Thats not a FKT, thats a half day race.
You even ran uphill?
Most people walk uphill, run downhill. Except the very elite.
But they arent running a course like much of the AT either. Its one thing to do it for one day, its another to do it 50 days in a row.
Personally, Ive always felt like if you had to jog slow, stop, walk ,rest, take a nap, be evaluated by medical, have your feet repaired, it wasnt really "running". It is ultra something however. Ultra endurance, yes.
I dont think Im running unless moving over 5mph. My brother thinks the same about 6mph.
