The documentary was awarded the Academy Award for Best Documentary Feature at the 2019 Oscars and has received numerous international accolades including BAFTA and Emmy Awards. It explores themes such as climbing sport, human limits, risk management, and mental preparation through academic, athletic, and visual storytelling, and is regarded as a landmark work in cinematic technique and documentary methodology.

The climb was recorded by National Geographic and comprehensively documented in the 2018 film Free Solo. The film won the Academy Award for Best Documentary in 2019. Honnold’s preparation and ascent have been analyzed across various scientific and cultural platforms. The documentary has introduced the physical and psychological dimensions of this climbing discipline to a broad audience.

Free solo climbing is the practice of ascending a rock face alone, without ropes, harnesses, or any protective gear. Due to the fact that even the smallest mistake or fall can result in serious injury or death, it is considered the most dangerous form of climbing. Although praised as the “purest” form of climbing, it is also extremely hazardous, and only a handful of elite climbers have succeeded in this discipline.

Free soloing on long rock faces hundreds of meters high demands not only exceptional physical ability but also superior mental resilience and the capacity to control fear. Climbers like Honnold minimize these risks by meticulously studying and memorizing routes in advance and undergoing years of training to prepare both body and mind. Nevertheless, due to the inherent lethal risks of free solo climbing, many regard this form of climbing as an activity with “no room for error.”

Alex Honnold (born 1985) is an American rock climber internationally renowned for his achievements in free solo climbing. Honnold demonstrated exceptional talent from a young age and quickly rose to become one of the world’s leading free climbers, gaining widespread attention through his free solo ascents beginning in the late 2000s. While he has also achieved success in traditional roped climbing, it is his free solo performances that have brought him fame.

Chronological list of Honnold’s notable free solo achievements:

• 2007 (September) – Climbed the Astroman (5.11c) and Rostrum (5.11c) routes in Yosemite back-to-back in a single day. This made him the second person since Peter Croft in 1987 to ascend both classics without ropes in one day.

• 2008 (April 1) – Free soloed the famous Moonlight Buttress route in Utah’s Zion National Park (approximately 5.12d difficulty, 300m) without ropes. When first announced, many assumed it was an April Fools’ joke, but once confirmed, it sent shockwaves through the climbing community.

• 2008 (September 6) – Completed the Half Dome (Northwest Face, 5.12a, ~600m) route in Yosemite as a free solo. This ascent brought Honnold international recognition and was featured on television programs such as 60 Minutes.

• 2012 (May) – Completed the “Triple Crown” of Yosemite Valley—Mount Watkins, El Capitan, and Half Dome—in consecutive order within 18 hours and 50 minutes, with approximately 90% of the route climbed as free solo. During this effort, he also soloed Half Dome again, setting a record time of about 1 hour and 22 minutes.

• 2014 (January) – Free soloed El Sendero Luminoso in El Potrero Chico, Mexico (15 pitches, ~500m, 5.12d) in approximately 3 hours.

• 2014 (Throughout the year) – Completed free solos of highly technical and difficult short routes in Yosemite, including Heaven (5.12d) and Cosmic Debris (5.13b). That same year, he also free climbed The Phoenix (5.13a), a crack route considered a milestone in traditional climbing history, without ropes.

• 2016 – As part of his preparation for the El Capitan ascent, he free climbed the West Face (5.11c) and East Buttress (5.10b) routes on El Capitan without ropes. Although these routes are not on the main face of El Capitan, their free solo ascents were significant demonstrations of Honnold’s capabilities on long walls.

• 2017 (June 3) – Free soloed the El Capitan Freerider route (5.12d/13a, ~900m, 33 pitches). His ascent of this 900-meter vertical granite wall without any safety ropes on June 3, 2017, in Yosemite National Park made him the first person in history to accomplish such a feat. This climb became the subject of the Oscar-winning documentary Free Solo, drawing international attention and cementing Honnold’s name in both the climbing world and the general public consciousness.

Honnold’s achievements on this list have raised the standard for free solo climbing significantly. While free solos of shorter routes rated 5.12 or lower were known before him, Honnold distinguished himself by consistently achieving free solos on routes of high difficulty and great length.

Freerider is one of the most famous and challenging free climbing routes on El Capitan in Yosemite National Park. First climbed in 1995 by Alexander Huber using variations of the 1961 classic Salathé Wall route, Freerider consists of approximately 33 pitches and has a difficulty rating of 5.12d/5.13a according to the traditional Yosemite grading system.

This means the hardest moves on the route are at the 5.13a level (approximately 7c+/8a in the French system). The most critical section of Freerider is the “Boulder Problem,” a short rock passage located at pitch 23 near the summit, which contains an extremely technical sequence of moves rated at approximately 5.13a. Additionally, the route features physically demanding crack and offwidth sections such as Enduro Corner and Monster Offwidth, friction-dominated slabs like Freeblast Slab with almost no handholds, and delicate traverses.

