Swim analysis in the endless pool

Swim analysis endless pool

Last week Gosse visited Tri-PT Studio for his first swim analysis in the endless pool. In this blog you can see and read Gosse’s experiences. This way triathletes and swimmers with an interest in a swim analysis in our endless pool get a good idea of how a swim analysis works.

An earlier article describes the entire process of a swim analysis step by step.

Last summer I participated for the first time in a sprint triathlon and I really enjoyed it. Now I am training for an Olympic triathlon. Cycling and running training go well for me, but I still see swimming as an obstacle. That is why I opted for an indoor swim training / analysis.

At first it took some time getting used to swimming in the endless pool, but after a few strokes it already felt quite natural. I first swam a bit as I would do during a triathlon so my movements could be properly analysed. After this I was allowed to watch the screen as I swam and I received clear feedback and tips from Paul.

The tips and feedback were then incorporated into a few exercises and these were also analysed. This analysis clearly showed that I was swimming much more stable and controlled. This is exactly what I was looking for. I have been given the exercises and analysis images and I can start working on this myself. I plan to come back in a few months before my competition to see if the exercises have helped and to update my technique for the specific competition.

Swimming analysis in the endless pool: step-by-step

endless pool huren

The endless pool is part of Tri-PT Studio for a few months now, dozens of swimmers have been able to improve their technique during this time. Right now, when it’s not exactly swimming weather, it can be useful to improve your technique. This way you have an advantage over the other swimmers and triathletes when the season starts again. But how does that work, an endless pool? This article describes step by step what a swim analysis looks like in practice.

1. Contact Tri-PT Studio for an appointment

Step 1 is to make an appointment at Tri-PT Studio. This is easily done via telephone, WhatsApp or e-mail. It is also possible to make the appointment physically when the studio is visited, so you immediately get a picture of our endless pool.

1.1 What does it cost for a swim analysis in the endless pool?

The rates for a swim analysis in our endless pool are described below. There are two options for doing a swim analysis at Tri-PT Studio.

Swim analysis (45 min.)€ 85,incl. video images and analysis
6 x 45 min. 1 on 1 training€ 405,-incl. 2x video images and analysis

Usually, swimmers are able to schedule an analysis within 7 days from the first contact moment. Contact us now to check availability!

2. Preparation for the swim analysis

The appointment has been made, now the preparation for the swim analysis can begin! For many athletes it is reassuring to know that they do not need to prepare physically. We get the best result of the analysis when a swimmer swims “normally”. That is why you can achieve the most results.

In terms of supplies can be prepared. For example, it is useful to take the following:

  • Swimwear
  • Towel
  • Bathrobe
  • Diving mask
  • Snorkel
  • Nose clip

Some of these attributes (snorkel, diving mask, nose clip, zoomers) are also present in the studio, which can be used by swimmers.

2.1 How hot is the water in the endless pool?

This is a question that we get a lot from swimmers. The water of the endless pool is 25 degrees, about 2 degrees lower than a “normal” pool.

3. The swim analysis

On the day of the swim analysis itself it is wise to be around 15-20 minutes in advance. Then the trainer can get acquainted and expectations or goals can be discussed. In total, the swim analysis and everything around it takes around 75 – 90 minutes.

The swimming video of is viewed during the analysis. On the basis of these images, it is discussed how swimming technique can be improved. This advice can be applied directly by the swimmer, because of the mirrors in the endless pool, the swimmer also has “direct” feedback.

4. After the analysis

After the training there is time for a cup of coffee with the trainer, so that you can discuss the results again. Here swimmers also receive tailor-made advice, allowing them to improve their swimming technique.

The detailed analysis is sent within four working days. The analysis consists of “photos” obtained from the video analysis, supplemented with tips and processed in a document.

5. Back in the water!

Time to put the advice and tips of the Tri-PT Studio specialist into practice. Now the swimmer can work on the swimming technique. If there is a need for another analysis, it is recommended to schedule this 4 to 6 weeks after the first analysis. This time depends on the frequency with which someone is swimming and the level, for a novice swimmer it may be good to do the following analysis after 2 to 3 weeks. The Tri-PT Studio trainer provides advice on this.

