Well, this is beautiful. “Chasing the Sublime” is a short film from The Outdoor Swimming Society, directed by Amanda Bluglass, a group of adventurous, open water swimmers. The short features two of the founders of the group, Kate Rew and Kari Furre, preparing for a frigid swim somewhere in the UK. They stand at the water’s edge, dreading the cold, the discomfort, the fears of open water. But eagerly anticipating the immediate rush of feeling their most alive, they dive right in.
