Tip 1: What is the longest Olympic swimming distance?

IOC classification
The International Olympic Committee (or IOC)divides the swimming distances into two varieties: in open and closed water, in other words, swimming in the sea or in the basin. Swimming in open water, or marathon distance, was included in the program of the competition recently, in 2008 in Beijing. Such a swim is carried out for 10 km. This is the longest distance in open water. Swimming in the pool is a more traditional discipline, and the longest distance in this area is 1500 m, freestyle.Russian-language official classification refers to swimming with water sports, the term "swimming" is not used.
Competitions in the pool
International competitions are held only inpools, the length of which is usually 50 or 100 m. Due to the fact that the athlete often changes direction, his speed of passing the same distance is often somewhat higher than if he swam along a longer stretch without making turns. There are several problems with fixing records on speed. In 1908 it was decided that records can be recorded only in longer basins than Olympic ones, so the records did not set records for swimming. But in 1956 this decision was revised, now records can be placed only in the pools of 50 and 55 meters long. Since 1957, the registration of records has been started again. In the period from 1988 to 1993, this decision was revised again, and now you can set records in the 25-meter pool.Swimming in open water

Once it was a lot of singles-experimenters, and now swimmers for long distances began to be mass-produced.The history of ultra-long swimming distances began in the 19th century, when British Briton Matthew Webb crossed the English Channel in 1975. To do this, it took 21 hours and 45 minutes.Open water competitions were included in thethe world championships in swimming in 1991. And now every even year, since 2000, the world championships in swimming in open water at a distance of 5, 10 and 25 km. But the longest Olympic distance on open water is still a 10 km swim.