Triathlon training in offseason


The last few months have been the most important months of the year for most triathletes. Training all year for that one race or a few ones in the summer. It is very important not to stop training or to loose grip in the winter. And this is slightly more difficult for triathletes, than it is for athletes who “only” practice one sport.

In addition, the winter weather is not particular motivating neither. Earlier I wrote an article with tips for triathlon training in offseason, this article is specifically about keeping track and improving cycling and swimming condition and technique in offseason.

Offseason training in the endless pool

Tri-PT Studio proudly presents our endless pool. We opened in October 2019 and our endless pool was also opened. This pool makes it possible to swim endlessly throughout the year. The dimensions of this bath are approximately 520 cm by 240 cm.

One of the big advantages of the endless pool is that there are no turning points while swimming. This allows the swimming technique to be analysed very closely and thereby also be improved. In general, swimming training in an endless pool is around 20% to 30% more effective than in a regular swimming pool.

How does the endless pool work?

At the “front” of the pool is a motor that ensures that there is a current in the endless pool. The speed and power of this current can be adjusted completely as desired. This ensures that both experienced swimmers and beginners benefit from using an endless pool during the training sessions.

The current is wider than the width of the swimmer and deeper than dept of the swimmer itself. The water reaches the back of the pool through and along the swimmer. The water is then pushed back from both sides to the “front” of the swimming pool, where it is pushed back towards the swimmer. This circulation ensures as little turbulence as possible, while making optimum use of the power of the endless pool.

Training in the endless pool

Curious about how you will enjoy swimming in an endless pool? During a training in the endless pool of Tri-PT Studio you will be guided by highly qualified trainers. In addition to coaching during and after swimming, you will also receive video footage of the session and a detailed analysis. This allows you to get started yourself after training in the endless pool.

Tri-PT Studio is easy to reach and accessible to athletes of every level. In front of the door there is the possibility to park for free. The studio is also easily accessible by public transport. We are located next to the Voorschoten station, where trains and buses stop.

Cycling in off season

It is fairly obvious that swimming in the fall and in the winter is not as easy as in the summer. Running and cycling can also be done indoors in almost every studio. What makes Tri-PT Studio so interesting for triathletes is the presence of the Wattbikes. These bikes are used to guide and support athletes through WattCycling. Below you can read more about why WattCycling is a solution for athletes who not only want to stay fit in the winter but also want to improve their level.

What is WattCycling?

The Wattbike is used for WattCycling. This is the most advanced indoor bike that exists. Athletes who use the Wattbike describe this as a real cycling experience. The unique thing about this indoor bike is that your performance is accurately measured and you receive continuous feedback from the Wattbike.

You don’t use WattCycling just to stay fit in the winter. It is precisely a method to take your cycling technique to the next level. For example, think about improving your kicking technique so that you can put more power. In addition to strength, efficiency is also central to the training.

WattCycling at Tri-PT Studio

It is possible to only train on the Wattbike or to do this as a group. The training sessions last around 80 minutes. Athletes can choose between a Tri / Endurance training that focuses on long bike rides and time trials, d ‘Huez for a combination of longer intervals and a low pedaling frequency with high resistance or High Intensity Training with many intervals and high intensity.

Each of these courses is specially designed to make a specific goal feasible. For those who do not have a specific goal in mind, there is a fourth option, a combination of all three courses.

There are various options with regard to subscription or ride card for WattCycling. Read more about WattCycling or contact Tri-PT Studio directly.

Things to keep in mind when purchasing a triathlon bike

Triatlon fiets kopen

In one of my earlier blogs I gave the tip not to immediately purchase an (expensive) triathlon bike as a starting triathlete. However, if you do intend to purchase a triathlon bike, here are some points to take into account.

The importance of the correct cycling position during a triathlon

The correct position while cycling is a crucial thing. Because of the fact that a triathlon consists of multiple disciplines; swimming, cycling, and running, you don’t want to waste any energy due to an incorrect cycling position. In addition, an incorrect position can also cause injuries. For these reasons, I definitely recommend you to have a bike fit (bicycle measurement) done before the purchase of a triathlon bike. Moreover, I also recommend this if you already have a bike, but haven’t done a proper bike fit for your bike yet. A correct cycling position is essential and you can gain a lot from this for your triathlon.

