How fast (or slow) did the Tour riders go UP the mountains?Fez

Did they keep it in double digits? I do climbs far less steep than those in the Tour and I drop down to 9 mph regularly!
15-17 mph?DougSloan

Judging from reports from Phil and the riders' power outputs, it looks like they easily keep it in double digits, with the faster ones around 17 mph up 8% grades. Incredible.

have you ever noticed sometimes the people running alongside can easily keep up with them? I am sure they often get up to 17mph. However, I don't think many people could run uphill this fast. Thus, I would have to believe they spend some time in the lower double digits climbing.
Also, I would hazard a guess that the guys Lance is dropping do indeed get into the single digits occasionally.
sounds about right nmDougSloan

on Alpe d'Huez a few years back he averaged 13mph or so. That's a bit steeper than a lot of climbs though, so 15ish is probably about right. Jeez, there are hilly rides I barely average that on for the whole ride!

Alpe d'Hues is only 7.9% avgcyclopathic

but I think they went up the Galibier that day so it is absolutely stunning
We worked out the climb rate once ...Humma Hah

... in a TDF discussion a couple of years ago. I believe someone had data on Elephantino, and he climbs about 120 feet per minute, and Lance would be just slightly faster. Once you're in a serious sustined climb where wind speed is not dominating, rate of climb is probably a better indicator than road speed, because the grade is changing so much.

I belive we decided Doug Sloan was capable of about 80 at that point in his training, and I was typically hitting around 40 fpm on a good day.

Okay, so let's figure what, about an 8% slope. So he's moving 100 feet forward for every 8 feet he climbs. So, that's about 1000 horizontal feet per minute. As it's 100 * 80 / 8. Right???
Now, let's go back to good old Pythagorous who says AA + BB = CC.
C is unknown, A is 80, B is 1000. This still sounding reasonable?
So, 6400 + 1,000,000 = CC.
1,006,400 = CC
So, that's just over 1003 feet per minute, which is about 1/5 of a mile per minute. 60 / 5 = 12.
So, that's about 12 mph.
That was a fun little math exercise.
