Yep, I've done it before.

What I remember most was getting to the "top" and looking at the accumulated elevation gain & realizing that A) The way out of the finish area was a lot of up, & B) the number indicated on the display wasn't nearly all the elevation to be had that day.

I then carried my bike up the steps to the observation area just for good measure.

The last 20 miles were the best. There was a stiff tailwind & for the first time I wasn't rolling on rough broken roads haphazardly repaved with aging chipseal. About halfway down the return, I dropped my tire pressure to about 80psi. Kind of low for a clyde on clinchers, but necessary at the time.

I outfitted my bike with an 11-32 cassette. I'm glad I did.

Great views. I would definitely do it again.
