So I did Alpe d'Huez a few days ago for the mountain goats league. I didn't note my exact time when I was done, but it was on the order of 55 minutes. I thought not bad at all, far better than I expected. But when I went to the website later, it had me at 1:23!?!
Figured that was awful strange, so I did it again this afternoon and noted 52:22 as my finish time. Head to the website and it's got me at 1:19 (main part, ignoring warm-up/cool-down).
So that's a big WTF. The 1:23 and 1:19 make more sense if I look at my average speed -- while there were stretches above 7.5mph, I certainly didn't keep my speed up that high for the duration of the ride. So there's no plausible way I could have actually done that ride in 52:22.
No clue what's going on, but it's awful annoying.