Freerider is a long big wall route that tests a climber’s finger strength, footwork, balance, flexibility, and endurance. Some sections of the route have so few natural holds that the climber must use a technique called “smearing,” pressing the climbing shoe against the rock surface to ascend as if walking on glass.

Alex Honnold had nurtured the idea of free soloing El Capitan for years and entered an intensive preparation phase between 2016 and 2017 to realize this goal. He described this endeavor as “an eight-year dream and a one-and-a-half-year practical preparation.”

^{Free Solo (2008), (}National Geographic⁾

During preparation, Honnold repeatedly climbed the route with ropes, memorizing every move, exploring alternative variations for dangerous sections, and planning minor route modifications when necessary. For example, he identified safer lines by deviating slightly from the original route where he felt certain moves were insecure. He noted that because free soloing does not require ropes, such small deviations are possible and, in a sense, “liberating.”

In the fall of 2016, Honnold attempted a trial run but concluded his preparation was incomplete and abandoned the attempt. In November 2016, due to colder weather and an injury to his foot, he cut short an early solo attempt on Freerider, feeling uncomfortable on the “Freeblast” slab section in the lower part of the route.

When Honnold returned to Yosemite in spring 2017, he first explored other routes on El Capitan with Canadian climber Sonnie Trotter before refocusing entirely on Freerider. He conducted roped training to find alternative passages through sections he deemed dangerous; for instance, he discovered a different line on the Heart Ledges that bypassed a delicate slab move, reducing the difficulty from 5.11c to 5.10c.

^{Alex Honnold Preparation Process (}National Geographic⁾

As June 2017 approached, Honnold’s preparation reached its peak. With meticulous attention to detail, he rehearsed every critical move on the route countless times, logged all progress in a training journal, and prioritized finger strength and endurance training to reach peak physical condition. A few days before the climb, he and close friend and renowned climber Tommy Caldwell completed a speed ascent of Freerider with ropes, finishing in 5.5 hours and breaking their own speed records.

Caldwell emphasized Honnold’s peak performance during this rehearsal, saying, “Alex was on fire—I’ve never seen him climb that well.” As a final preparation, Honnold climbed to the summit a few days before the attempt, then rappelled down the route to check whether his chalk marks were still visible and whether recent rain had wet the rock surface. Fortunately, the rock was completely dry and the marks remained; all that remained was mental rest and focus for the historic climb.

On the morning of June 3, 2017, American climber Alex Honnold, known for his free solo ascents, decided to climb the famous granite face of El Capitan without any safety ropes or climbing partner. Early that morning, after waking up in his minibus at a campsite in Yosemite National Park, he ate breakfast consisting of oatmeal and fruit. He then walked to the base of El Capitan.

Honnold prepared for the climb with only a red T-shirt, shorts, climbing shoes, and a chalk bag attached to his waist; no other technical equipment was carried. He began climbing at 5:32 a.m. He aimed to pass the most technically demanding section of the route, the “Boulder Problem,” before the sun reached the rock face, to avoid adverse effects from thermal expansion of the granite.

Alex Honnold progressed continuously along his pre-determined route during the first hundred meters of the climb. This section featured long crack pitches of moderate technical difficulty and physically demanding passages such as the “Monster Offwidth.” Honnold stated that to maintain mental control during these sections, he redirected his focus toward mundane thoughts, thereby reducing emotional tension.

Although he was alone during the climb, there were spectators near the base and observers at a distance. However, Honnold’s level of concentration remained unaffected by these external factors. According to his own account, at the moment he realized the climb was unfolding as planned, he experienced an internal sense of joy, which he expressed briefly with a smile. This demonstrates his ability to maintain psychological balance under extreme risk.

After successfully navigating the critical lower and middle sections of the route as planned, Honnold reached the most difficult section: the “Boulder Problem.” This short passage contained very few small holds and required the climber to support their entire body weight through extreme technical movement. At this point, Honnold executed a movement he had practiced countless times during rehearsals: placing one foot on a narrow edge and pushing sideways (some climbers describe it as a “karate kick”) while gripping small ledges with his hands to complete the most critical move. After overcoming this threshold, only a few more challenging pitches remained, such as the steep crack system known as “Enduro Corner,” which Honnold ascended with steady control.

The difficulty decreased in the final sections; as Honnold neared the summit, he increased his pace and sprinted up the final flat slab pitches. At 9:28 a.m., 3 hours and 56 minutes after he began, he reached the summit of El Capitan, becoming the first person in history to climb this massive rock wall alone and without ropes. Members of the documentary crew and several witnesses at the summit celebrated his achievement as he stepped safely onto the top. The entire ascent was recorded by the National Geographic team; even the cameramen descending from above struggled to keep pace with Honnold’s speed. After reaching the summit, Honnold described his emotions as “fulfilling the biggest dream of my life.”

