My childhood hill...19.9% Grade

[Mr. Bloom]

How ironic, Birmingham is the Pittsburgh of the South. But all the steel mills were on the relatively flat west side of town.

I used mapmyride to quench my initial curiousity. Silver and I said that we would try to ride it next time we pass through on the way to the beach!

How did you calculate the grade? Did the mapping site do it? I'm impressed if you did it! I used the Pythagorean Theorem and got 20.06%. If you had made a mistake and used the .13 miles as the horizontal distance instead of the hypotenuse, you would have been off a bit and calculated it at around 19.66%. I can't wait for someone in my geometry class to say "yeah, and who else will ever use this besides you?" I'll say "Why Mr. Silver used it in November!"

By the way, that's an impressive hill!

[Mr. Bloom]

Honestly, I relied on the mapmyride distance and I don't know if that was horizontal or not...but it's a short distance. I also relied on their ascent calculation. Personally I would have guessed it was higher...

My calculation was 135 feet of ascent divided by .13 mile.

After a horzontal run, the final climb is about a 40 foot climb over 100 feet. This is one of those hills that you couldn't see over as you crested it in a car (and in 1972, our friends car couldn't crest it without a running start and all the kids leaning forward)
