Open Water and the Swim Panic Nobody Warned You About

By Coach Finn

Let me start with the thing I wish someone had said to me before my first open water swim, because it would have saved me a lot of fear and a little bit of shame.

If you feel calm and capable in the pool, then you stand in a lake or the sea, look out at the dark water, and feel your heart start to climb into your throat, you are not broken. You are not weak. You are not secretly a bad swimmer who has been fooling everyone. You are a completely normal human being whose body is doing exactly what it is built to do. Almost everyone who has ever stood where you are standing has felt some version of it. Strong swimmers. Lifeguards. People who have done this for years.

So before we go one step further, I want you to breathe out slowly and read that again. The fear is normal. We are going to work with it, not pretend it away. And we are never, ever going to rush you.

This is the chapter I care about most in this whole book, because it is the one that keeps you safe and keeps you in the sport. Take your time with it.

Why does open water scare me when I am fine in the pool?

Here is the honest answer: open water is not the same activity as pool swimming. It looks similar. You are still moving your arms and breathing and kicking. But almost everything your brain quietly relied on in the pool has been taken away.

In the pool you always have a black line on the bottom telling you where to go. You have lane ropes on both sides, a wall every twenty five metres, and a clear, lit, bottom you can see and stand on. You are never more than a few strokes from safety, and you know it without thinking about it. That knowledge is doing a huge amount of work to keep you calm.

Open water removes all of it at once.

There is no line to follow, so you have to navigate. There are no walls to grab and rest on, so stopping feels different. The water is often dark or murky, so you cannot see the bottom, and for a lot of people that single thing, the not seeing, is the trigger. Your brain does not like unknown space beneath you. That is ancient wiring, and it is not a character flaw.

Then there are the things that are actively new and physical.

The cold water gasp. When you get into water colder than roughly 15 degrees Celsius (about 59 Fahrenheit), your body can react with an involuntary gasp and fast, shallow breathing. This is called cold water shock, and the gasp reflex is automatic. It is not you panicking, it is your nervous system reacting to cold skin. The danger is that a gasp with your face in the water pulls water in, which then triggers the real panic. The good news, and I will keep coming back to this, is that this response peaks in about the first 60 to 90 seconds and settles within two to three minutes if you stay calm and let it pass.

The washing machine. In a race start, you are suddenly surrounded by other bodies, arms, and feet, in churning water, with no personal space. People call it the washing machine for a reason. Even confident swimmers can feel claustrophobic and overwhelmed in it. We will plan for that later in the chapter so it never has to be a surprise.

So when you feel fear in open water, you are not failing at swimming. You are meeting a genuinely harder, more stimulating environment for the first time, with none of your usual safety cues. Of course your body reacts. The work is not to never feel it. The work is to expose yourself to it slowly, on your terms, until your brain learns that this water is safe too.

How do I practice open water safely, step by step?

The single most important rule in this entire chapter: never swim open water alone. Not once. Not "just a quick one." Not even if you are a strong pool swimmer. Open water always means a buddy, a supervised venue, or both. This is the rule the experts never bend, and neither do we.

With that locked in, here is how we build you up gradually. The whole idea is progressive exposure. You give your nervous system small, manageable doses of the new environment and let it adapt between each one. You are training your brain as much as your body.

Step 1: Get pool competent first

We do not start here in open water at all. CouchToTri builds your open water work only after you can swim comfortably and continuously in a pool. If you cannot yet swim a few hundred metres relaxed in a pool, that is your job first, and that is a good and worthy job. Open water is a layer we add on top of competence, never a shortcut around it.

Step 2: Choose a supervised, controlled venue

For your first sessions, go to a lifeguarded open water swim venue or an organised session with safety cover, not a random lake or a quiet bit of coast. Look for a place with marked areas, a shallow zone, and people watching the water. This removes most of the real risk while you do the scary feeling part.

Step 3: Just get in. That is the whole session.

Your first time, the goal is not to swim. The goal is to get in to waist or chest depth, splash water on your face and the back of your neck, and let your body meet the cold. Stand there. Breathe. Put your face in for a second and lift it. Get used to not seeing the bottom. That is a complete, successful session. Walk out proud.

Step 4: Short swims parallel to shore

Once getting in feels okay, start swimming short distances parallel to the shore in water shallow enough to stand up in. Swim ten or twenty strokes, stand, breathe, swim again. Staying parallel and shallow means safety is always one step away, which keeps your brain calm while it learns.

Step 5: Add a little distance and a little depth

Gradually, over several sessions, you lengthen the swims and move slightly further out, always with supervision, always able to get back easily. You let comfort lead and distance follow, not the other way around.

