Default Climbing Trivia

The question came up on a ride the other day: can one climb stairs on foot faster than on a
road bike?

The answer I found, after some googling, is that the winner is too close to call. The fastest time
to climb the Empire State Building to the 86th floor is just under 10 minutes, which is a climb rate
of 100 feet/minute.

Pantani's record climb of Mt. Ventoux was done in about 25 minutes, giving a climb rate of 95
feet/minute. Pretty close. Ventoux is windy and has a variable grade. A road with less wind and a
more consistent grade should produce an even higher climb rate.

A couple of other things that don't make for a straightforward comparison. The added weight of the
bike and the difference in the length of the events, 10min versus 25min. However, my money is on the
bicycle being faster. There are some steepish hills I can go up at 10mph on the bike yet I can now
barely run that pace on the flat never mind up hill. Probably the runner improves relatively as the
grade gets steeper.

But what if Pantani only had to climb for 10 minutes at maximum effort? On the other hand could he
ride his bike up a hill with the same grade as the stairs in the Empire State Building?

Does this have to do with the fact that someone can fail to make it up a hill and still get off the
bike and push it the rest of the way to the top? Richard

I find it difficult to get enough traction on stairs with my road bike.

He undoubtedly could go faster over 10 minutes than over 25. Not a whole lot faster, I suspect.

Tricky, certainly, since stairs are very steep. I've noticed, however, that my climbing rate (in
vertical feet/minute) is pretty constant on grades between 7% and 15%. Steeper grades probably
wouldn't change the result much.

> Does this have to do with the fact that someone can fail to make it up a hill and still get off

Um, I don't think so. Walking a bike up a hill can be done very slowly, 1 mph or even less. Trying
to ride that slowly would result in tipping over. Walking is a last ditch way to reduce the climbing
rate to a manageable level.

Up in New Hampshire, they have a hill climb event up Mt. Washington.

The first time this race was run, it was won by local hero John Allis, but his time was slower than
the record for a runner on the same course!

He was using a regular steel racing bike, with his normal gearing. Subsequently, folks have been
setting bikes up more specifically for this event, and the pedestrians are no longer in the running.

I this this is the case of a strong runner passing a less strong cyclist. On steep grades (and thus
low speeds), an equally fit runner and cyclist should be close. After all, excluding the weight of
the bike (which is pretty small as a percentage of the total mass), the runner and cyclist are doing
the same amount of work to get up the hill.

The strategy is to continue to climb at the same rate, regardless of the grade. As long as you don't
tip over, and you have low enough gearing, 15% can be climbed at the same rate as a 7% grade. Say
you can go a fast-but-still-aerobic 10 mph on a 7% grade (~60 ft/min). To climb at the same rate on
a 15% grade, you must ride at 4.7 mph, well above the "tip over" speed.

20% at the same climbing rate (60 ft/min) is only ~3.4 mph, which is getting pretty close to the
"tip over" speed. There are a few 20% hills locally, and I find the best strategy is to take them
slowly. Or just sprint up them if they're short enough (100 yards or less).

But you're right: climbing the equivalent grade of a stairway on a normal bike would be impossible.
It might be possible, if a special bike were designed that fixed the low speed stability problem
(and it had very low gears).

But it is generally 10% or more which is a pretty significant amount in a race between individuals
who are at all evenly matched.

, the runner and cyclist are doing the same amount of work to
> get up the hill.

Another factor is the gearing available. Usually this is an advantage for a cyclist compared to a
runner at higher speeds where the cyclist can keep his cadence at an efficient rate by using higher
gears. But at slow speeds the cyclist on a bike without special gearing may not have low enough
gears to maintain an efficient cadence while the runner can shorten his stride as needed. David was
probably already in his lowest gear when passed by the runners.

7.6 miles, 12% grade. Based on the climbing rate of the best of the best cyclists, I'm going to
guess the best overall time is right around 50 minutes. Am I close?

Dear Terry,

The posts on this have been quite interesting.

Whichever way it works out, however, I cheer myself up by remembering that we win hands-down on the
descent without even pedalling.

I knew I kept those training wheels for some reason Now if Sheldon will just lend me his 63 speed
with 17 tooth granny fitted that should be just about right the right gearing for 3.4mph

Phil:

I think the fact that there is the extra weight of the bike is implicit in the question "Can one
climb stairs on foot faster than on a road bike?" Therefore that weight doesn't matter. You could
say that the race up the Empire State Building actually affects the runner's speed. It's not a
straight run; every 50feet or so the runner needs to make a right angle turn. I think what does
matter is the grade. Think about it. Can you run as fast as a bike on a flat road? No. Can you ride
a bike up a 90" wall? No. Yet a person can climb a 90degree wall. Somewhere between those two angles
is the crossover point. Stairs are usually closer to a 35 degree angle which is still pretty close
to unrideable. At that angle I tend to believe that balance comes into play more than anything else.
A person can get a gear ratio to support the angle but can they ride a straight line for a long
period at close to 1mph. I would expect the crossover point to be somewhere around a grade of 15-18%
for the average person, and I'd expect it's a little higher if you were to compare an elite cyclist
to an elite runner.

MOO, of course! Matt
