OK. I found this site (most likely already knew about this site) and entered in the quickie route to my grocery store (just over a mile round trip) and found an oddity with the website.



It shows a nifty graph of the grade, but when I click out and back, the grades all change quite drastically. Now if I'm right, the grade of a hill does not change... it's pretty simple math of elevation gain over distance.

WHY does clicking out and back and thereby doubling the overall distance, make a 9% grade now 4-5%?

Does this look like a 9% hill or a 5%? It goes perhaps a quarter mile and does seem pretty steep, but I question 9%, so I'm wondering what ya'll thought.
