This below description is copied from Dan Kraft's FKT on the ascent of this route. The old proboards didn't make it the distinction between ascent and round trip quite as clear, but as he discusses his roundtrip time, it seems to me he intended to claim both of them. In looking at his Strava, it appears that he ran a few miles warm up, that looked to be 0:20:05 and I subtracted that from his total elapsed time of 2:28:32. I then added 15 seconds because it looks like he stopped his watch a hair shy and that seemed more than enough for him to cross the parking lot. As of this submission in 2022, Dan's time is still faster than any time listed on the round trip strava segment.

I ran Mt. Defiance to celebrate my birthday on October 18, 2014.
Made the ascent in 1:12:14 and the roundtrip from the parking lot was approx. 2:05.

GPS had a bit of trouble there at the end.
