There's a road nearby I'm not strong enough to get up. I'm looking at it in google maps, and it's ~4.5 miles and ~2500 feet of elevation gain. ~1500 ft is in the first 4.2 miles. Leaving ~1000 feet in ~.3 miles.

That's, uh, unreasonably steep. Like, 63% grade steep, according to bicycle e-tools: percent grade, average speed calculator, gear-inch chart

I have my doubts about the accuracy for that last bit. So-what is the best website to get a better measurement? Since I can only make it up about halfway, and the descent is terrifying, so checking it out for myself isn't on the table for a couple months.
