Six full Ironman triathlons. Twenty half Ironman races. Numerous ultra-marathons and 200-mile bike rides. Santosh Karmacharya’s achievements read like a modern legend. Yet, beneath these accolades lies a deeper drive—to push his body and redefine the limits of human potential. 

Following a “less-than-impressive” finish at the Ironman World Championships in Australia this past summer, Karmacharya was determined to redeem himself. 

In an interview with 8850media, Karmacharya, who runs a fitness studio Om Namo Center in Belmont, Massachusetts, explains, “I’ve always believed that limits are meant to be challenged.

“This isn’t about medals or finishing lines. It’s about honing my craft and pushing my boundaries.” 

777 Challenge

This relentless drive led him to the Great World Race: seven marathons on seven continents in seven days. Drawn by its promise of an unforgettable, all-inclusive adventure, the idea of the race first came to him in 2022. But it also comes with a hefty entry fee of $52,000. After waiting for two years, he took the plunge.

The 2024 edition featured 54 competitors from 15 countries, with a punishing itinerary spanning Antarctica’s freezing cold to Cartagena, Colombia’s scorching heat. Beginning in Wolf’s Fang on November 14, the runners aimed to reach Miami by November 20, testing their physical and mental endurance. 

The second stop was Cape Town, South Africa, followed by Perth, Australia. A unique aspect of the event was Istanbul, Turkey, hosting both the Asian and European legs. After completing the Asian marathon, participants crossed the Bosphorus Bridge to compete in the European race. 

The 49-year-old athlete describes the first two marathons in Antarctica and Cape Town as the toughest. “Battling an eight-hour time difference and minimal sleep in Antarctica, I struggled to find my footing,” he says. 

Polar Opposites

The transition from Istanbul’s brisk 50°F to Cartagena’s sweltering 92°F with 90 per cent humidity was overwhelming. “Twice, I was on the brink of collapse, my training and resilience pushed to their limits,” he recalls. “Supporters revived me by pouring water on my back and placing cold cloth on my forehead.” 

His disciplined training regimen and remarkable resting heart rate of 38-39 bpm fueled his resilience and rapid recovery. He secured sixth place among 29 male competitors, with a total time of 24 hours, 35 minutes, and 57 seconds. David Kilgore (23:40:42) and Hillary Kupish (22:25:25), both from the US, won the men’s and women’s races, respectively. 

True triumph lies not in numbers but in the structure and balance he has created. He says, “Every accomplishment is a brick in the foundation I’ve built through relentless dedication.” 

His daily routine revolves around a strict schedule that balances family, work, and training. As dawn breaks over Boston, he begins his day by gliding through water, pounding the pavement, or cycling with perfect cadence. He gave up social drinking and television long ago to focus on his goals. 

Discipline and Joy

His extraordinary success is grounded in two principles: discipline and joy. “Discipline allows me to relax when I’m not training,” says the father of two boys and devoted husband of 22 years. 

And joy? 

“Joy lies in the process—embracing challenges and showing up consistently—qualities that define the Nepali spirit.” 

Born in Lahan, a small town in eastern Nepal, Karmacharya’s journey to endurance sports began far from its realm. His family moved to Kathmandu when he was two. Growing up in an inter-caste household, he embraced inner strength and perseverance—traits that later shaped his approach to sport. 

His first love was basketball, a passion he nurtured in high school in Kathmandu and carried with him to the US. The tragedy of the 2013 Boston Marathon bombing marked a pivotal shift, though. The blast on April 15 claimed three lives and injured hundreds near the finish line.

Inspired by the city’s spirit of defiance and healing, he took up running—a decision that sparked a journey of self-discovery, and athletic achievement. “I signed up for the Boston Marathon after the bombing,” he recalls. 

Transformation

By 2014, he discovered a new purpose, becoming an international endurance athlete. He began running, swimming, and cycling—activities that transformed him into an ultra-athlete. Each mile was a step toward healing, discovery, and achievement. 

Running introduced a new kind of challenge, requiring not only strength but also precision and patience. “It took me three years to correct my running form,” he says. 

Swimming presented an even greater challenge. “I didn’t know how to swim until my son was two years old. I learned alongside him,” he admits. Gradually, he mastered the skill, motivated as much by his child as by his ambitions. 

Cycling came next. Initially a commuting necessity, it evolved into a key part of his fitness routine, eventually leading him to triathlons. 

Pushing Forward

In 2017, Karmacharya became the first Nepali athlete to complete a full-distance Ironman. He completed the Ironman Louisville race in 12 hours, 7 minutes, and 45 seconds—an achievement he still holds as one of his proudest. Endurance sports have taught him that life’s greatest rewards often lie in the effort itself. 

Surrounding himself with positive influences helped him shift his mindset. “I moved from asking, ‘Why can’t I?’ to ‘How can I?'” says the Om Namo health coach. This subtle yet powerful change in mindset enabled him to approach challenges with curiosity and determination rather than doubt. Om Namo employs 12 staff members and offers services in alternative medicine, including acupuncture, bodywork, nutrition, strength training, yoga, and counselling. 

As 2025 approaches, Karmacharya remains resolute in embracing fresh challenges. His goal is to redefine the boundaries of possibility, inspiring others along the way. Whether it is in sports, career, or personal growth, he encourages others to believe in their potential and never stop pushing forward. He says, “It’s never too late to turn a spark into a flame and achieve the extraordinary.”
