Wow … It Seemed Like Thin Air is truly a monster of a workout and a veritable “abomination of climbing” (from the workout description).
I remember doing Kitchen Sink during the 2018 (right?) ToS and how tough that one was with the endless short, high intensity stuff from The Shovel, etc. and so I expected similar suffering on ISLTA given the similar IF. Well, ISLTA is equally tough in my opinion, but for a Pursuiter like me, those long intervals (especially the 40 minute climb of Mount Sufferlandria!) made for some particularly glorious suffering!
Have you done ISLTA? What were your impressions?
