I've just been looking at the parcours - I run a series of cycling challenges on a health and fitness website, that are themed around the 3 Grand Tours, and one of the things I need to have recorded for the challenge is the ascent logged (i've looked all over the place, and the only way I can get it is actually to stick the route from the "race bible" into mapping software and let the software crunch out ascent figures.) - so I get a bit of an insight into the route and the gradients involved. I'm only at stage 10 in the mapping, and already theres more climbing than the first 13 stages of LeTour... so, it's looking like it's going to be a tough one...
But, to answer you're question, yes - i'll be SKY+ ing the Eurosport coverage, so that I can get out and ride myself through the day for 2-3 hours, and then I can watch the race when I return (fast forwarding through the interminable advert breaks)