A word about "just push through it." You will hear that advice, and it is wrong for open water. Forcing yourself, alone or unsupervised, into water that is terrifying you does not build confidence, it builds a bad association and it can be genuinely dangerous, because panic in deep water is how strong swimmers get into trouble. We do not push through panic. We turn the dose down, recover, and try a smaller step next time. Backing off is not failure. Backing off intelligently is the skill.

What do I do if I panic during the swim?

This is the part to read twice, then read again before any open water session, until it is automatic. When panic hits in the middle of a swim, you do not need to fix it with willpower. You need a simple protocol your body can run even while your mind is loud. Here it is.

The stop, float, reset protocol

Stop. Stop swimming. You do not have to keep going. There is no rule that says you must swim freestyle the whole way.

Float. Roll onto your back. Spread your arms and legs a little, tilt your head back, and let yourself float, looking up at the sky. If you are in a wetsuit, and for open water you usually will be, this is almost effortless. The wetsuit will hold you up. You genuinely cannot easily sink in one. Let it do the work while you do nothing.

Reset. Now breathe. The key is a long, slow, controlled exhale, not a big desperate inhale. Panic makes you over breathe and gulp air, which makes things worse. So you focus only on breathing out slowly and fully, and let the in breath take care of itself. Three or four of those and you will feel your heart rate start to come down. This is the same "float to live" idea that water safety services teach, and it works because floating buys you time while the panic chemistry burns off.

Stay on your back as long as you need. Seconds, or a full minute. Nobody is timing you. When you feel steadier, you have options.

Your recovery gears

You do not have to go straight back to full freestyle. You have gentler gears:

  • Breaststroke with your head up, calm and slow, keeping your face out of the water and your eyes on the horizon. This is your reset stroke.
  • Heads up freestyle, sometimes called water polo style, where you swim freestyle but keep your head up to stay oriented and reassured.
  • Back float and gentle backstroke to keep moving toward safety while still resting.

Switch into any of these whenever freestyle feels like too much. Many experienced triathletes break up a hard or anxious swim with little stretches of breaststroke, and there is zero shame in it. Finishing calm beats finishing fast every single time.

The thing to hold onto is this: in open water, in a wetsuit, you always have an out. You can always stop and float. Once you truly believe that, in your body and not just on paper, a huge amount of the fear loses its grip, because the worst case (I cannot cope and I am stuck) is simply not true. You are never stuck. You can always roll over and breathe.

How do I swim straight without a black line to follow?

In the pool the line shows you the way. In open water you navigate yourself, and the skill that does it is called sighting. Done well, it keeps you swimming straight, which saves you energy and stops the disorienting feeling of looking up and finding you have drifted way off course.

The alligator eyes lift

The technique is simple and it has a lovely name: alligator eyes, or crocodile eyes. Picture an alligator with just the top of its eyes above the waterline. That is you. As your hand enters and you start the pull, you lift your head just enough to get your eyes (not your whole face) above the surface, take a quick glance forward, then drop your face back down and turn to breathe to the side as normal.

The two big mistakes are lifting your whole head, which pushes your legs and hips down and tires you out, and holding the lift too long. Keep it quick and low. Eyes up, snapshot, face back down.

How often, and what to aim at

How often you sight depends on the water:

  • In calm water, sight roughly every six to ten strokes.
  • In choppy water, sight more often, every three to five strokes, because you drift faster and your view is blocked by waves.

A reliable pattern is to take two or three quick sights in a row: the first to find your target, the second to adjust your line, the third to confirm. Then put your head down and swim straight for twenty or thirty seconds before doing it again.

Aim at the big, obvious marker buoys on the course, and where you can, line them up with a tall, fixed landmark on shore behind them, a building, a tree, a hill. Fixed landmarks are better references than other swimmers or boats, which move. Practise sighting in your supervised sessions so it is a habit long before race day, not a panicked guess on the day itself.

Do I need a wetsuit?

For open water, especially anywhere cool, my strong answer is yes, and not mainly for speed. The wetsuit is a safety and confidence tool first.

Here is what it does for you.

It makes you float. Neoprene is full of tiny trapped air bubbles, so a triathlon wetsuit lifts you toward the surface. This is the single biggest reason it calms anxious swimmers. You are harder to sink, your legs ride higher so swimming is easier, and your stop, float, reset move becomes almost effortless. The wetsuit will not let you go under easily, and knowing that changes everything in your head.

It keeps you warm. It traps a thin layer of water against your skin that your body warms, which blunts the cold and reduces the gasp shock when you get in. Warm and buoyant is a much calmer place to start from.

