Triathlon swimming involves partaking in a multi-discipline race that includes swimming, cycling, and running. Participants swim a specific distance in open water, such as a lake or ocean, before transitioning to the next segments. Triathlon swimming demands both speed and stamina, as competitors aim to complete the swim section efficiently to excel in the overall race.

Open water swimming involves swimming in natural bodies of water, such as oceans, lakes, or rivers, rather than a swimming pool. Open water swimmers often participate in races or embark on long-distance swims, testing their skills and resilience in sometimes unpredictable conditions. This category allows swimmers to explore new environments and offers a sense of adventure, as they navigate various landscapes and water conditions.
