10 Must-Watch Running Documentaries

Finding Traction (2014)

This documentary follows Nikki Kimball, an ultra-trail legend, as she attempts to break the women’s record on the Appalachian Trail. Over the route’s 435 kilometres, independent filmmaker Jaime Jacobsen captures both the athletic feat and the mental toll, along with the tensions within Kimball’s team. The film shows the moments of doubt without flinching, far removed from the usual heroic narrative. Finding Traction won awards at venues including the Banff Mountain Film Festival. It is a raw, intimate documentary that explores the human side of performance as much as the performance itself.

Transcend (2014)

Transcend tells the true story of Wesley Korir, a Kenyan marathoner who rose from poverty in the Rift Valley to the global elite before entering politics. The documentary follows his journey from Kenyan roads to international marathons, as well as his efforts to give back to his community. Korir is best known for winning the 2012 Boston Marathon in 2:12:40, just months before embarking on a political career. The film also reveals the other side of the Kenyan dream, so often idealised from afar.

Run Free: The True Story of Caballo Blanco (2014)

This documentary pays tribute to Micah True, aka Caballo Blanco, a mythical ultra-running figure and the inspiration behind Christopher McDougall’s book Born to Run. It explores his search for freedom, his rejection of certain aspects of modern running and his deep connection with the Tarahumara people. The film takes an unexpected turn with Micah’s tragic disappearance in New Mexico in 2012. More than a film about running, it is a welcome reflection on what running means. Inspiring and unforgettable.

The Barkley Marathons: The Race That Eats Its Young (2014)

Probably the most cult running documentary ever made. It plunges viewers into the sometimes absurd, often cruel world of the Barkley, a secretive race dreamed up by the enigmatic Lazarus Lake. The start is announced with a conch shell, there is no official website or social media presence, and finishers are vanishingly rare. The race has built its legend on raw, almost brutal authenticity. Its funny yet relentless tone won over audiences far beyond the running world. The film picked up numerous festival awards and helped turn the race into a global legend, one that remains very real. As long as Lazarus is keeping watch…

Where Dreams Go to Die (2012)

We stay at the Barkley for this documentary, which follows Gary Robbins in his attempt to finish the race. In a ruthless storyline that ultimately lives up to the Barkley legend, the Canadian runner crosses the line just seconds outside the time limit. He later described it as “the most painful experience of my life”… Ethan Newberry’s documentary is as harsh as the Barkley itself. A cinematic gem cherished by fans of the race.

Free to Run (2016)

Part history lesson, part manifesto, Free to Run traces running’s emancipation from the 1960s onwards, from New York to the Alpine trails. Swiss filmmaker and runner Pierre Morath delivers a beautiful documentary and a genuine tribute to the sport. Marathons.com was lucky enough to speak with the director in January 2025. The film shines a light on the early figures who shaped running, including Kathrine Switzer and Steve Prefontaine. Screened and awarded at several international festivals, it has plenty to offer beyond the running community.

Running the Sahara (2007)

Narrated by Matt Damon, this documentary recounts the extraordinary journey of Ray Zahab, Charlie Engle and Kevin Lin as they cross Africa on foot. Over 111 days and more than 6,000 kilometres, they travel from the Atlantic Ocean to the Red Sea through six countries: Senegal, Mauritania, Mali, Niger, Libya and Egypt. The journey nearly came to a halt in Libya for the three runners and the film crew after diplomatic problems arose.

Spirit of the Marathon I & II (2007 / 2013)

These two films tell the story of the Chicago Marathon through a wide range of runners, from elite athletes to anonymous amateurs. The first instalment was warmly received by audiences and the American press when it came out in 2007. Several participants experience their first finish under the watchful eye of Jon Dunham, who has made several running documentaries, including Boston (2017), which could easily have made this top 10. The second film broadens the perspective to other legendary marathons. Both have become classics.

Breaking2 (2017)

Produced by Nike, Breaking2 documents the attempt to run a marathon in under two hours. The film follows Eliud Kipchoge, Lelisa Desisa and Zersenay Tadese as they pursue an ultra-scientific approach to performance. The American brand presumably hoped for more from the film. It was meant to capture the long-awaited breakthrough, but Kipchoge fell just 25 seconds short of the target, foreshadowing his historic, though unofficial, achievement two years later. Part branded documentary, part media event, the film inspired as much debate as admiration.

Unbreakable: The Western States 100 (2012)

This documentary revisits the legendary 2010 edition of the Western States 100, when four ultra-running legends lined up: Anton Krupicka, Geoff Roes, Hal Koerner and Kilian Jornet. Three of them would finish on the podium in an extraordinary edition, with suspense rarely matched since. After more than 160 kilometres of racing, just six minutes separated the winner, Geoff Roes, from runner-up and inimitable rival Anton Krupicka. Unbreakable is often regarded as the best film ever made about ultra-trail. It played a lasting role in establishing the Western States as an international icon.
