I think that there is a new road that will be tarmaced for the first time.
It's almost certainly the Col de Sarennes road.
This had a reasonable tarmac surface when I rode it in 1998 (apart from drainage channels at intervals across the first part of the descent), and what there is on google maps/panoramio makes it look reasonably well surfaced.
First time I went that way, a few years ago, it was being resurfaced. The Tarmac machine blocked the entire road!
When we rode it in June (on my CTC tour) the old drainage channels had been tarmacked over, but its still a very narrow, long, steep and tortuously twisty descent, with gravel on the bends, and various animals to avoid hitting on the way down. We normally take it very slowly on the way down, stopping to let the rims cool and taking loads of photos, so I still wouldnt want to see racing going on down THAT descent...With spectators in the way as well? Perhaps they will be CLIMBING the Saurenne, descending the Alpe, and later in the day , climbing the Alpe to the traditional finish at the top??
