# Vertical feet VS Mileage Skied

Bears,

Spent two days recently at Keystone where we totalled about 69,000 vertical feet- maybe not a big deal to many of you but the most I ever skied in 2 days. I was wondering if there was some kind of "rule of thumb" calculation I could use to convert the vertical to actual miles skied. I know it depends on the grade of the slope but is there an average grade for a typical blue groomer- that is what we skied primarily. Comments/thoughs would be appreciated.

Measure the smile on your face, multiply that by the verticle feet, add memories, that is how you get the mileage out of your trip.

Smile x Verticle Feet + Memories = Mileage
I'd guess that a typical blue has a slope of about 1:2 or to 1:3... so multiply vertical feet by 2 or 3 to get linear distance skied.

Unless you turn!!

A typical blue probably is something like 20 - 30% grade, top to bottom. At its steepest it might get up to 50%.

Say 25%. So you'd travel four feet horizontally for every foot of vertical ... actually you'd travel slightly farther, because you are travelling vertically also. The hypotenuse (total distance) would be sqrt(17) = 4.12 feet for every foot of vertical.

20%: sqrt(26) = 5.10
33.3%: sqrt(10) = 3.16
50%: sqrt(5) = 2.24

If you turn, you're just wasting energy.