A racing bike or a triathlon bike?

You could say that the type of bike depends on the triathlon distances that you want to complete. The shorter distances, respectively, such as a sprint or Olympic distance mainly require aerodynamic bicycles. For longer distances, such as half a triathlon or the Ironman, comfort (the right cycling position!), nutrition and hydration are also very important. Space for at least 1 bottle is required. So, for these distances, it is important to have a bike that also abides to these requirements. I can say that for the longer distances it’s certainly advisable to ride on a triathlon bike.

For the shorter distances, a normal racing bike could stand up perfectly for the task. You might even add a triathlon steering wheel for more aerodynamics. For these reasons, it isn’t really necessary to immediately purchase an expensive triathlon bike as a starting triathlete!

The difference between the triathlon bike (time trial bike) and the racing bike

The difference between the two types of bicycles can be found in the geometry of the bicycles and the bicycle position when riding the bike. Because, in addition to the cycling part, a triathlon also consists of a swimming and a running part, which means that the upper body is already tired before you start cycling. Thereby, you must also have enough energy left in your legs for the running part.

This means that the geometry of a triathlon bicycle also ensures that the bicycle movement matches more closely to the subsequent running movement, making the transition between cycling and running more easier which results in spilling less energy.

Buying a new or second-hand triathlon bike?

It isn’t really necessary to buy a brand new triathlon bike as a starting triathlete. The purchase of a second-hand racing or triathlon bike will definitely be a good option for starting triathletes. However, it is very important to pay attention to the correct cycling position. Especially with a second-hand bike. The body position will be different for everyone, depending on someone’s posture. So, if you are already familiar with a certain brand and its bike fit, I advise you to stay with that brand.

The right bike fit is a must

In the end, the choice for a racing or triathlon bike, new or second-hand, mainly depends on the distances you want to cycle and your available budget, of course. As a triathlete with the aim of cycling the shorter distances, a (second-hand) racing bike will suffice. If your goal will be a half or a whole triathlon, I would recommend you to go for a triathlon bike. Regardless of your goal and the type of bike you decide to purchase, the right bike fit is essential. This is something you should really keep in mind when purchasing your triathlon bike.

What are the benefits of a triathlon watch?

Triatlon horloge

Thanks to technologies such as GPS and the advanced possibilities to measure speed and distances, a triathlon watch can be very useful for every triathlete. In this blog I give a brief explanation of the different functions of a triathlon watch and I explain a number of watch brands.

The difference between a triathlon watch and a regular sports watch

Whereas sports watches were previously only able to display time and heart rate, the functions of these watches are now much more extensive. Especially due to the built-in GPS and the advanced tracking functions that can be found in many triathlon watches. You could see it as a smart watch specially designed for the multisport triathlon. These watches are therefore perfectly capable of registering the multiple disciplines, which is the difference with a normal sports watch. I certainly dare to say that a triathlon watch contributes to a more effective training for your triathlon.

The different functions of a triathlon watch

Just as a triathlon consists of three different disciplines, a triathlon watch also works in three different modes. Namely swimming, cycling and running. To be able to train effectively, it is important to be able to follow all those three components carefully. Of course, you want to know as precisely as possible what your average speed is for each different part. Thereby, it is also important to know how much rest you should have in between your training sessions. Many triathletes underestimate the importance of rest. So, a triathlon watch that can remind you of this is very useful. Thanks to the connection that is possible between a triathlon watch and the various training apps, it is very easy to accurately track all your training results.

The different brands and types of triathlon watches

There are different types and brands of triathlon watches on the market. The price of a watch depends on the different functions. Starting from around € 250,- for a good triathlon watch. However, you can make it as pricey as you would like. I’m a fan of the watch brand Garmin myself, but the watch brand Polar is also known for their triathlon watches of good quality. There are of course several more brands on the market, but for now I will stick to the watch brands I just mentioned.


