Mastering the Waves: Essential Swim Workouts for Triathletes
May 31, 2024

Swimming always comes first in a triathlon before the cycling and running segments of the race. Because of this, many athletes argue that it's the most important part of the entire event. It's where the front-runners can move away from the pack and gain an instant edge over their rivals.
Scientific studies back this up, showing that swimming ability is one of the best indicators of overall triathlon success, with overall event winners often emerging among the first pack of swimmers.
At the same time, many experts also agree that the swim is the hardest part of race day. Because it involves all major muscle groups, it can take a lot out of even the most experienced and in-shape athletes!
Therefore, if you want to improve your odds of triathlon success, it makes sense to work on your swimming abilities. In this guide, we'll look at key swim workouts for triathletes, covering every type of triathlon swim, from Olympic distance events to sprint triathlons.
Understanding Triathlon Swimming
First, let's examine the basics of triathlon swimming and the unique challenges it poses to competitors.
As stated, swimming is the first part of any triathlon. This means you enter it feeling fresh, with maximum energy, unlike the latter stages. However, this can be a double-edged sword. Given that athletes feel fit and excited at the start, many struggle to maintain a moderate pace. They let the rush of adrenaline hit them too hard, expending excessive energy early on that could ruin the rest of their race.
Another issue with the swim section is that it's often in open water. Conditions can be unpredictable and even dangerous, with the possibility of waves, currents, wind, and more. Additionally, you're often just one individual in a mass swim start. With so many others hitting the water simultaneously, it's easy to feel crowded or lose your bearings.
Thus, swim practice is crucial. Proper training helps build strength, endurance, and speed. It also gives you more confidence and control in the water, key for navigating crowds, finding your way to shore, and maintaining a steady, stable pace.
The Building Blocks of Triathlon Swim Training

We can break triathlon training down into four key components.
Endurance Training
Endurance training focuses on building stamina and helping you swim longer distances without getting worn out or expending excessive energy. Its main goals are to help you last longer in the water and build lung capacity.
Typical endurance-oriented workouts will focus on steady-state swims, where you aim to maintain a steady pace across a relatively long distance. Over time, you'll build up to longer distances.
Speed and Interval Training
Speed training is all about maximizing your pace in the water, crucial for quick sprints to the next leg. This is particularly important if you're preparing for sprint-style triathlon events, where rapidity is essential.
Typical speed and interval drills focus on quick, short, intense bursts of swimming with minimal breaks. Focus on getting through the water as quickly as possible without wearing yourself out with overly long sessions.
Technique and Efficiency
Mastering your stroke and kick techniques is crucial to maximize your distance and reduce the effort needed to reach and maintain a good pace.
Technique training involves drills like super slow swimming, where you focus entirely on movements and body position rather than speed. Closed-fist swimming is another drill to try, which can help you master your arm movement.
Open Water Skills
You most likely train in a pool, but will do your triathlon swimming in open water. That's a tricky transition, as the two are quite different, especially with the mass, crowded starts of a typical triathlon.
Try drills like diving into the water and swimming alongside a few other people to mimic the mass start, or swimming some lengths with your eyes closed to help you cope with the often-dark waters of lakes and seas. Additionally, attempt to practice in real open water before the big event, so it won't be such a shock.
Tailoring Workouts to Triathlon Distances

There are different types of triathlons, separated according to distance into the following categories: sprint, Olympic, half-Ironman, and Ironman (or full triathlon). In a sprint event, for example, you'll swim a fraction of the distance you'd handle in an Ironman. As such, it's important to tailor your workout regimen to suit the type of triathlon you're facing.
Sprint Distance Focus
A sprint triathlon involves a modest 750m swim leg. As the name implies, this is all about speed, and the top athletes will race through the water as fast as possible, holding little in reserve. Training for an all-out sprint should focus on speed and technique to help you glide through the water with grace and rapidity.
Olympic Distance Prep
For an Olympic triathlon, you'll have to swim nearly a mile (0.93 miles, or 1.5km, to be exact). That's still a relatively short distance compared to tougher triathlons, but training should incorporate a mix of speed and endurance management.
Half-Ironman Training
For a half-Ironman, the swim leg measures up to 1.2 miles. This is where endurance becomes more important than speed. Focus your training on managing your pace and controlling your breathing to help you go the distance.
Ironman Conditioning
For a full Ironman, you have to swim 2.4 miles. That's a massive distance in the water, and endurance is the priority here. Training should focus almost entirely on maximizing stamina and conserving energy.

Incorporating Swim Workouts Into a Triathlon Training Plan
Donning your swim jammers and working out in the water is a critical part of triathlon prep. But it's not the only part. You also have to prepare for the rest of the race — the running and cycling legs. A balanced approach is crucial to maximize your returns and increase your odds of success.
So, don't dedicate too much of your time and energy to the pool. Instead, try to establish a harmonious workout plan, allocating equal time to all three disciplines. Swim one day, run the next, then cycle the day after, for example. Remember to take rest days too and don't push yourself too hard to avoid injury.
Equipment and Tools for Effective Swim Training
To get the most from your swim training, it helps to have the right gear. That begins with your attire. Professional-grade competition swimsuits and tech suits are essential. They'll help you glide through the water with a full range of motion and minimal resistance, helping you hit your target race pace and stroke count more easily.
Experienced racers will buy their triathlon swimsuits well before race day and spend lots of time in them, getting familiar with their feel and flow. The best women's and men's competition swimwear should also include a set of goggles to help you see clearly underwater and fins to propel you along. Pull buoys are also useful when you're focusing purely on arm and upper body training.
You may also want to invest in apps and other tech tools, like swim watches, to help you track your progress, measure your speed, and identify potential areas of improvement.
