Mount Rainier Speed Record Shattered on Skis Last Week For a long time, Argentine mountain guideย Willie Benegas owned the Mt. Rainier speed record. ย Itโs classically recorded from the Paradise parking (5,400 feet) lot to the summit (14,411 feet) and back via the Disappointment Cleaver route. ย Willie ran up and ran down after being acclimatized to the Himalaya and did it in 4 hours and 40 minutes, which is insane.
