Including travel to and from Le Havre, I only had 5 days, so it was done at a fair pace. Left each morning by 9.30am, stopped at the top of every pass for a break and to admire the views, stopped for petrol where necessary and stopped for 30-60 mins for lunch. We rode each day until about 7pm. I would have liked another 1 day so that I could have gone all the way down to Menton. On the last day we rode up through the Parc Vercors and came out at Grenoble. From there it was a blast for 200 miles up the A6, stopping for the night at a Formule 1 on one of the service stations 110 or so miles north of Lyon. On day 5, we left the motel about 8.30 am and got into Le Havre mid afternoon.
I'll try and finish the rest of my trip report off which i think completes the last day or two.
Last yr I did "around" Mont Blanc and the Andermatt area, but enjoyed this trip more - the scenery was better and the roads were superb. napoleon route was busy and a little unsettling at times given the speed of some cars, though I didn't complete all of that.
