Ultra-athlete and shark advocate Ross Edgley goes head-to-head against four of the ocean’s most formidable sharks. He’s won the world record for the world’s longest assisted stage sea swim of nearly 1,800 miles but now Ross is pushing himself even further and testing his speed, strength, endurance, and digestive system. In four jaw-dropping shark challenges, Ross attempts a G-force turn like a hammerhead, a polaris jump out the water like a white shark, to out swim the mako — the world’s fastest shark — and finally, he tries to feast like a tiger shark.
