    I did this in 15 hours, 2 years ago. I'm checked in at every box on the trail but I didn't have an all trails map or any tracker at the time. Moving onto NEU8

    According to quite a few older blog posts on CascadeClimbers, Miles Smart did the West Ridge car to car in 5hr 45min in the early 2000’s. That’s the fastest time I have come across online but wouldn’t be surprised if it has gone faster since then.

    SOBO attempt from the NY/PA border on September 11, 2023.  Hit 50 miles in 13 hours and was well on my way of reaching my goal of going sub 30 hours.  Got stomach distress at mile 60 that I was unable to overcome and decided to DNF at mile 80.
