What Does 25% Grade Look Like?

[Eden]

Eden, let's go out with a bike computer and an altimeter; we can figure it out!

It would be easy with that info - rise over run! shucks tho - I don't have any fancy gadgets like that - spent all my money on the fancy bike....

oh.. I don't either! But Raleighdon has enough of that equipment to drive his bike out into space.

US geological survey topo maps will let you get an approximate grade for large hills. I've cross checked them on hills I know have a posted grade, and it's usually pretty close (+/- 1% or better). The only depressing part about checking them was discovering that my nemesis hill is a piddling 5% grade on the steepest incline. *shakes her fist at Wisconsin for being so flat*

Torrilin, Torrilin, Torrilin...what am I going to do to convince you that not all of Wisconsin is flat!?!?!?!?!? Where are you located? Perhaps I can help you find a real hill?

Even with the fancy gadgets, getting a good measure on a hill is hard. A good lock on my GPS and all measurements are still +/- 15m. I've gotten pretty good at doing running averages when I'm going up hills, ignoring those first glimpses of 10-12% unless I see a lot in that range. I have a hill that I can see several spikes into th high teens, but it averages out to only 12%.

In Italy we saw some really steep grades...going into one of the hill towns was a 25% grade. Quite a bit longer than your road, Mr. Silver, but I will admit I didn't make it up the hill...oh, it wasn't that I ran out of oomph...oh, no...it was because I was moving so slowly the horse parade caught up and I had to pull off, of course Seriously, there was a horse parade, but, ok, I really wasn't going any farther. 25% is really steep--I'm impressed you can get up that hill.

Oh, and I agree with Eden--all inclines start to look the same. I have some 4% grades nearby that look almost flat, but in Italy, after climbing for an hour, I was convinced the road was going downhill, but I looked at the GPS and it said a steady 4%. It is just a matter of perspective.

I'm in Madison. And I know it's not *all* flat, but I'm used to the mountains around LA and central PA hills. So lots of things that a sane person would say is hilly I look at and go "that's flat".

Never claimed to be sane tho

Sure...we ain't got mountains, but I guess I prefer rollers for training--consider it speedwork for those long mountain rides you really want to do when you go back to visit LA and PA!

If you're in Madison, you're just a hop, skip, and a car transport to Bluemounds. The Horrible Hilly people keep their cue sheet on line--http://www.horriblyhilly.com/course.html Never long by mountain standards, but many steep hils. That route was actually plotted to maximize incline. A little west still has some steep ones... Try http://www.dairylanddare.com/ for another cue sheet.

Of course, I'm rather smitten with that area of the state--rolling hills, gorgeous land, relatively friendly vehicles. Sigh..but I'm a long way away.

But count your blessings--you could be located in the Stevens Point area--the sandy flat lands of the former glacial Lake Wisconsion. I think Florida has more hills than they do.
