I decided to race in during my Mt. Clark roundtrip FKT attempt, to see if I could also do the ascent FKT! Please see the full write-up on the roundtrip page.
My Gaia app crashed at 4:11:22 as you can see from the gpx file, just below the summit. I was also timing the run on my stopwatch, and hit the summit 5 minutes later at 4:16:36 as you can see in the photo (the seconds at covered by the lap number in the picture). I hope this suffices!
Yosemite never disappoints. The superb rock quality, spectacular position, and rugged cross country all made for an unforgettable experience!
