Olympic-size swimming pool
An Olympic-size swimming pool is the type of swimming pool used in the Olympic Games, where the race course is 50 metres in length. This is typically referred to as "long course", delineating it from "short course" which applies to competitions in pools that are 25 metres in length (typically, width of 50 metre pool). If touch panels are used in competition, then the distance between touch panels should be either 25 or 50 metres to qualify for FINA recognition. This means that Olympic pools are generally oversized, to accommodate touch panels used in competition.
|Length||50 m (164 ft)|
|Width||25 m (82 ft)|
|Depth||FR 2 Swimming Pools:
minimum 1.35 m (4 ft 5 in) between 1 m and 6 m from ends;
|Number of lanes||10|
|Lane width||2.5 m (8 ft 2 in)|
|Water temperature||25–28 °C (77–82 °F)|
|Light intensity||minimum 1500 lux (140 footcandles)|
|Volume||Based on a nominal depth of 2 m, this is 2,500,000 L (550,000 imp gal; 660,000 US gal)
or, in terms of cubic volume, 2,500 m3 (88,000 cu ft), as is commonly quoted.
There must be two spaces 2.5 m (8 ft 2 in) wide outside lanes 1 and 8 (in effect, two empty lanes). The length of 50 metres (164 ft) must be between the touch pads at the end of each lane, if they are used. If starting blocks are used, then there must be a minimum depth of 1.35 metres from between 1.0 metres from the end of the pool to at least 6.0 metres from the end of the pool. At all other points, the minimum depth is 1.0 metres. If the pool is used for Olympic Games or World Championships, then the minimum depth is increased to 2.0 metres.
At FINA's 2009 Congress, rules were approved for 10-lane courses for competition, as an alternative to the more traditional 8-lane course.
