Q: I feel great in the pool. I hit my intervals, I can swim distance, and honestly, I thought the swim would be my strength. But the minute the horn goes off in open water, my heart starts racing, my breathing gets weird, and I feel borderline panicked. What is happening and how do I fix it?
A: I’ve talked to first-time sprint athletes, Kona qualifiers, and everyone in between who has had this exact experience. Being strong in the pool does not automatically mean you’ll feel calm on race morning. Open water is a completely different animal and your brain knows it.
In a pool, everything is controlled. You can see the bottom. You’ve got your lane. There’s space. If you need a second, you grab the wall. Race morning? Different story.
Now you’re shoulder-to-shoulder with a few hundred of your newest friends. People are kicking, arms are flying, goggles get knocked, the water might be cold, and you can’t see much of anything. Your brain reads all of that as a potential threat and hits the gas on your fight-or-flight response. Heart rate spikes. Breathing shortens. Stroke falls apart. This isn’t a fitness issue — it’s sensory overload.
You may be starting hard. Here’s one of the biggest mistakes I see: strong swimmers treating the first 200 yards like it’s a sprint. Adrenaline is pumping, everyone surges forward, and before you know it you’re swimming way above your sustainable effort. Once your breathing gets out of control in the water, panic isn’t far behind.
The fix is simple, but not always easy: Start slower than you think you need to. Give yourself two or three minutes to settle in. Let your breathing find a rhythm. Then build into your effort. The athletes who look smooth out there? They didn’t accidentally find that pace — they chose it.
Clear water is fast water. There is zero prize for starting front and center if it means you spend the next five minutes getting swum over. If you tend to get anxious, seed yourself a little wider or a row back. Yes, you might swim a few extra yards. You know what you won’t be doing? Fighting for oxygen.
If You Feel Panic Rising, Reset. Even experienced athletes do this. Roll onto your back for a few seconds. Switch to breaststroke. Lift your head and take a couple controlled breaths. That is not failure; it is smart racing.
The biggest thing I want you to focus on is the exhale. When athletes panic, they often hold their breath without realizing it. Long, intentional exhales tell your nervous system to calm down. You’d be amazed how quickly your heart rate drops.
Warm Up. Please. Jumping straight into a race at full effort is a shock to the system. If the race allows it, get in the water for even five minutes beforehand. Put your face in. Blow bubbles. Get your breathing under control. No swim warmup available? Do some light cardio on land and focus on steady breathing. Just don’t let the race start be the hardest effort your body has felt all morning.
Train for Reality. Pool fitness is great. But comfort comes from familiarity. If you can, practice in open water. Learn what your stroke feels like without that black line guiding you. Get used to sighting. Experience a little chaos before race day. No lake nearby? Simulate stress in the pool. Swim continuous instead of stopping at the wall. Share a crowded lane. Take away some of that predictability.
Bad goggles and a too-tight wetsuit can turn manageable nerves into full-blown stress. Choose goggles that match the conditions so you can actually see. And your wetsuit should feel supportive; not like it’s squeezing the life out of your rib cage. If you can’t breathe comfortably on land, it’s not getting better in the water. Comfort equals speed. Every time.
The swim isn’t something to survive. It’s your chance to start the day controlled, smooth, and confident. Even veteran triathletes get those “whoa, okay” moments in open water. The difference is they don’t fight it, they manage it.
Start calm. Control your breathing. Do that, and the swim stops feeling chaotic and starts feeling like momentum. Once that happens, the rest of your race tends to go a whole lot better.
