Olympic-size swimming pool Olympic-size swimming pool An Olympic-size swimming pool conforms to regulated dimensions, large enough for international competition. This type of swimming pool is used in the Olympic Games, where the race course is in length, typically referred to as "long course", distinguishing it from "short course" which applies to competitions in pools that are in length. 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. An Olympic-size swimming pool is
Swimming pool by the pool, the cover eliminates heat loss due to evaporation and reduces heat loss at night through its insulating properties. Most swimming pool heat loss is through evaporation. The heating effectiveness of a cover depends on type. A transparent bubble cover is the most effective, as it allows the largest amount of solar flux into the pool itself. Thermal bubble covers are lightweight UV-stabilized floating covers designed to minimize heat loss on heated swimming pools. Typically they are only fitted in spring and fall (autumn) when the temperature difference between pool water and air temperature is greatest. They raise
