In my opinion as long as it was "random assistance" or whatever, the hitch does not disqualify this FKT, but, it clearly does not meet the same standard set for herself by Annish or himself by Kirk, etc. Oh, Annish was so pure! Kirk too, but I didn't watch his hike in real-time so I'm fonder of Annish.
If it were me, and it might be someday (I'm thinking of attempting to "shoot my age" on the the AT, that is hiking the trail in the same number of days as years I've been alive -- 60? 70? I'm 43 now so still time to train!) -- I would avoid hitching or cars of any sort and would try to plan my resupplies right on the trail or as close as possible. Duh! Annish and Kirk did well with this, wasting very little time/miles.
This raises an interesting idea that perhaps that way to appreciate and evaluate these FKTs is to consider them as demonstrations of technique and skill and stamina, rather than as races against existing time. Perhaps we should consider their purity, efficiency, grace, power, etc. Sort of like we would evaluate dance, music, martial arts, etc... Just a thought.
As for the 12 mile round trip into town -- that looks like a desperation move to me. Surely she didn't plan for a supply drop 6 miles off trail. But who knows with this one! I know her feet are hurting like hell and if she's favoring one or the other then the pain is moving up her legs into her knees and hips and back. At least that's been my experience. A pinkie toe blister turns into locked-up hip... Knee bone connected to the thigh bone...
