I've switched to a longer bike ride in the mornings, which takes me up a steep hill about a mile from my house. The hill's only 74 feet tall, according to strava, but at an 8% grade. One of the segments covering it is called the 'Williamsburg Soulcrusher'; slightly over the top, I'll admit, but I'd call it the Legcrusher without a second thought.
It's made a bit worse by having a quarter-mile or so of slight incline leading up to it, where you can see it coming. Ugh.
Anyway, it gives me a lot more appreciation for the Tour de France riders, who regularly face inclines that steep that are far, far longer than that. I certainly don't envy them those climbs.
