That's quite possible. Peronally, I am not
frightened by steep, difficult climbs. I am
much more frightened by long flat stretches.

Come to think of it, you can find a road like that
at almost every single ski area in Colorado.

Imogene Pass, on the Telluride side, sustains
18-20% for its final 3k stretch to the summit
at, get this, 13,114 feet above sea level.
When you're climbing grades like that over
12,000 feet, it's a whole different ballgame.
Europe can't match that. Mosquito, Argentine,
and many other passes in Colorado are similar.
Imogene I think is the toughest I have ridden
so far.

(The mileage cues on this jpeg are from a foot race
held each year over Imogene, from Ouray to
Telluride. I've only ridden the Telluride side. Notice
the brutality comes on the left side of the map,
climbing into and out of the aptly named Savage
Basin from the old Tomboy camp, which was
repeatedly swept off the mountain by avalanches
while it was inhabited in the late 19th and early
20th Century.)

Here's a fuzzy picture of the pass from the
Telluride ski mountain. You can't really see the hard
part of the climb in this picture, though:

http://www.imogenerun.com/images/ricspics/r01.jpg

If anybody's planning on coming out from California
to try these passes, I'd suggest starting with
some of the more tame options, like Engineer,
Cinnamon, or even the low and smooth Weston,
just to see if you can deal with the pronounced lack
of air pressure before losing your lunch on our big
daddy climbs.

In this old interview, Johnathon Vaughters, a Colorado
climber who set an astounding record on Mont Ventoux,
gives his opinion of European versus Colorado climbs
in pro races:

"Any climb in Europe is a little bit more power-based,
even the long climbs; since you're down at a lower
altitude, you've got more oxygen, so the game is a little
more power-oriented. When you're doing races in Colorado,
you're up at a really high altitude to begin with, so it has
a little bit more to do with really pacing yourself and
adapting your body to get used to working in really thin air."

While the Euro climbs are steeper, Vaughters mentions
Guanella Pass as one with the rare combination of
high altitude and grade. In the Saturn Classic, a race
that Vaughters has not surprisingly won (140 miles,
14,000 feet of climbing), Guanella Pass is rated
hors categorie (HC) on the Euro-freak scale.

Dear Robert,

We'll probably just end up disagreeing about emphasis.

I've heard rumors that California and Europe have ski
resorts, too, not just Colorado.

And I'm not sure how to reconcile your "a whole different
ballgame" comments on altitude with "a little bit more" and
"a little more" and "a little bit more" from Vaughters on
the same subject.

I think that Colorado does have a few roads that may rival
the impressive climbs of Europe and California, but not
nearly as many as some of my fellow Coloradoans think.

Yes, we do add the handicap of higher altitude and its
thinner air, but then we also start about six thousand feet
higher, which means that our actual altitude change during a
single climb is often quite a bit less than seen in
California and Europe.

The point that strikes me about the "Euro-freak scale" that
you mention is that they have the kind of terrain and
interest that produces such a scale--and considerable envy.

There is a nasty corner, perhaps the last tight one on the way up (heading
west), where the downhill direction probably does hit 24% (possibly even
more) for a very short piece, maybe if measured over 30 feet or so.
Fortunately, you don't have to climb up anything like that, but on the way
down, it's, well... just plain silly. I clearly remember Bruno, my service
manager, actually laughing as he descended it. It just didn't make sense
that a road would do something like that, and he found it rather funny. It's
called Pacific Grade, by the way.

The long, straighter stretch leading into it is actually much tougher. I
doubt it gets up to more than 12% or so, but you feel it. By the time you
get to the nastier corner, you're able to see that the road levels off a bit
just beyond it, and provides the incentive to keep going.

There seems to be no good way of quantifying how hard a climb is. It depends
on how steep it is, long it is, weather, elevation, how tired you are, how
hard you push and how good of shape you are in. The Sonora Pass highway may
have a spot where the gradient is 26% but it must be very short - I would
say a few feet on the inside track of a hairpin turn. However, a few feet of
26% might be impossible for some riders or if it is icy. I have a bike
computer that collects barometric elevation data but that is problematic
also.

I think the most useful description of climb steepness would be to state the
average gradient over some distance - say a mile. Someday I should start a
thread "the steepest mile."

There is a 1km stretch of Sonora Pass that averages almost precisely 20%.
That's about as tough as I'd ever want to ride, especially at altitude. The
"toughness" of a climb is, as you mention, more than just how steep it is. I
would put Mont Ventoux up there as a climb nearly as tough as Sonora Pass,
even though it has *no* exceptionally-steep sections. It's just plain
relentless, with multi-kilometer sections over 9%.

As I recall there are 4 steep stretches on Sonora:

1) Leaving Kennedy headed east:
http://tinyurl.com/3n4up
About 14% for the steepest km

2) The "Golden Staircase", "Corkscrew" or "Queue de Porc." East bound before
the summit:
http://tinyurl.com/47fl6
About 14% for the steepest km

3) Arrival at the summit west bound:
http://tinyurl.com/5snwt
This looks like about 14% for the last km.

4) Leaving Leavitt Meadows west bound:
http://tinyurl.com/63zj7
About 18% for the steepest km

I plan to ride Sonora as training before the Death Ride this year and will
take the logging barometric altimeter bike computer and a gps logger so I
can map the route as best I can - anybody wanna go?

The hardest climb for me was Hicks Road/Mt. Umunhum Road out of San Jose.
There is a 5 mile stretch that climbs almost 3000 feet for an average of
10%. A relentless 5 miles. I rode this with a thin fit 30 year old when I
was a slightly out of shape slightly over weight 47 year old. I really
though I might spit up a lung - the kid made small talk the whole way while
giving me sad looks.
 
So what's the grade on Page Mill? I never climbed it, but I blew both tires,
simultaneously, descending it on the tandem.

Dear PB,

Here's a list of elevation gain and mileage for some
California climbs, with some sort of difficulty rating
thrown in:

http://www.actc.org/billygoats/bgoats.htm

It shows Page Mill at 8.4 miles and 2,210 feet of rise,
so 2210 / (8.4 * 5280 = 5% average grade.

I expect that there are much steeper sections.

Page Mill is rated 5 on a scale where a number of other
climbs are rated 6. Such difficulty ratings usually combine
both distance and grade--a 10 mile 10% climb is probably
rated as harder than a 1 mile 15% climb.

It would be nice to find a site listing California and
Colorado climbs with the kind of profiles found here:

http://home.sprintmail.com/~dsjansen/Mtn_Climbs.html
