Today I finally rode... er rode most of, the Los Gatos route. Steep doesn't begin to describe the hill on Los Gatos. My Garmin registered greater than 25% grade! It was so steep I was really struggling with keeping the front tire on the ground while standing and putting everything I had into it.
It kicked my butt, I wound up walking a short distance.
Here is a profile...
I hope to go back and try again, maybe I will try it on my mountain bike. Yes it is that steep!
