How tall would this mountain be?

Parameters:

You start at sea level. 0 feet elevation, I know the answer, do you?

I hope you were wearing Ti Heat shield and were on a Ti bike! That descent must have been.......meteoric!

As much as I enjoy climbing, I think I'll pass on this climb. I think I'll pass on the descent, too. I've done 56 MPH, and I think 70 MPH on a bike is about the max I'll ever allow myself to do.

You mean you don't want to go down a hill so fast you leave an incandescent plasma trail behind you? You're no fun!

No thanks. I'd like to survive the trip.

Back to reality...The fastest I`ve done is 63mph...I had help because a van passed me while I was at 45mph and I cranked it up and drafted him to build speed. He pulled away and I maintained 60mph for maybe 15-30 seconds but I could not spin my cranks any faster. Gearing was 54/11. I didn`t feel out of control but I also ride motorcycles so maybe I was used to it already. It was fun

I believe it's in that neighborhood, yes. I'm not actually sure though! I had just created a joke sign and figured out how tall that hill would be, and next thing I knew, I was posting this thread!

You would probably wear out the tires on the ride down. Watch out for that bump...talk about road rash!

I just realized something, your avatar looks a bit like what you'd look like when the aerodynamic pressure exceeded your ability to hang on to the bike on the way down!

If the bike had some off-road descents, it would definitely require "the most advanced, toughest wheelsets" imaginable.

I got a different answer, 22.144125 miles

The 125 miles is the hypotenuse as the sign indicates that the road is 125 miles long, it is not the adjacent (run, used to calculate the slope).

A slope of 18 % = 10.203974° (ATAN(.18))

The opposite (the rise) is 22.144125 miles (sin(10.203974) * 125)

Who friggin' cares; this is a bike forum, however loosely related Foo might be?? It's WAY to tall for me (or any of you... even at 401 watts!) to ride up! So for our purposes, what difference does it make if it's 22.14415, 22.4, 23, 121K KM or 4x any other mountain??

Practicality... too many brain cells to waste on this one!

Hmmm, I figured linear distance on a constant slope of 18ft rise/100 foot run and multiplied it out.

That is the problem, the slope is rise/run (opposite/adjacent) but the road sign indicates the hypotenuse. (the distance that would be travelled by the vehicle). Normally for bicycling hills, the difference is so minute that it doesn't make much difference. But for a 125 mile hill at 18%, the difference between the hypotenuse and adjacent starts to become significant.
