Ultra-athlete and shark advocate Ross Edgley goes head-to-head against four of the oceanâs most formidable sharks. Heâs won the world record for the worldâs 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 â the worldâs fastest shark â and finally, he tries to feast like a tiger shark.
