Turns out the alternate route (Cote de Domancy) from yesterday didn't attract too much attention. I rode it once at 100% and once at 50%. I was a bit surprised I got the polka dot jersey at 50% elevation. I was the slowest ever rider, but there were only 23 people that have done it at 50% when I rode it. Apparently nobody else was doing it when I rode it at 50%
I wish I had thought to take a screen shot one of the times I won the green jersey, that was a bit more of an achievement

I finally realized what the logo on other rider's butt signifies, it indicates the % elevation they are riding.
