This thread (and others like it) highlights the difficulty in recommending which way to go and how long anything will take.
In his post Greenman14 says:
Hi, 6 of us doing Santander, Pyrennees, Corsica, RDGA, Reims, Calais.
but then goes on to say:
Have currently allowed 2 days for Menton to Val d'Isere which seems possible but for sure not very relaxing. Prefer to limit riding to 6-7 hrs/day. Any advice?
The obvious answer is, then take longer if that is what you want to do. For instance, take three days not two, if that enables someone (unknown) to hit a 6-7 hours a day target. But that might not work if Greenman14 and his five chums has to be back in Calais on a certain day, meaning that he and they will have to make up the 'extra day' somewhere else. If they can, fine. If they can't then they'll have to take a view. There are six of them on what seems to be a reasonably long jaunt (maybe some time next year, we don't know) so we can assume that they will be able to work it out between them, as it's half the fun.
Similarly, 'riding for six to seven hours a day' is all but meaningless. Why?
(1) Is that moving forwards for 6 or seven hours, to which stoppage time is to be added? If so, and assuming two fuel stops (15 minutes each) a coffee and tea stop (30 minutes each) and lunch (one hour) that adds two and a half hours when you are not moving forward at all, bringing the day's total 'riding time' door-to-door to between eight and nine-and-a-half hours.
Add in perhaps two or three photograph and / or wild flower pressing stops of 15 minutes each and another 30 to 45 minutes are gone. If someone averages between 35 and 45 miles an hour they will have lost a combined total of about three-and-a-quarter hours, which is about 130 miles.
(2) What time does an intrepid traveller intend to start and stop the day?
I know bods who are happy to get cracking at 08:00 and keep going.
I know others - which emphasises point (1) - who struggle much before ten, want to stop at 11:15, stop again again for a two hour lunch at 12:30 and be in their hotel by 16:30. That is 'six and a half hours riding' on their clock. Not surprisingly the latter bunch do not get that far but they are very happy, which is fine.
(3) You get characters like Rasher who want to take longer but only because they want to ride every col and pass in a 50 mile radius of where they stand at any one moment, take pictures and create very good trip reports. On the same bit of road as Rasher you'll find other fellows who just want to go from A to B to C, riding the roads as fast as only they can, not stopping other than for a swift sandwich and fuel. And you'll find a whole bunch of riders somewhere in between and some more at the outer extremes of either end of the spectrum. In short, they will all tell you something different. They will all be right and / or all equally wrong.
So, Greenman14, work out what you and your companions want to do, based on your preferred riding model and not least your overall timetable. Then come back and tell us.
