Zach Miller burst onto the ultrarunning scene with a stunning and surprising win at the 2013 JFK 50 Mile Race. Since then, he’s gone on to race in some of the biggest international mountain ultramarathons in the world, including his biggest “white whale” of them all: the Ultra-Trail du Mont-Blanc (UTMB®). Since leading for most of the 100-mile race back in 2016 only to crash and burn in the final 15 miles, Zach has returned year after year in his attempt to become the first American male to win and for him personally, to be able to “solve the puzzle”.
