That Olympic Pool is Really Big. Like, Really, Really Big
Indeed, the pool is large. The first Olympic swimming competitions of the "modern" Games took place in the sea or in a river, which, traditionally, are good-sized bodies of water. Competitions now take place in a 50-meter swimming pool, which is usually indoors.
If someone -- like your boastful brother-in-law or the neighbor who fancies himself the Mr. Jones everyone with whom everyone is trying to keep up -- tells you they have an Olympic-size pool in their backyard, this person is either:
- Wealthy
- Owns an estate or lots of land
- Resides in an institution, like a school or some sort of municipal building
- Misguided
- An outright liar
A regulation Olympic competition pool:
- Contains about 500,000 gallons of water
- Is 50 meters long
- Width: 25.0 meters
- Depth: 2 meters (minimum); 3 meters recommended
- Pools for Olympic Games and World Championships must be equipped with flush walls at both ends*
- Number of lanes: 8 (eight), for World Championships and Olympic Games: 10 (ten). Five feet deep