Honnold’s free solo ascent of El Capitan generated widespread reaction both within the climbing community and the general media. Worldwide news agencies reported the event under headlines such as “Made history by climbing one of the world’s largest monoliths without ropes.” The climbing magazine Alpinist described Honnold’s achievement as “undoubtedly the greatest free solo climb of all time,” emphasizing that it demonstrated “a level of mastery unprecedented in climbing history.” The American Alpine Journal responded to the event with a single word: “Speechless.”

Renowned climber Conrad Anker described Honnold with the words, “Respect. His life’s purpose has been realized.” Honnold’s close partner Tommy Caldwell defined the climb as “one of the highest peaks of mental control ever achieved in any sport.” While many in the climbing community regard Honnold as an idol, the event also sparked debate due to the inherent risks of free soloing. Some observers expressed concern that publicizing such a dangerous practice might encourage others to take unnecessary risks.

Honnold’s achievement also attracted significant mainstream media attention. Publications such as The New York Times, NPR, and The Guardian featured him on their front pages. A year after the climb, the National Geographic documentary Free Solo, which chronicles Honnold’s preparation and ascent, premiered in September 2018. Directed by Jimmy Chin and Elizabeth Chai Vasarhelyi, the film intimately documents both Honnold’s physical journey and psychological state, aiming to reveal the inner world of climbing. Free Solo won the Academy Award for Best Documentary Feature in 2019, becoming the first climbing film ever to achieve such acclaim.

The documentary achieved unexpected box office success and introduced the sport of climbing to a vast audience unfamiliar with it. In her Oscar acceptance speech, director Chai Vasarhelyi said, “This film is for anyone who believes something is impossible,” highlighting the universal inspiration of Honnold’s feat of pushing human limits. Due to the impact of the documentary and media coverage, Alex Honnold became a legend; his name is now known not only among climbing enthusiasts but also the general public. In fact, in English, the verb “to honnold” has entered colloquial usage as a humorous term meaning to be in a precarious, unprotected position at a great height.

This wave of international recognition brought Honnold numerous awards and honors. In 2018, the prestigious mountaineering award Piolet d’Or (Golden Ice Axe) jury awarded Honnold a special mention for his 2017 ascent, stating that the Freerider climb represented “an exceptionally rational and meticulously planned ascent” and that Honnold had reached “a level of mastery likely unmatched in the history of rock climbing.” Also in 2018, the American Alpine Club awarded Honnold the Robert and Miriam Underhill Award for excellence across all disciplines of climbing.

Alex Honnold attributes the key to success in extremely risky disciplines like free solo climbing to the ability to manage fear. In interviews following his El Capitan solo, he emphasized that fear is natural in this form of climbing, but succumbing to it during the ascent provides no benefit: “I am certainly aware of the danger, but feeling fear while on the wall does nothing to help my performance; therefore, I set it aside and focus on the task at hand.”

Honnold’s calmness has attracted the attention of scientists; brain imaging studies have revealed that the amygdala region, which typically activates in response to threats in most people, shows unusually low activity in Honnold’s brain. Whether this trait is innate or developed through over two decades of climbing experience and gradual exposure to fear remains scientifically undetermined. In his own words, over the years he has expanded his comfort zone, turning what once seemed “crazy” goals into achievable ones.

Honnold does not view free solo climbing as an impulsive or reckless risk, but rather as the pinnacle of a carefully calculated strategy. Thanks to years of preparation, countless decisions made and rehearsed mentally in advance, he claims that during the actual climb, he operates with a “blank mind,” focusing solely on the movement of the moment.

This approach has been widely admired in the climbing community. His close friend Tommy Caldwell emphasized that what made Honnold’s success possible was not his incredible physical strength, but his mental discipline and control of fear. Another renowned climber, Adam Ondra, stated that the courage and mental resilience required to free solo a route like Freerider are “harder than climbing a 9a (5.14d) sport route with ropes.”

When explaining his perception of risk, Honnold stresses that although his climbs may appear lethal to outsiders, he systematically minimizes these risks through preparation. He says, “Instead of worrying about the possibility of death, I do whatever is necessary to prevent it,” implying that the most important part of free solo climbing occurs during preparation. Indeed, Honnold describes experiencing a different state of consciousness during the climb—a mind focused entirely on the task, detached from emotion. In this sense, his philosophy has been compared to Stoicism: controlling actions, not emotions.

Some neuroimaging studies on decision-making during free solo climbing have shown that Honnold’s amygdala responds far less to external stimuli than in other individuals. This has been interpreted as evidence of heightened mental stability and reduced threat perception during free soloing. It remains scientifically unresolved whether this trait is innate or developed through prolonged exposure and training.

Alex Honnold’s free solo ascents have demonstrated the extent to which human limits—both physical and mental—can be stretched, redefining the concepts of risk and achievement in this field. His 2017 ascent of El Capitan stands as the culmination of this journey in history.
