This is the story of Md. Imtiaz-Bin-Faruque Bhuiyan and Mostafijur Rahman. Two endurance athletes with one shared obsession: triathlon.
Imtiaz works as the Assistant General Manager at Fiber@Home. And Mostafijur Rahman is a Bangladeshi Triathlete, Ultra Runner, First Responder, and Social Worker who actively teaches swimming to underprivileged children and promotes drowning prevention initiatives. Office by day, endurance training by dawn. “Triathlon is my hobby, but also my lifestyle,” says Imtiaz. “I swim, cycle, and run. That’s my world.” Mostafijur adds a softer truth. “I have loved swimming since childhood. I never stopped.”
Mostafijur’s journey began early. School days were not always kind. He recalls being disqualified twice in school sports. He was small. Coaches overlooked him. Still, he kept going. Later came a 13-day freestyle course at the Bangladesh Naval Academy. That changed everything. “After that course, I never stopped swimming for 23 years,” he says.
Imtiaz’s story followed a different path, but the same direction. He built a career in finance and still trained like an athlete. He calls himself a “four-occupation man.” Accountant, manager, athlete, and always a learner. A busy life. But somehow, it works.

Both athletes explored many sports. Triathlon. Duathlon. Marathon. Ultramarathon. Even Bangla Channel Swim. Imtiaz says, “This sport shows your real progress. You can measure everything.” Unlike cricket or football, there are no hidden stats here. Only distance, time, and pain.
Swimming in open water becomes the first challenge. Dhaka has pools. But not the kind that prepares you for rivers, seas, or chaos. Then comes gear. Expensive, limited, and mostly imported. A bike is not just a bike. It is survival equipment. And life does not pause for training.
Ironman 70.3 is not just any race. It is a global obsession. It started in Hawaii in 1978. Navy SEAL training experiments turned into a legend. Swim 1.9 km. Cycle 90 km. Run 21.1 km. Finish within the cut-off time or go home with regret. Simple rules. Brutal reality.
Imtiaz explains it clearly. “If you finish, you become an Ironman. That title means everything in this sport.” Mostafijur agrees. “It is like Everest for triathlon.” And just like Everest, not everyone returns the same. The big break came at Malaysia’s Desaru Coast in 2024. A half Ironman event.

A global qualifier. 3,500 athletes. Only a few slots for the Ironman 70.3 World Championship. The course was brutal. Rolling roads. Heat. Open sea swim. Their competition was fully equipped professionals, while they didn’t have any top-tier gear. Still, they pushed. They trained early. They studied the route. They adapted. Imtiaz smiles, “We thought we may not finish. But we did.”
Then came the shocking news. They both qualified for the Ironman 70.3 World Championship. A moment of disbelief. Then the celebration. But panic followed soon. Because qualification is one thing, registration is another nightmare.

The World Championship took place in Marbella, Spain. High elevation. Thin air. European elites everywhere. “This is not Bangladesh,” Imtiaz says. “Everything felt different.” The course was extreme. 1,750 meters (5,741 feet) above sea level. Rough climbs. Even breathing felt expensive.
Athletes from around the world lined up. Tall, lean, trained for years. And then came two men from Bangladesh. Not perfect equipment. Not ideal training grounds. But absolute determination.
The swim was in Mediterranean water. Calm but cold. The bike had monstrous climbs, and the run tested mental survival. And yet, they finished. Mostafijur laughs, “We were not favorites. But we were finishers.” They completed it in around 6 to 7.5 hours.

Finishing did not end the journey. It changed everything. They also completed the Bangla Channel swim. They planned more Ironman races. Imtiaz is heading toward the Italian Ironman. Mustafijur toward New Zealand.
They believe Bangladesh is entering a new era of endurance sports. More runners. More triathletes. More dreamers. Their advice is simple. Enjoy the journey. Not just the result. “You are not racing others,” Imtiaz says. “You are learning your body.” Mustafijur adds, “It is not solo. It is a community.” Training is evolving. Communities are rising. But discipline still matters most.
Ironman is not just swimming, cycling, and running. It is life under pressure. Broken limits. And sometimes, unexpected victories. From office desks to Spain’s mountains, their journey proves one thing. Ordinary people can do extraordinary distances. If they refuse to stop. And maybe that is the real Ironman story.
