After swimming from Stockholm to Helsinki—a record-setting 500-kilometer unsupported swim—Swedish adventurer Jari Cennat Tammi is well on his way to completing his next big challenge. In October 2024, Tammi began his attempt at “the world’s longest swim adventure” a 10,000-kilometer effort from Istanbul, Turkey to Cadiz, Spain that will take him along the edge of the Mediterranean Sea.
The challenge will take the 66-year-old years to complete. As during his Stockholm to Helsinki swim, which took him 52 days, Tammi is towing his food and gear behind him as he swims. As of the time of publishing, Tammi’s challenge has been live for 208 days. He’s currently working his way along the coast of Turkey, sharing an update and photos on his tracker every day. He’s catalogued it all—from the start of the adventure last fall, the amount of sleep his getting and the people he’s met, to experiencing his first earthquake this week.
And even though Tammi is taking on a new type of challenge with this adventure, he writes on his tracker—which also serves as a quasi-blog, that it’s not a race against the clock. On April 25, Tammi wrote “I made a good course in the Marlin App, so I didn’t have to swim so much in shallow water. My plan was to swim 5,800, but when I saw this place it looked so beautiful so I wanted to stay here. Just have to remind myself that this is not the race this is a way to live.”
In addition to keeping up to date with Tammi’s adventure with his tracker, you can find out more about what he’s brought with him for this expedition below in a video he made before launch with Subtech, the makers of the pack he tows with him in the water.
