On August 13, 2014 at Snoqualmie, we ran into Ross headed south on what he called the first ever PCT unsupported hike on the PCT through Washington. His definition of unsupported also included no resupplies, which I guess means he left the Canadian border with 500 miles of food.
If my memory is correct, he mentioned pulling 40+mpd, except in some heavy blowdown areas where his mpd dropped into the 30s.
The night before it rained the entire night - a huge storm; we had thunder/lightning from 5:30 pm until midnight or later. He said his shelter was his weakest link in regards to his gear and thus opted to spend the night in the Snoqualmie trailhead privy, which he described as so small and filthy that it was OK per his "rules" of unsupported.
I've not been able to find anything about his hike on my google searches.
Anyone have an update? Could be an interesting read.
