In what can only be described as a jaw-dropping feat of endurance, marathon swimmer Andy Donaldson has set his sights on a new Guinness World Record—after sharing the water with 5,500 crocodiles. The Scottish-Australian athlete completed a 34-mile swim up the Ord River in Australia, a stretch of water famously teeming with the formidable reptiles. The journey took him roughly 16 hours, and for the final leg, he was joined by a group of local swimmers eager to share in the moment.

"I would never say I'm not scared going into something like this," Donaldson admitted, reflecting on the mental preparation required for such a daring challenge. Despite the obvious risks, he pushed through, driven by a deeper purpose. The idea for the record came after a local swim coach invited him to the town of Kununurra, where Donaldson felt inspired to motivate younger athletes. "One of those messages I think I'd love to get out to people is that no dream is ever too big," he said.

Already holding three Guinness World Records, Donaldson is no stranger to pushing boundaries. After the swim, he admitted to experiencing cramps "pretty much everywhere," but that didn't stop him from celebrating with the crowd. He was all smiles, handing out high-fives to locals who came out to watch and even join him in the water. The feat has captured global attention, and ABC News has reached out to Guinness World Records for official confirmation. For anyone who's ever doubted the power of determination, Donaldson's swim alongside 5,500 crocodiles is a powerful reminder that no goal is out of reach—especially when you're willing to dive right in.
