The phrase represents a specific type of open water swimming event, characterized by its location in a large body of deep, often oceanic, water. This contrasts with swimming events held in pools, lakes, or rivers. An example would be a long-distance race held offshore, testing the endurance and skill of participants in a challenging marine environment.
Such competitions offer several advantages. They provide a unique test of physical and mental fortitude due to unpredictable conditions like currents, waves, and temperature fluctuations. Historically, these events have grown in popularity, attracting both elite athletes seeking extreme challenges and recreational swimmers looking for a novel experience. Their growth reflects an increasing interest in outdoor activities and pushing personal boundaries.
