Disappointment Cleaver Route roundtrip Dan Towner 5h08m ? Dan once climbed Shasta six times in a day!  
Disappointment Cleaver Route roundtrip, but not to the very summit! ?? Chad Kellogg 5h6m54s ? Via the Disappointment Cleaver Route. Chad signed the summit register, but didn't go to the tippy top. This is supposedly a 3-5 minutes further away and 50-100 feet higher.

This is bogus and since he bested Towner by barely a minute, I don't consider it the record.
Dan Howitt had claimed a speed record on Rainier and it has been highly disputed. Dan asked me to remove it from this site because he didn't feel he had proper verification. The rebuttal of Dan's climb is here.

Dan's rebuttal of the Chad's climb is here.
Disappointment Cleaver Route ascent Dan Howitt 5h08m 10/03 The route was about 1/2-3/4 of a mile longer than usual. This isn't the ascent record, as it obvious from the roundtrip times. This was Dan's first successful ascent with new third-party verifiers.
Camp Muir ascent Scot Wanek 54m 1993 From Paradise. This is 5000 vertical feet!
