223 Miles in Two Days and Sixteen Hours
Joe McConaughy took the John Muir Trail supported record off Francois D'Haene on his third try, and took nearly three and a half hours with it.

Joe McConaughy, 33, of Seattle, ran the 223-mile John Muir Trail in two days and sixteen hours. That is three hours and twenty-six minutes faster than the men's supported fastest known time Francois D'Haene set in 2017, a mark that had stood untouched for nearly a decade.
It was McConaughy's third attempt at it. The JMT runs the spine of the High Sierra, over Forester Pass and up Mount Whitney, most of it above 8,000 feet, and it does not forgive a bad night.
Three hours and twenty-six minutes taken off a record that had survived since 2017.
