Determining hill grades?(3 posts)

Determining hill grades?chrisD
May 8, 2001 11:21 AM
i've been using joe friel's training program this year and have found it pretty useful...

i have one question though...

every so often he reffers to the grade of a hill expressed in a percentage (ex. "a hill with a 4% to 6% grade").

how can i determine the grade of a hill without knowing how long or high the climb is?

You'll need an inclinometer. The Western Wheelers used to have a web page with info on how to make an inexpensive one or you could buy one. All you really need is a plumb bob and a sheet with the anlges/% grade figured out on it.

You can also use mapping software from companies like DeLorme (www.delorme.com) to calculate grades.
