If anyone has a shot at becoming the first American man to win the Ultra-Trail Mont Blanc, it’s gotta be Jim Walmsley.

A new documentary from HOKA and Wahoo, “Walmsley Part 1,” follows the ultrarunner on his quest to win the Ultra-Trail Mont Blanc (UTMB).

Walmsley’s list of accomplishments runs long. The Colorado-based runner has won the JFK 50 and the Western States 100 not once, not twice, but three times each.

He set the course record at the 2018 Western States 100, only to beat it again in 2019 by shaving 21 minutes off his previous time. Also in 2019, Walmsley ran the world’s fastest 50-miler, eking it out in 4 hours, 50 minutes, and 7 seconds.

And yet, the UTMB is a notoriously demanding race and formidable opponent — even by Walmsley’s standards. Encircling the highest mountain in the European Alps, the ultramarathon spans 106-plus miles and gains 32,940 feet in total elevation.

Becoming the first-ever American to win the UTMB men’s race requires Walmsley to uproot his life, buckle down, and train harder than ever before.

But will it be enough?