Garmin Forerunner 935

One of the latest models from Garmin is the Garmin Forerunner 935. This is a very advanced triathlon watch that has many different functions. This watch is able to keep track of the average heart rate and speed and the Garmin 935 can also make a prediction of your end time. In addition, this watch also has a length tracker and a SWOLF tracker. These functions enable you to accurately measure the length and number of swimming strokes. This makes this triathlon watch an excellent tool to improve your swimming technique. This Garmin triathlon watch also feels great on the wrist because of the narrow design and light weight of the watch. When using GPS, the battery can last up to more than 10 hours. A very suitable watch for the fanatic triathlete and the long distances. However, all the advanced functions of the Garmin Forerunner 935 do have a price tag. This triathlon watch costs around € 450,-.

Garmin Forerunner 735XT

A cheaper alternative to the Garmin 935 is the Garmin Forerunner 735XT. This model is available for less than € 300 and has about the same functions as the Garmin 935. The difference is mainly found in the shorter battery life (on average 8 hours with intensive training and use of GPS) and the lack of possibility to connect with WiFi. For triathletes with a less higher budget, this triathlon watch is a good option.

Polar Vantage V and Polar Vantage M

The both Vantage models from the watch brand Polar have a lot in common. In fact, the Polar Vantage V can be seen as a more extensive version of the Polar Vantage M. In addition to registering the average speeds on the various components, like this is the case with the other watch brands, the Polar Vantage V can also register your running power. Thanks to a built-in barometer, the power of your running steps can be measured while running. The Vantage V also has a so-called “Recovery Pro function”. This function indicates whether you have taken sufficient rest time in between your training sessions or not. Due to the more extensive functions of the Vantage V, it also costs a little bit more in contrast to the Vantage M model. For example, the Polar Vantage V costs around € 450,- and the Polar Vantage M costs around € 250,-.

Which triathlon watch for a starting triathlete?

As a starting triathlete, it is understandable not to immediately opt for the most expensive model. The Polar Vantage M and the Garmin Forerunner 735XT are both triathlon watches that offer all the necessary functions for a reasonable price. Therefore, these watch models are the triathlon watches that I would recommend for a starting triathlete.

Which triathlon watch is my favorite?

My personal preference goes to the watch brand Garmin. The newest model (the Garmin Forerunner 935) is currently my favorite. This due to the many advanced functions, the fine fit and the watch design itself.

Triathlon – what are the different distances?

Triatlon distances

In one of my earlier blogs I wrote about the origin of the distances of the “original” triathlon from the first triathlon competition in Hawaii. These distances are 2.4 miles for the swimming portion, 112 miles for the bicycle portion and 26.2 miles for the running portion. These are also the distances of the entire triathlon, also known as the Ironman. In addition to the distances of the Ironman, triathlon also has several shorter distances as well. In this blog I will give an explanation of the different distances in triathlon.

The table below shows the most common triathlon distances and the lengths of the different disciples.

[table “4” not found /]

Olympic triathlon / standard triathlon / quarter triathlon

Triathlon has been an Olympic sport since 2000. The Olympic distances of a triathlon are different from the distances of the original triathlon. Namely 0.93 miles of swimming, 24.8 miles of cycling and 6.2 miles for running. Today these distances are also referred as the “standard” distance by the International Triathlon Union (ITU). The reason for this is the fact that the Olympic name is a protected brand name of the Olympic Committee. In fact, the Olympic distance is actually a quarter of a triathlon, but then with 0.93 miles for the swimming portion instead of 0.62 miles.

Half triathlon / half Ironman or Ironman 70.3

When you talk about half a triathlon you automatically think of the same distances as half an Ironman. Namely 1.2 miles of swimming, 56 miles of cycling and 13.1 miles of running. Yet the distances between the half triathlon and the half Ironman are different. The distances of half a triathlon are 1.55 miles of swimming, 49.7 miles of cycling and 12.43 miles of running. The distances of the half triathlon are also seen as the “middle” distance. The half Ironman is also called the Ironman 70.3. The number 70.3 stands for the total mileage of the race.

Sprint distance / eighth triathlon / super sprint

The shortest distances in the triathlon sport take place in the sprint distance, the eighth triathlon and the super sprint. The distances of the sprint distance are 0.5 miles of swimming, 12.4 miles of cycling and 3.1 miles of running. The distances of the eighth triathlon are 500 meters miles of swimming, 12.42 miles of cycling and 3.1 miles of running. The distances of the half sprint are 375 meters of swimming, 6.2 of cycling and 1.55 miles of running. So this is exactly the distance of a whole sprint.

