What are Olympic pools, and why is a good Olympic Size important?

After watching Michael Phelp’s or Kate Ledecky’s multiple wins, you may begin to think Olympics pools are proximate to your normal pool. However, Olympic pools are different from regular swimming pools and are used for international competitions.

Usually, they attract international sportspersons and audiences. The race course length in these pools is 50 meters or 164 ft., commonly referred to as a long course.

Unlike the Olympic pool, other swimming pools are 25 meters long and accommodate a short course race. According to Fédération Internationale de Natation (FINA), if a competition decides to use touch panels, the pool must be 25 to 50 meters.

How to Choose the Right Olympic Pool Size

With a variety of pool sizes, you are perhaps wondering how you will ensure you meet all the Olympic swimming pools’ size measurements’ requirements. Below are some of the things you should consider before building a pool for your institution or training sessions;

1. FINA Requirements

The International Olympic Committee recognizes FINA for the international administration of water sports. Hence, it follows all the FINA measurement requirements when building all its swimming pools for water games.

So, suppose you want to build a similar size pool for a water polo or swimming competition, you will need to adhere to all the different dimensions. FINA demands the pool construction to have 50 meters in length, 25 meters in width, and 2 meters in depth.

Whether you are building outdoor or indoor pools, you should ensure enough space between the walls and the first or last lanes. And if you decide to include touch pads, add between 0.01 to 0.02 meters to accommodate them.

2. Purpose

What’s the purpose of your Olympic-sized swimming pool? Whether you are building competitive swimming pools or recreational pools, you have to ensure they serve the purpose exceptionally.

For instance, if the pool construction is aimed at helping swimming athletes train for competitions, the pool should have the necessary equipment, including touch pads, similar pool temperatures, and lane-wall distance, to avoid the water ripple effect on the swimmer.

3. Race Course

The type of race course the swimming athletes will be competing in determines the minimum distance of your pool. Hence, you must create 25 yards for the short race and 50 yards for long-distance races.

Don’t forget to have a 90-degree angle between the pool walls and the swimming lanes. FINA allows an allowance of ± 0.3 degrees regardless of the type of pool course.

4. Affordability and Return

Whether you want to build a 25 or 50 yards pool, you must evaluate if it matches your budget requirements. Reason? If the pool is above what you can afford, you may have to delay the pool construction due to inadequate funds, wasting time.

Once you build the pool, you need to estimate its’ returns to your company or institution. This will help you make profitable decisions like building a 25 yards pool instead of a 50-yard pool if the demand for swimming is not as high in your residence.

5. Additional Costs

Besides paying the initial capital for construction, you will need to hire a professional for the pool maintenance activities. Other people prefer having heated pools which can be pricy in the long run, especially if they carry a lot of water.

So, when choosing between a 25 or 50-yard Olympic competition pool, ensure you can afford to pay for the additional or recurring costs. This will ensure you operate efficiently and get maximum benefits from the pool.
