest. For me, the above could easily represent 4 days of riding with maybe 5,000m+ per day. Of course it wouldn't even out like that in practice, there'd be a couple of very heavy days in the middle with more climbing and a lot less distance.