It buys you time and visibility of safety. Because you float, if you tire or wobble, you can rest on your back almost indefinitely rather than fighting to stay up.

A few practical notes so the suit helps rather than hinders:

  • Fit matters. It should be snug everywhere, like a firm hug, with no big gaps at the lower back where water pools, but never so tight at the shoulders and chest that it restricts your arms or your breathing. Do some big arm circles in the shop or before the swim. If your shoulders feel choked or you cannot fill your lungs, it is too small there.
  • Practise in it before race day. A wetsuit changes how your stroke feels, how you breathe, and how high you float. Do several supervised swims in it so race day is not the first time. Never debut new kit on race day.
  • Practise getting it off. Peel it down to the waist quickly, then step out. Practise this on dry land and after a swim, because fumbling with a stuck wetsuit, cold and tired, is its own little stressor you can simply remove with a few rehearsals.

If your race is wetsuit legal, which most beginner friendly ones are, wear it. It is one of the kindest things you can do for your nervous system.

What safety gear and conditions should I check?

Open water rewards a little planning. Run through this before you swim, every time.

Water temperature. Know it. Cold water, below about 15 degrees Celsius, brings the gasp reflex and faster heat loss. Cold means a slower entry, a wetsuit, shorter swims, and getting out before you are deeply chilled, not after.

A bright tow float and a bright swim cap. A tow float is a small inflatable buoy you clip around your waist that trails behind you. It does not slow you down, it makes you highly visible to boats and lifeguards, and you can grab it and rest on it if you tire. Wear a brightly coloured cap too. One honest caveat: a tow float is a visibility and rest aid, not a lifejacket. It helps you be seen and gives you something to hold, but it does not replace all your other safety habits.

Conditions. Check wind, waves, currents, and tides before you get in. Choppy, windy, or strong current days are not the days to push your limits or try something new. If in doubt, do less, or do not go in. The water will be there tomorrow.

Supervision. Swim where there is a lifeguard, or with a kayak or paddleboard escort, or as part of an organised session, or at the very least with a buddy who stays with you. Tell someone where you are and when you will be back.

Know your exits. Before you swim, look at the shore and pick the points where you can easily get out. Knowing exactly where you would head if you needed to leave the water is hugely calming, and occasionally vital.

None of this is about being fearful. It is about being prepared, which is the opposite of fearful. Prepared people relax.

How do I survive the race start when I am anxious?

The mass start is the part beginners dread most, so let us take the fear out of it with a plan. You do not have to fight for position. You have permission to make the start as gentle as you want.

Seed yourself at the back or to the side. This is the big one. You do not have to be in the middle of the scrum. Start at the rear, or off to one side, where there is open water and far fewer arms and feet around you. You give up nothing that matters to you, and you gain calm, clear water.

Use rolling starts when offered. Many races now use a rolling or self seeded start, where small groups enter the water a few seconds apart rather than everyone at once. If your race offers this, it is a gift for an anxious swimmer. Seed yourself slow, near the back, and you will swim in space.

Give yourself a head start of calm. Even in a wave start, you are allowed to wait. Let the front pack surge ahead, count a few seconds, and follow into cleaner water. A handful of seconds costs you almost nothing and buys you a far calmer first minute, which is exactly the minute that matters most.

Then swim one buoy at a time. Do not think about the whole distance at the start line, it will feel enormous. Think only about reaching the first buoy. Then the next. Each buoy is a small, finished thing. Breaststroke between them if you want to. Float and reset if you need to. The swim is just a series of short trips between markers, and you only ever have to do the one you are on.

A soft word to finish

I want to leave you with the same gentleness we started with.

At CouchToTri we build open water readiness slowly, and only after pool competence, on purpose. We will never put you in deep, dark, cold water and tell you to be brave. We add open water as a careful layer once you can swim relaxed in a pool, and then we expose you to it in small, supervised, repeatable steps until your brain quietly decides this water is safe too. That decision cannot be forced. It can only be earned, one calm session at a time, and it always comes.

So if today the open water scares you, that is not a sign you are not cut out for this. It is just where you are starting. Every open water swimmer you admire started exactly there, heart in their throat, looking at dark water, wondering if they could.

They could. So can you. Slowly, safely, with a buddy beside you and the wetsuit holding you up. Stop, float, breathe out, one buoy at a time.

If you want me walking you up to that water one calm step at a time, that is exactly what I do at couchtotri.com, and it is free to start. We will earn the open water together, slowly, in the only way that ever truly lasts.

I will see you out there, and we are in no hurry at all.
