Interesting information about the record climbing times in the Mount Shasta Museum.
John Muir for example needed 4 hours 10 minutes from the timber line, about 40 minutes above Bunny flat.
The current fastest known time from Horse Camp to Summit seems to be 1 hour 38 min, set in 2012.
Another remarkable record are the 37' 572 vertical feet (11'450m) within 24 Hours, climbing Mt. Shasta 6 Times.
Even stranger: In 1903, Tom Watson took the Horse "Jump Up" to the summit - sadly, the horse had to be killed after the too strenous expediton.
