Thanks for pointing this out. Actually, that person provides nonsensical times with the RT faster (1:30) than the ascent (2:00), and those times are obviously approximate. Plus, we will not attribute an FKT without an actual name. The FKT on 14ers.com appears to be Jeff Valliere's 1:39:57 RT from 2010. Checking with Jeff on that.
