Bartłomiej Kubkowski (30, IISA bio here, @b.kubkowski, @wavemarketing.pro) from Giżycko, Poland was on his fourth attempt of a 170 km assisted crossing of the Baltic Sea as a charity swim for the Cancer Fighters Foundation (@fundacja_cancerfighters).
But he was pulled after swimming 159 km of the 170 km distance in his Ultra Baltic Swim 4.0 from Kåseberga, Sweden to Mrzeżyno, Poland.
His team posted the final update on August 20th at 7:51 am, “Unfortunately, after 55 hours of constant combat with the Baltic Sea, 11 km before the finish line, we had to stop and pull him from the water. He is in good condition and is currently undergoing checkups.”

His support team included mental coach Rafał Mazur, nutritionist Damian Wiatrowski, trainer Bartosz Paszkowski, physical therapist Andrzej Tryniszewski, and support crew members Przemysław Zawalich, Maksymilian Wysocki, Stanisław Klimaszewski, and Wojciech Rząsa.
Ultra Baltic Swim History
- In 2021, he swam 115 km from Kołobrzeg, Sweden en route to Ystad, Poland on his first 170 km Baltic Sea attempt, but his wetsuit and neoprene cap crossing was aborted after 32 hours 30 minutes.
- In 2022, he swam 116.897 km in his second attempt, using with a swim streamer while he raised 100,000 zloty for the Cancer Fighters Foundation, but his swim was aborted after 40 hours.
- In August 2023, he swam 130 km in 40 hours – despite snow falling during the mid-summer attempt – before he aborted the swim from Kåseberga, Sweden to Kołobrzeg, Poland, raising 300,000 zloty (€67,000) for the children’s cancer treatment.
- Today, he completed 159 km in 55 hours, a heroic effort with and against Mother Nature.
Kubkowski said after his 159 km battle in the Baltic Sea for the fourth time, “I am really tired. I think I need 2 or 3 days and I will be fine. In this year, we raised 231,863 Polish złoty (US$63,715) with the swim. After 4 years, we have raised 860,000 Polish złoty (US$236,326) for the children who are batteling with cancer.”
Those kinds of results are outstanding.
