From what I read on the 14ers forum, it's very unlikely that they finished TH-TH in time; They needed to cover the summit-TH in an hour and those who'd traversed it said it would be "flying" down the mountain, which seems extremely dangerous on such exhausted legs.
It seems to be well agreed upon that they wouldn't had no issues doing it but they celebrated for 2 hours at the last summit instead of continuing down to the cabin (probably a much more inspiring place to party with their crew than at the cabin)…I'm guessing they felt they accomplished what they set out to do and had no intentions of appeasing others.
Interestingly enough, the list of those who are saying they didn't finish in time to be "Nolan 14 finishers" includes most of the people who's went TH-TH in under 60 hours as well as the unsupported FKT holder, who finished TH-TH in 60:19 and called it an "epic failure" since he feels he did not complete it in time.
I'm now where near capable of even doing half of the Nolans 14 in 60 hours so my opinions should be taken with a grain of salt…but after reading the history of how this challenge has evolved over the years (times, prep, and how popularity is growing fast now) it makes me wonder how tangible an unsupported TH-TH finish is for people.
To me, unsupported times should be measuring stick for finishing. The fact that nobody has accomplished it in 15 years seems to say a lot in terms of how exclusive the group of finishers will be in the next 5-10 years
Supported attempts are still incredible but I find it ridiculous that over the past 15 years to even qualify as a finisher an attempt MUST include support crew.