Mini triathlon

In addition to all the above distances, there are also the “mini” triathlon distances. These distances usually have two variants: 100 meters of swimming, 5 km of cycling and 1.25 km of running or 250 meters of swimming, 10 km of cycling and 2.5 km of running. The first variant of the mini triathlon is intended for children from 8 years. The second variant of the mini triathlon is intended for children from 10 years.

What is drafting and in which distances in triathlon is this allowed or not?

Drafting can be explained as cycling close to your predecessor. You often see this in cycling races. In triathlon sports it depends on the distance of the race whether drafting is allowed or not. For example, drafting is allowed at the Olympic Games and therefore at the Olympic distance. Drafting is not permitted in the other triathlon distances. Thus, all the distances longer than the Olympic distance. This means that you have to keep a distance of at least 12 meters away from your predecessor. In this case, overtaking maneuvers must be carried out quickly and neatly. According to this, you could say that drafting is allowed in all the shorter race distances than the Olympic distance. However, in practice there are also short races in which drafting is not allowed. Thus, if you participate in a triathlon shorter than the Olympic distance it is always advisable to check whether drafting is allowed or not.

Why is the order of a triathlon 1. Swimming, 2. Cycling and 3. Walking?

This has to do with safety and the fatigue of a triathlete during and after each portion . Swimming is the first part in triathlon. If the cycling or running portion would be first during a triathlon, this will mean that you have to go swimming with tired legs. This can cause cramping and is therefore dangerous for a triathlete. For the same reason cycling is the second part in triathlon. If you first go running and then have to cycle with tired legs, you could fall because of the tiredness. Therefore, running is the last portion in triathlon. If you get exhausted while running you always have the option to go further on a walking pace. Thereby, falling of a bicycle will be much more dangerous than falling while running.

Triathlon distances for men and women

The competition distances in triathlon sport are the same for both men and women. There is no distinction made here. The competition forms in triathlon sport consist of separate competition forms for men and women as a mixed competition for both men and women as well.

Offseason triathlon training tips

Offseason triathlon training tips

The offseason is a hard time for triathletes. We have to find a balance in between giving our bodies the rest they deserve and staying fit enough for the first races of this year. This seems like a hard balance, given the nature of these two concepts.

Staying fit in the offseason or winter is different than working out in the rest of the year is. The roads may be snowy, the weather may be cold and wet. These are not exactly the weather conditions that you want to when running, cycling or open water swimming. I wrote down ten offseason triathlon training tips to help you through this offseason.

1. Implement strength training for triathlon, not body building

One of the most common ways to improve in the offseason, in my opinion, is strength training. Try focusing on multiple-muscle movements that complement triathlon sports movements when working out with weights. This helps you to perform better and decreases the risk of injuries.


2. Intergrade fast workouts in your weekly workout routine

Training in the offseason can seem as if it’s the same all over, all the time. One way of making offseason triathlon training more diverse is intergrading fast workouts in your weekly routine.


If you work out three times a week or seven times, it is always wise to increase the speed of some of these workouts. Doing so helps your body to make gains by experiencing the stress of fast workouts.


Offseason triathlon training tips


3. Plan 2 to 4 key workouts per week, focusing on improving speed, endurance or both

These harder key workouts help effectively to reach your offseason goals. Whether your goal is to improve endurance, speed or both, key workouts will help you reach this goal. Try to limit the frequency of these workouts to two to four times a week.


4. Focus on your ‘weak’sport during the offseason

If you are having a harder time swimming than you do running or biking it is, of course, wise to focus on swimming during the offseason. This seems obvious but keep in mind that adding one extra session per week is not going to help you enough. Try implementing four or five sessions per week. Be careful with running and cycling since with these sports it is easier to get injured.


5. Use the professional advice of a triathlon coach to finetune your swimming, running and cycling techniques

A small improvement in your technique can lead to great results! If you do not wish to work with a professional triathlon coach you could also ask an experienced triathlete to take a look at your techniques during the offseason.


Offseason triathlon training tips


6. While swimming in offseason, set daily and weekly goals

Swimming without a purpose is neither fun nor motivating. Start beating PR’s on a weekly basis to increase your motivation!


