This should be interesting. Ben has the FKT on the GA Loop which is "only" 58 miles and he did it in a little less than 11.5 hours. Long Trail is what, 273ish miles? FKT is roughly 4.5 days.
He is doing this as a supported attempt.
Progress so far reported:
7/10: Started 5:00am
7/11: 57 miles after 24 hours
7/12: 110.2 miles after 48 hours (took a sleep hreak)
7/13: 169 miles in 72 hours
