The record for the WT might be still held by John Stamstad in September 2003 of about 24 hours. I did the 105 mile version from the NW entrance in 3 days in late July 2008 and that was no big deal carrying a 17 lb pack with about 20+ miles on snow. If I was not doing the Kautz Glacier /Kautz Headwall the end of July, I would join you.
