“UTMB is not conquerable by a human, it’s conquerable by the human spirit. And you need to harness the spirit in order to accomplish the goal.”

Jim Walmsley discovered ultra trail running through an unconventional journey. After participating as a track athlete in high school and college, he transitioned to the military, serving in a nuclear missile silo in Montana. He was eventually dismissed, leading him back to running, where he emerged as one of America’s top ultra trail runners.

Following impressive records at the Western States 100, Jim sought a new challenge: the infamous Ultra Trail du Mont Blanc (UTMB). Despite initial failures, he committed to enhancing his mindset and training, bringing him to relocate to France with his wife, Jess.

In 2023, Jim achieved a historic victory, becoming the first American man to win UTMB in a thrilling mid-race twist. He now joins the ranks of great American women who have triumphed in the race before him.
