I used cyclemeter, when I was out, but I plotted the rides on mapmyride manually to see what the reading were.
REF the drop on the D1 into Sault, that first house on the right there, about 1/2 a mile before the Monnieux turning is the GITE we had .. lovely grounds and quite good fun watching the diferent tyes setting off UP that climb sometimes ...so that is where most of my routes start ...
For the gorge-ous ride you'd be starting by going up the gorge from VsA entirely on the D942 ..
if it looks like we went off track on that, (or anywhere else) then it is a trick of the technology cos it was all the road, which is in good enough nick.
Once you drop down from the Gorge towards Monnieux you are looking for the right turn (signed Methamis I think)
That's the D96 (or you can go further along, nearly into Sault and cross the bridge to take D943 for a bit of a shallower and prettier climb back up, then you need to cut back across on a little bit of road to the D5.quite near Saint Hubert -
from whence lovely views across the top of the Gorge, can out to Ventoux etc .. from then on it is all downhil, the most lush descent to Methamis and then VsA ..about ten miles of downward!
If you've never been up that little hill to Blauvac, on the left there before you get back to VsA, you might like the pull up as there is a restuarant with a great look out at the top (closed Mondays though!)
I love this ride cos that descent section is so remote, feels very different .. and yes, it was all actual road, albeit a bit broken in places, we were on good road bikes, and plenty of other roadies on it .. and scarcely any cars at all.
Think it clocks up a total of about 35 miles.
