I read this too and thought the route would be interesting, but I'd need at least a month to do it. I am fascinated by the endurance cycling e.g. the Transcontinental, but it is the self guided and unsupported aspect of it that grabs me. The thought of being guided as part of a group through something like that doesn't inspire me.
Also this
"It creates a fatigue that can last for weeks, even months, after crossing the finish line."
I also think the author was over absorbed in the challenge/numbers, Jared Gruber who also rode it, obviously took the time to stop and compose the photos in the article which are fantastic.
