Riding uphill is sometimes more psychological than physical.

and sometimes percentages don't convey what you are confronted with. so another way to look at this is this way. You will be riding a trail that gains 1700 feet. But it does so over a distance of 132,000 feet. IOW, your local MUP probably has a steeper grade.

OTOH, sometimes not understanding how grades are calculated can lead to trouble. Like looking at a map without a grade profile and reading about the 6% grade over 10 miles and thinking, "6% is pretty low that shouldn't be a problem" Then when standing at the bottom and looking at what seems to be straight up you are swearing that's a lot more than 6%. But it's not.
