I've been an avid ultra runner for over 10 years now. I've one multiple 50k ultras and have podiums in other ultras as well. I just won the US sly runner championship race last year shortly after I got the Harts to Rainy FKT. It really is an iconic point-point run on the PCT and is definitely considered one of the most beautiful sections on the entire trail. I've ran it a couple times and on my third attempt went for the FKT.
