Jim,

After all the work you did for me to demo you skis, I hate to be the person that bursts your bubble, but......your math is incorrect.

100 x 100 = 10000
? 25 x? 25? =? ? 625
Total? ? ? ? =? 10625

Sq. root of 10625 = 103.0

So your 115,000 vertical feet yields only 118,000 ski trail feet or 22 miles

Just go skiing with Lynn and enjoy the view(s).

Uh-oh, now this is getting sad.? ?;D ;D

Mike, what is the calculation that gives you 118,00 ski trail feet from your numbers?

As you said, for every 25 feet of vertical, I get 103 feet of ski trail feet (not my 225)?
However,? 115,000 / 25 * 103 = 473,800 ski trail feet, and 90 ski trail miles.

And, Todd, that means I only lost 54% of my length. (whew? 8) )

By the way, if I'm wrong again in my math, I plan to ban myself from the forum.? ?;D
And I can't wait for Lynn to read this, I can see her rolling her eyes already.
And laughing hysterically at guys in general.


Jim,
Two wrongs and we finally got it right.

I looked at Blue Mountains website. Their 6 pack chair rises 1050 feet and the chair length is 4300 feet, so very roughly it conforms to your 4 to 1 length to height (100 to 25) model. An approximation is that one run is 5200 feet of skiing or about 1 mile. (Some are shorter or longer). So skiing 20 miles per 4 hours is reasonable based on 5 runs per hour.

Now, damnit, go skiing with Lynn and enjoy the views.  ;D And do the drills ::)

In my younger days of skiing, I worried about how much vertical I did skiing. My skiing mentor always told me to worry much more about how much horizontal I got at night. But that was a long time ago.
