On the shores of Nauthólsvík, Reykjavík, in early September 2025, the quiet beach suddenly turned lively. A muscular man, his face weary but smiling, emerged from the cold North Atlantic. That was Ross Edgley, an extreme swimmer from England, who had just completed something that sounds impossible to most, swimming around the entire island of Iceland—over 1,600 kilometers.
“This was the toughest but also the most beautiful experience I have ever lived,” he said in a hoarse voice, greeted by the cheers of his support team and the spectators gathered.
His journey began on May 17, with a target of 90 days to finish back where he started. But reality proved much harsher. Iceland’s weather would not relent. Atlantic storms forced him to stop for days at a time. Ultimately, he completed the epic swim on September 8—114 days after departure.
Every day, he divided his schedule into six hours of swimming and six hours resting aboard his support vessel. Then he plunged back into the sea, facing water temperatures between 3 and 5 °C. High waves and chilling winds were constant companions.

Prepared for the Cold
Before embarking, Edgley deliberately put on an extra 10–15 kilograms of body weight. The extra fat acted like a natural “jacket” to resist the cold of the ocean. While a wetsuit and neoprene gear helped, his body still had to adapt.
“Water this cold can incapacitate anyone in a matter of minutes,” one medical team member warned. But Edgley knew how to manage his physiology. He built his physique into a machine resilient, tough, and sea-ready.
The energy he expended each day was enormous. He consumed up to 15,000 calories per day. While swimming, he routinely ingested 120 grams of carbohydrates per hour—though his stomach often resisted. Pasta, bread, and local Icelandic food became the “fuel” for his long journey.
Without this, his body would not have lasted. But there was a cost his tongue swelled and cracked from prolonged exposure to salty water. His skin was riddled with abrasions from friction against the wetsuit. “Sometimes it felt like my body had been run over by waves,” he said, laughing faintly.
Science Behind the Adventure
This was not just a feat of endurance and record-seeking. Behind the extreme swim lay a research mission. Edgley collaborated with the European Union’s Bioprotect project. His team collected e-DNA samples along Iceland’s coastline, studied microplastics, and recorded environmental data that are valuable for marine conservation.
In this way, the journey became more than a test of human limits—it contributed meaningfully to scientific knowledge.
Interestingly, the idea for this audacious swim came from a conversation with actor Chris Hemsworth. Hemsworth suggested that swimming around Iceland would feel like circumnavigating Asgard, the world of the gods. He then followed Edgley’s expedition with great enthusiasm.
At the finish line, Edgley emphasized that the swim was not about speed or personal records. More than anything, he wanted to prove that with discipline, support, and courage, humans are capable of pushing beyond boundaries that once seemed impossible. (Wage Erlangga)
