Swimming is an event when you race in water. There are all kinds of events to swim. There is 200m breaststroke, 200m freestyle, 200m butterfly and 200m backstroke. There is also 400 meters of those events.
My favorite event is 200m and 400m medley. A medley is event in swimming when you change styles every time you touch the wall. But in 400m you have to touch the wall two times before you change styles.
There is also a team event in swimming. It’s a relay. You have to have five people form the same country to enter it.
