I read some accounts and photos from this recent Borah Peak speed climbing record of Dan Howitt (Hood River, OR resident). Highest point in Idaho 12,668 feet elevation. Done on the Standard Route, aka Southwest Ridge. The speed climb from start to top is 5,400 feet over 4 1/2 miles. A map of most of route
I'm looking for more details but I find Dan Howitt's time was 1:42 and some seconds.
It was official meaning there were people timing. Hired by him.
I searched for credible information and found this links with some things on Howitt.
Hood River News article interviewing Howitt's Mt. Hood record timer-
"OR Peak Adventures owner Joe Whittington http://www.oregonpeakadventures.com/staff.htm
, and guide John Waller http://www.uncagethesoul.com/
, timed another Hood speed climb from Government Camp to Summit to Government Camp. 2h:58m up and 4h:47m rountrip (no glissading). Start/finish in downtown Government Camp on E.Meldrum/Gov't Camp Loop Road. First person to do this specific speedclimb since Gary Leech in 1936. First in 100+ year Mt. Hood history to obtain official records. Leech did 2h:36m to the summit, but unofficially. His descent was reported at 49 minutes with mostly glissading."
