Excellent route, on a perfect day. Heeding the great advice of my predecessors, I filled up at Notch Lake. That was my only fill up, but I am notorious for not drinking a proper amount of water. It was also a nice cool day. Rick also had a great heads up about the "not at all obvious" turn shortly after Notch... I just wish I would have remembered it. I also intially missed the turnoff for the climb up Diamond to the summit, but fortunately neither was tooo significant of a backtrack. Those junctions are worthy of keeping an eye out for if you're moving and don't have the map loaded on your watch.
Like Tori said, this is *mostly* runnable & super fun! But also, those hills can get ya in the back half. Looking forward to seeing this FKT board continue to grow.
