10- 8 for swimming and two outside lanes to keep the backsplash down
The dimensions of an Olympic pool are required to be 25 meters by 50 meters. PCH=NOT 10
There are 10 lanes in an olympic swimming pool
FINA which is the world governing body for international swimming calls for a 50 Meter pool with 8 lanes. However movement is being created for having pools built with 10 lanes, with the outer 2 not being used for competition. (The waves created by swimmers bounces off the side walls and 'slows' down the swimmers in those lanes, thus an buffer is created by not using lanes 1 and 10 in competition). That said, if you are talking about size, Olympic generally refers to the length of the pool, not the number of lanes.
Typically 10 lanes.
The center lanes are assigned to the fastest swimmers.
when people swimming lanes divided by lane lines
to keep the swimmers in there own lanes
The width of a bowling center will depend on the number of lanes as a minimum width.
Swimming lanes are about 2.5m, or 8ft wide
