I've been an avid cyclist my entire life, but have no interest in racing--maybe because I'm not particularly fast, though I'm a good climber. I saw the Tour de France once by accident while I was bike touring in France. For a couple of hours preceding the peleton, there was one advertising vehicle after another with a loudspeaker blaring. It was pretty unpleasant.
Having said that, I've biked up many of the famous climbs of the Tour with panniers, including the Col du Tourmalet in the Pyrenees, Mont Ventoux, and Alpe d'Huez. The latter was the last big climb I did in France, and it was a bucket list item for my friend who I was touring with. Alpe d'Huez nearly killed me, figuratively speaking. The grade varied much more than the others, and one of the steepest sections was at the very beginning, and I think that discouraged me a lot. It also was an unseasonably hot day.
When I biked up Mont Ventoux on a beautiful Saturday, there were hundreds of cyclists riding up the mountain, mostly on rented racing bikes from one of the outfitters in the area. I was riding my touring bike with full panniers, the only cyclist with panniers I saw climbing up the mountain that day. I took the easiest of the 3 approaches, and only the final 6 km were difficult. Few of the racing types who were passing me in those final 6 km deemed me worthy of conversation. One French cyclist was impressed by the fact that I was doing the climb with panniers and he actually slowed down a bit to speak with me. When he found out I was American (this was shortly after the Lance Armstrong scandal broke), he asked me jokingly if I was taking performance-enhancing drugs.
I'm another one who can't stand Phil Liggett. He always seems to sound excessively excited to me, even when nothing particularly interesting is happening.
