The 24-year-old ultramarathon swimmer cut short her attempt five kilometers from the finish on Tuesday due to extreme conditions.

“Yesterday, I began my attempt to swim the North Channel at 8 PM GMT, however I was unable to make landfall in Scotland. After 11 hours of swimming and 38 kilometers, 5 kilometers from the finish, the crew made the decision to stop in the interest of my well-being,” the Split native said, adding that as hard as that decision was to make, it was the right one.

“I am proud of myself. I swam for 11 hours in temperatures of 13, 14.5 degrees Celsius, choppy seas, against the current, and trying to avoid jellyfish. I gave it my all and I have no regrets. I thank everyone who supported me,” Levačić said, adding that she hoped she would come out of the experience stronger and more determined to achieve her dreams.

The finish was in Portpatrick, Scotland. Levačić has already competed four of the world’s seven most grueling ultra-swimming routes known as the Oceans Seven: La Manche, the Catalina Channel, the Molokai Channel and the Tsugaru Strait.