7. The offseason time is a perfect time to try other sports

Alternative sports can be used to prevent mental fatigue. Swimming, running and bicycling are great but giving other sports a try can have positive results as well. How about mountain biking for more bike-handling skills, or indoor climbing to strengthen your core, back, arms and shoulders.


8. Use the time off in the offseason to give your running legs the rest they deserve

Running is rough on the body. An average runner has at least one injury per year. Use the time off from the offseason to help those legs recover from last years races. Instead of running, you could train with light weights and cords to simulate running movement or try aqua jogging, since you’re going to be in the pool a lot anyway.


9. Take that break and reflect over last year’s results

We, athletes, are people of habits. We like to stay busy training for upcoming races and improving techniques. The offseason is the perfect occasion to really take a break from training, both physically and mentally.


Offseason triathlon training tips


10. This is the perfect time to experiment with new equipment

Now is the time to upgrade your gear. If you feel like upgrading wetsuits, wheels, running shoes, helmets, nutrition or an entirely new bike, do it now. You don’t want to mess around with untested equipment when the race starts.


The offseason makes us appriciate the raceseason even more. Let’s try to appriciate the offseason as well. Use these 10 offseason triathlon training tips to achieve better results on your next race!

For a number of years training weeks have been organized at Le Petit Mas d’ile, mainly focussing on triathlon.
Le Petit Mas d’ile is located in the Charente in France, less than 900 km from Utrecht.

The first weeks that were organized were under the inspiring leadership of Frank Heldoorn, but unfortunately it had to pass the baton after 3 years due to circumstances. That baton was accepted in gratitude by the owner of Le Petit Mas d’Ile himself together with Karin Sloove, a multi-sports athlete who has followed various training courses. From mountain biking to triathlon trainer.

In the meantime two trainers have been added, Marjan van Galen and Rob Kwaaitaal. The latter will take the lead for the swimming week to be organized. Indeed, also a training week with an emphasis on swimming. Marjan will help with the 4th triathlon week in June.

From all this, the need arose to create an all-encompassing website for the various sport weeks. Because even if you only want to cycle for a week you could also go to Le Petit Mas d’Ile. We are happy to welcome you.

How to choose a tri suit?


Wearing a tri suit is strongly recommended for anyone who wants to participate in a triathlon, young or old, beginner or expert. The tri suit is, the name says it all, made for all three parts of a triathlon. This makes that the triathlon can be covered without blisters and as streamlined as possible. In addition to a special thin pad for running and swimming, most tri suits also have a storage space. Here you can put nutrition and (sports) drinks so that you can get the best out of yourself while staying hydrated and well fed.

In addition, a tri suit ensures that you have more buoyancy, which means that you have a higher position in the water. You also save energy by wearing a tri suit while swimming, because your body loses less heat. The energy you save can then be put in the cycling and running parts.

The investment for your first tri suit may put you off, but a tri suit pays itself back. For example, I could use my first tri suit ten (!) years. I would like to help you sort out the right tri suit, so you will find tips in this article to choose a suitable tri suit.

tri suit

The temperature of the water

When selecting the perfect tri suit, the temperature of the water is an important variable. If the water is very cold, it may be useful to carry a wetsuit over your tri suit. The wetsuit will keep you warm and helps you save valuable energy while swimming. If the water has a more pleasant temperature you can also choose not to use a wetsuit. In this case it is useful to choose a tri suit that dries quickly.

The weather during the triathlon

Especially in the Netherlands, the weather on the day of the triathlon is never a certain factor. If you want to prepare for the weather, it is important to think about the following matters. Most tri suits have built-in UV protection, it is important to find a tri suit that also has this. It is also important to wear a tri suit that is well ventilated.

Storage spaces

Consider carefully what you want to take with you during the triathlon. If you have a lot (food, sport drink, mobile phone for tracking your progress) with you, it could be useful to consider this when choosing your tri suit. Make sure that your belongings can not fall out of your pockets during the race.

Picking a tri suit in the right size

A tri suit that is too small can cause skin irritations and limited freedom of movement. On the other hand, a tri suit that is too large can slow you down in the water. So, make sure you have exactly the right size and practice a lot in your tri suit in advance.
