question about climbing

I live in the flatlands and not a great climber but pretty solid rider. I have done some climbs according to various categories that are 3 and 4 rated. I got them ok on a 34-28 but not just easy. So I see the Alpe D'Huez and the rating plus going up 8 % for over 8 miles seems a bit much for me to comprehend.

Do most mortals who do the Alpe D"Huez go up without stopping during the climb? One climb I do is overall about 6% and it goes on for 1.2 miles. The very last section gets to 9% or about maybe 1/4 mile. I tell you I can get up no problem but I just cannot see keep that up for another 7 miles. I am pretty spent the last 200 feet.

So I assume those climbing these on tours and such are pretty decent cyclist but what gearing. Would a 34-32 really make it that much easier to manage than say a 34-28 that I use now. They say sitting is the best way to climb but I guess I just do not do enough of it to really tell. I do know that when I am around more hilly terrain after a few days I get better at climbing.

Does the average cyclist planning to climb something like the Alpe D Huez factor in a break of a few minutes at some point or points. Any climbing experts in this group.
