Endless pools are not a new concept, some of the major players have been going for over 25 years. However, the global pandemic has seen an explosion in the amount of attention that endless pools are getting and their sales. With the original Endless Pool model setting you back over $32,000 you may well question whether it is really worth buying one and if there is a cheaper option. So first thing first, is it worth it to buy an Endless Pool? If you are serious about your training, have the money and space to install one, then an endless pool is a great tool for improving your technique and will certainly make the training much more accessible in a convenient private setting.

An endless pool is a small swimming pool (around 15 feet by 8 feet) that uses a propulsion current that enables you to swim continuously. It can be used as a swimming training aid, allowing you to swim non-stop long distances without having to install a full-size swimming pool in your back garden.
There are a variety of different models offering different levels of intensity. The high-end Endless Pool Elite can pump out enough power to give a 51-seconds per 100-yard pace. As a comparison, the world record for 100 yards is 39.90 by Caleb Dressel in 2018 (source), so for the general swimming population, it is highly unlikely for the user to be swimming at the top speed of the Endless Pool Elite for any extended periods of time.
The Endless Pool Original model will give a top speed of 1:08 per 100 yards, which is plenty of pace for most triathletes.
The winner of the 2021 IRONMAN 70.3 in Dubai had a pace of around 1:04 per 100 yards (source), so if you can keep up with the pace that the Original model gives then you can consider yourself in great racing shape.
If you are looking for a more sedate swim then all of the models are adjustable, so you can have an easy 3:00 per 100-yard pace swim if that is what you are looking for.
There are a few different options when it comes to costs and you need to look at what you really need in terms of performance. There are also different sizes available and bear in mind that you need a little more space than the actual pool size so that you can access the inner workings for maintenance. The table below gives you an idea of the options available:
| Endless Pool | |||
| Model | Size | Price (USD) | Top Speed |
| Original | 15’x8’x42’’ | $32,199 | 1:08/100 yds |
| Performance | 15’x8’x42’’ | $34,199 | 1:04/100 yds |
| Elite | 15’x8’x42’’ | $39,099 | 51 secs/100 yds |
You can fully personalize the dimensions to suit the space you have available with any permutations of the following:
| Length | 12’ * | 13’ | 14’ | 15’ | 16’ |
| Width | 7’ * | 8’ | 9’ | 10 | |
| Depth | 42’’ | 48’’ | 54’’ |

If you are fortunate enough to be looking at buying an Endless Pool then you might want to know what the advantages are over a traditional pool, or open-water swimming. Let us take a look at the major benefits.
One of the biggest drawbacks of an endless pool is the initial capital that you need in order to purchase and install one.
Most of us do not have a spare $32,000 laying around, however, the companies have recognized this and Endless Pools offers a financial package that means you can pay off the cost of the pool starting at $950 per month (source).
Real-life race scenarios are something that you cannot replicate in an endless pool. You cannot practice your starts, be that water starts or land-based starts.
You will not get the practice of sighting that is imperative to racing. You also will not be able to get the hang of drafting other swimmers, which can save you up to 30% of your energy (source).
You will also have to keep an eye on the chemical balance used in the water or it may put the user of the pool at risk. For more on this check out our post What Happens If You Swim In A Shocked Pool? Precautions & How Long To Wait !
The two major players in the market are ‘Endless Pool’ and ‘Master Spas’ and both work on fundamentally the same principle of creating a current against which you swim.
Master Spas does have the accolade that their Signature Swim series was designed with help of legendary Michael Phelps, and you probably cannot argue with a 23-time gold medallist.
Here is a list of the main companies that you might want to take a look at in order to compare their products:

There are three main ways that you can use an endless pool to help your triathlon training and note that we do mean help. An endless pool is not something that you should look at to replace traditional training, particularly open-water swimming. You cannot replicate the choppy water, poor visibility, the need for regular sighting, fighting against tidal currents etc. Instead, it is a tool that can be used to supplement your training.
Take a look at the endless pool in action in the video below, and hear from Harvard University swim coach Tim Murphy about how he uses it in his training program:
All endurance training has an element of repetitiveness to it, so it is up to us to be creative in how we mix our training up. Cycling the same 10km route every session at the same pace, or running around a track every time you train for running will get tiresome pretty quickly.
The same goes for swimming, in an endless pool or a traditional pool, or open-water. If you look at the tips above on how you can add variety to your training then there is no reason why an endless pool should be boring.
However, one thing you can use to help with the boredom is a waterproof mp3. Check out our recommended battle-tested gear list
Endless pools have become increasingly popular for good reason. The added level of convenience along with the unique technical training that they can be used for means that this would be a great addition to your training tools if you can afford one.
