Swimrun is a rapidly growing endurance sport that blends open-water swimming and trail running into a continuous, dynamic race format. Unlike traditional triathlons, athletes transition multiple times between swimming and running, often across rugged terrain and open water, while wearing the same gear throughout the event. Originating in Scandinavia, the sport has evolved into a global phenomenon, attracting athletes who crave both physical challenge and adventure in natural environments. With courses designed to test endurance, adaptability, and teamwork, Swimrun demands a unique balance of fitness, mental toughness, and strategic preparation — making it one of the most exciting endurance disciplines to emerge in recent years.
