Endurance swimming is a form of long-distance swimming that focuses on maintaining a steady pace over extended periods. It is often practiced in open water, such as lakes, rivers, or oceans, and can involve distances ranging from a mile to several miles. Swimmers develop their stamina and technique to efficiently cover these distances while managing their energy levels. Training for endurance swimming typically includes a mix of distance swims, interval training, and strength exercises. Swimmers often participate in events like marathon swimming or triathlons, which test their ability to swim long distances in various conditions. Proper nutrition and hydration are also crucial for optimal performance.
