On 20 June 2026, on a 400 m athletics track at the Université du Québec en Abitibi-Témiscamingue, Sylvain Sebastian Santamaria entered into a long and punishing circle.
He carried 50 kilograms: a weighted vest, two kettlebells, and the invisible burden of a message he wanted others to feel, if only for a moment. Around the track he walked, lap after lap, under a load equal to nearly half his own body weight. The ground did not change. The circle did not change. Only the body changed, gradually submitting to pain, repetition, heat, friction, and the slow arithmetic of endurance.
Atlas World Records has officially certified Santamaria for the Fastest Marathon Distance Walked While Carrying a Fixed 50 kg Load, with a verified time of 10 hours, 58 minutes, 00 seconds.
The attempt had first been imagined as a 12-hour loaded walk. But somewhere deep into the ordeal, after roughly six hours, Santamaria understood that something more precise and more widely understood was becoming possible. The marathon distance, 42.195 km, was no longer an abstraction. It was out there on the same track, waiting inside the repetition.
“The marathon is an iconic distance that everyone understands,” Santamaria said. “Completing a marathon while carrying 50 kilograms tells a much stronger story than simply walking for twelve hours.”
A Burden Chosen for Meaning
The event was organized to raise funds and awareness for La Ressource pour personnes handicapées en Abitibi-Témiscamingue, an organization that supports people with disabilities in the region.
Santamaria works closely with people with disabilities as a physical trainer and coach. The weight he carried was not chosen only for athletic difficulty. It was chosen as a symbol. Fifty kilograms, nearly half his body weight, became a physical metaphor for the additional challenges many people with disabilities confront each day.
“It was my personal way of symbolizing the extra challenges that many people with disabilities face every day,” he said. “While it can never truly represent their experience, I hoped it would encourage people to reflect on their resilience.”
Of course, no symbolic weight can fully imitate another person’s life. Santamaria understood this. The load was not a claim of equivalence. It was an act of attention. A way to say: look closely at the strength that often goes unseen.
During the attempt, supporters gathered at the track. Some walked with him. Among them was Rémi, a young boy with a disability whose story helped inspire the event.
“Seeing him and others with disabilities walking alongside me gave me incredible motivation,” Santamaria said.
The Geometry of Suffering
The track was simple. Four hundred meters. A loop. A place designed for motion, but also for return. Every lap brought Santamaria back to the same point, carrying the same weight, facing the same question: continue, or stop?
His preparation had lasted six months. He trained his grip, his core, his legs, and his tolerance for loaded distance. He planned his pace carefully, aiming for approximately 4 minutes and 30 seconds per lap. He ate pretzels and fresh fruit. He drank about 700 ml of water with electrolytes each hour. He kept his breaks under two minutes.
But no plan can remove suffering. It can only give suffering a structure.
His feet suffered most. Blisters became severe, and the pain continued for weeks after the event. The weight pressed constantly into his shoulders, legs, and forearms. There was no neutral moment, no instant in which the body was allowed to forget.
“The weight constantly pressed on my shoulders, legs, and forearms,” he said. “Every step required effort, and there was never a moment when I forgot I was carrying it.”
Mentally, the most difficult portion came between laps 60 and 80. By then, the attempt had entered a strange middle territory: too far to feel fresh, too early to feel close to the end. The lap count rose, but the finish still seemed remote.
“The challenge felt endless,” he said. “It seemed like I wasn’t making progress, and knowing I still had many laps left was mentally exhausting.”
Still, he did not consider quitting.
“I knew it would be difficult,” he said, “but quitting was never an option.”
A Record Made Visible
Santamaria completed the marathon-distance mark in 10 hours, 58 minutes. The record was verified through video evidence, weigh-in documentation, lap-counting records, and witness materials submitted to Atlas World Records.
For him, the meaning of the achievement extends beyond the measured time. It represents more than 15 years of consistent training, but also a public gesture toward perseverance, inclusion, and service.
“I hope people realize that many limits are mental,” he said. “Regardless of your circumstances, everyone is capable of challenging themselves and achieving more than they think.”
Santamaria thanked La Ressource pour personnes handicapées en Abitibi-Témiscamingue, Gorila Fitness for providing equipment, Synergie Rouyn-Noranda, his family, friends, volunteers, and everyone who supported the challenge.
He is already considering another fundraising endurance challenge next year, possibly a heavier 400 m carry or a one-hour vehicle pull.
Whatever he chooses, the shape of the task will likely be simple. A weight. A distance. A body in motion. And, behind it all, the insistence that human limits are not fixed objects. They are boundaries that sometimes move, slowly, one painful step at a time.
