I've ridden portions of that route and up Hurricane Ridge Rd. several times, as well as taking the ferry from Port Townsend to Whidbey Island and riding around there some on regular non-assist bikes. Not since the trail along Lake Crescent has been finished though. I was going to ride it this summer/fall but I was told Moro campground doesn't follow "no turn away" for bikers and a small motel in Forks that used to be less than $100/night was over $200/night when I checked. I'm not sure about camping on the beach.
I started watching that video, I'll try again later with the sound off, she was super irritating to listen to.
