On April 7, 2007 (February 20, 2007 in the lunar calendar), Martin Strell completed the feat of swimming the Amazon River alone in 65 days. On April 7, Slovenia Martin Strell celebrated next to a sign symbolizing the end of the journey in the Brazilian city of Belém at the mouth of the Amazon River. The Amazon River has always been known for its mystery and danger. How mysterious and dangerous is it? It is estimated that only 52-year-old Stree, a Slovenia native, has the most say in the world. Before setting off on February 1, 2007, Strey was well aware of how dangerous the Amazon River was. Parasite catfish could enter the body and cause disease, piranha could easily tear swimsuits, and bull sharks could take lives in an instant. Not to mention ferocious crocodiles and various pythons. He even had nightmares, but after waking up from the nightmare, Strey still set off from the source of the Amazon River in Peru without hesitation. Every day, Strey swam almost 80 kilometers. During the journey, in addition to the huge physical exertion, his swimsuit constantly scratched his skin. Cramp, dehydration, and vomiting were common. The scorching sun on the Amazon River sometimes made it difficult for him to bear. Of course, the biggest danger still came from the carnivorous piranhas and those blood-sucking creatures in the river. However, Strey said that he was lucky that he could always miss some big dangers every time, but these small dangers alone were enough for him to endure. By the time he was 100 kilometers away from the finish line on the 5th, Martin Strell's health deteriorated and he developed symptoms such as dizziness, diarrhea, high blood pressure, and trance. On April 7, the exhausted Strey still set one foot on the land of Belém, the Brazilian city at the mouth of the Amazon River, the world's second largest river, under the cheers of hundreds of people. The entire journey is 5265 kilometers, setting a world record for the longest distance swimming. "He reached the end of the river," Strell's son, Porut Strell, the event's coordinator, told The Associated Press."There was scheduled to be a celebration in Belen on the 8th, but he finished it today." His escort team, consisting of 20 people, escorted him in two canoes and a small boat and provided night accommodation. After landing, Strey was quickly taken to the hospital. News from the hospital said that Strey's health was not optimistic. In addition to heart disease, he also suffered from severe high blood pressure and other diseases. 52-year-old Martin Strey began to teach himself to swim at the age of 6. In 1997, he successfully crossed the English Channel. In 2000, he swam 3004 kilometers across the Danube River in 58 days, setting a world record for long-distance swimming. In 2002, he conquered the Mississippi River in the United States. In June 2004, Strey came to China and spent 50 days swimming the Yangtze River, the third longest river in the world. After conquering the Amazon River, the only challenge left for him is the Nile River. However, in his opinion, the Nile River is obviously not exciting enough, and the challenge coefficient is not much different from the creek.
