Ride the steepest hill in your town

Trek Emonda lightest production road bicycle

I’m endeavoring to Ride Every Road in my small town and log the rides to Strava. Some of you asked why I would do that. Mostly because it’s a reasonable goal for me, but a side benefit is finding a road like Grace Way in Scotts Valley.


Near the bottom of the steep part.  Grace Way, 95066

This doesn’t look like much, but my phone inclinometer app says this hill is 21°. That’s a 38% grade, boys and girls.


21° = 38% Grade.  Grace Way, 95066

The infamous Baldwin Street in Dunedin, New Zealand tops out at 35%, while Canton Avenue in Pittsburgh officially measures 37% for a short stretch. Filbert and 22nd Streets in San Francisco are 31%.

My friend Chris biked over from Santa Clara County to my side of the Santa Cruz Mountains specifically to challenge Grace Way. He shot video as he approached this road using his Garmin Virb Elite. Watch the gradient shoot up beginning at about 1:50 in this video. He was forced to stop when his chain skipped while in the big cog.



What’s the steepest hill in your town? How did you find it? Would Trek’s new $16,000 bike weighing 10¼ lbs help you climb it faster?

    do you have a good google maps link for Grace Way? because the only one I find on google maps sure doesn’t look like this one:

    Keep going southwest from that point to where Streetview runs out, and keep going from that point.

    21° are no way 38%.

    Please explain, @diklin? The arithmetic and my assumptions are basic, but it’s possible I got both wrong. Gradient is just rise over run, so 45° = 100% grade; half of that = 50% grade or 22.5°; and of course 0° = 0% grade. Interpolating, we get a bit over 38% grade for 21°. What did I miss?

    Richard, you’re correct. @diklin might be thinking of gradians and not gradient (grade). There are 360° in a circle, and 400 gradians, so 21° is ~23 grad. Gradient is slope.
