Dean Potter reports ascent time of 1h19m, RT time of 2h17m52s, via a non-standard route, May 3, 2015.
Reporting on his Facebook page, Potter said "It's amazing what can happen with the hybridization of Outdoor Arts such as trail running and climbing. Thanks for the inspiration Scott Jurek!" His route is sketched below (looks like the standard route was used for the descent).
Bill Wright adds some comment on the ascent route: "An old hiking guide I have described an old route up to a lookout up there from which you can see five world-class waterfalls: Upper and Lower Yosemite Falls, Nevada and Vernal Falls, and that the falls - Illiouwet or something like that. It's so steep that it isn't maintained or advertised by the Park anymore, much like the old Cables route on Longs and the Lady Mountain route in Zion. Of course, you have to solo the 6-7 pitch 5.7 of Snake Dike via this route. As that is holdless friction climbing, you don't want to be caught in any rain."
