I did this on my 990R a couple years ago but took the Lamartine road instead of Cascade Creek. Basically start at the same point near Idaho Springs. It was not nearly this rough! And you didn't film the best part - coming down the switchbacks into Georgetown.
@ZJBuilder i did film it and I will upload it this weekend By the way it was rough and I broke my bike chain at red cone so I was little scared of that if it happened again
