Mark Sowerby’s life was upended in 2018 when a highly publicised short-selling attack on Blue Sky dismantled his reputation, identity, and self-belief. Turning to the ocean not for glory but for survival. Mark utilises marathon swimming as a mechanism to master fear and navigate the paralysis of prolonged uncertainty. Over the course of a decade, he attempts the Oceans Seven, a gruelling odyssey through cold, darkness, and apex predators. By his final crossing, Mark’s journey transcends mere physical endurance, evolving into a profound reclamation of self, achieved only by surrendering control to a team he learns to trust implicitly.
