An exceptional encounter with one of the most fascinating figures in ultra-endurance

Creator of the legendary Barkley Marathons, Gary "Lazarus Lake" Cantrell has become a true legend in the world of trail running over the decades.

The man behind the race considered one of the most extreme, secretive, and fascinating in the world will be exceptionally present in France, particularly in Chamonix during the UTMB, to share this moment with the public. A particularly rare appearance in France.


Who is Lazarus Lake?

Gary Cantrell, better known as Lazarus Lake, is the creator of many endurance events that have become cult classics:

  • Barkley Marathons
  • Big's Backyard Ultra

Recognizable by his famous red and black plaid shirt, Laz is known for his offbeat humor, unique vision of self-transcendence, and his ability to push athletes to explore their true limits.

His philosophy has inspired thousands of runners around the world.

Find the full program around the release of his documentary and his exceptional visit to France.


  • The documentary

    The documentary directed by Paul Mellor (Mellor&Smith) traces the unique journey of Lazarus Lake, his philosophy, and his vision of effort.

    Through never-before-seen footage, encounters, and exclusive testimonies, the film explores the man behind the myth: his relationship with failure, resilience, adventure, and human limits.

    Far more than a film about the Barkley Marathons, this documentary tells how a simple idea became one of the greatest myths in modern endurance sports.

  • LAZARUS LAKE × RAIDLIGHT COLLECTOR CAP

    On the occasion of the documentary release, discover the collector's cap inspired by Lazarus Lake's famous red and black checkered shirt.

A story of friendship

The story between Benoît Laval and Lazarus Lake began on the trails of the legendary Barkley Marathons. In four participations, Benoît achieved the feat of completing five loops of this legendary race. Over the years, a true friendship developed between the two men, sharing the same vision of adventure and self-transcendence. Laz has also come twice to Chartreuse, notably contributing to the creation of the Chartreuse Terminorum and the first Backyard Ultra organized in France.
