I rode up Morrison Canyon Road for the first time today. It's only about 9 miles from my home so I had a nice warmup.
Good thing because that sucker is freakin' steep! It's about 2 miles or so of climbing but I could only manage ~ 1.5 miles before bailing out. What I did manage averaged out to a 9% grade with some sections kicking up well over 12%. booyah.
The descent was pretty dicey. While I'm a good descender for the most part, I took this one very cautiously, since the road is only a single lane for the most part without good sightlines. I hate it when I'm not rewarded for my efforts with a fun descent! 
I wore my HRM today and my hr went up to 187 (which was interesting since I thought my max HR was 185).
But apart from the eye-popping climb and the dicey descent, it was a nice ride and I felt really good. Good start for my 50th year.
