Greek ultra-distance swimmer, Spyros Chrysikopoulos, has once again etched his name in the record books, conquering his second Guinness World Record for Greece. This extraordinary feat, titled “The longest swimming distance in 48 hours in a 50m pool,” saw Chrysikopoulos push the absolute boundaries of human endurance.
The monumental effort began on Friday, July 18th, at 12:00 PM and concluded precisely 48 hours later, on Sunday, July 20th, at 12:00 PM, within the 50-meter indoor pool of OAKA. Despite being sleepless for the entire duration, Spyros swam an astonishing 151 kilometers.
Guinness World Records had set the formidable target of 150 km. In a testament to his unwavering determination, Spyros not only met but surpassed this mark a full half-hour before the deadline (at 11:30 AM on Sunday), even managing to complete an additional kilometer for good measure.

This latest triumph marks Chrysikopoulos’s second Guinness World Record. His first, achieved in 2021, garnered international acclaim when he swam an incredible 358.2 km in 7 days. Yet, in his own words, this 48-hour challenge was “more difficult and more demanding” than his previous 7-day record.
Greek Ultra-distance swimmer battled severe pain
More than just a physical challenge, this endeavor was a profound battle of will. Spyros battled severe pain as his body was pushed to its absolute limits, but the sheer strength of his mind propelled him forward, preventing him from succumbing. He unequivocally proved, once again, that human limitations are truly made to be overcome.

The relentless nature of ultra-distance swimming, especially multi-day events, means fighting overwhelming urges to sleep, leading to cognitive impairment and increased sensitivity to pain. Hours of repetitive motion in a pool or endless stretches of open water can lead to intense boredom, making the passage of time agonizingly slow. Athletes like Chrysikopoulos suffer from shoulder pain which is far the most common and debilitating injury caused by the repetitive motion of hundreds of thousands of strokes.
However, his remarkable achievement stands as powerful evidence not only of exceptional physical endurance but also of the indomitable spirit of the human soul in the face of pain and doubt. Carried out with meticulous adherence to Guinness World Records specifications in the OAKA’s 50m indoor pool, just as in 2021, this new record solidifies Spyros Chrysikopoulos’s status as one of the world’s most significant endurance athletes.
His incredible journey continues with the support of dedicated sponsors: CUPRA, Motor Oil, THEONI Natural Mineral Water, MINNETA Insurance, NGR, Hippocrates General Clinic, MITSIS Group, Athens Orthopedic Center, and Oneiro Cruises.
