Not scary at all. Just 6.5 miles of sustained climbing, average grade of 4 - 5% with pitches to 9% in the section I did today.

The upper half, which is closed right now, is harder. It's 4 miles with an average grade of 6%. Then a quarter mile of 17%.

But I ride it a lot. It is a good benchmark to see where I am. It's also the reason I have a tiny front chainring.
