Josh Garrett completed the PCT from south to north in 59d8h14m (June 10 - August 8, 2013). Garrett's trip was supported by people meeting him at road crossings, so that he was able to carry the minimum amount of gear and food (still a lot on the many long sections between roads). Garrett's trip was also a fundraiser for animal welfare. Many articles about Garrett's remarkable trip are available online. Here's one that discusses both Garrett's supported trip and Heather Anderson's self-supported PCT thru-hike FKT from ESPN Endurance Sports.
