Open Water Swimathons: Overcoming Anxiety and Perfecting Your Stroke

With events like the Bergman Swimathon BLR (Sept 5, 2026, at Nelligudde Kere) and the swim leg of every triathlon on the calendar this season, plenty of pool-trained swimmers are about to face open water for the first time — or the first time in a while. The two biggest issues that show up aren't fitness problems. They're anxiety and technique adjustments specific to unpredictable water.

Why open water feels so different

No lane lines, no black line on the floor to follow, murky visibility, other swimmers making contact, and a real or perceived lack of "walls" to grab if you're tired — all of this triggers a stress response that has nothing to do with your actual swim fitness. Recognizing that this is a normal, common reaction (not a sign you're not ready) is the first step to managing it.

Building comfort before race day

• Get into open water more than once before your event. A single practice swim a week out isn't enough to desensitize the nervous system. If you can, do 3–4 open-water sessions in the lead-up, even short ones.
• Practice sighting in a pool first. Pick a point on the wall or ceiling, swim toward it, and lift your eyes every 6–8 strokes without breaking stroke rhythm. This builds the muscle memory before you need it in unpredictable water.
• Simulate contact. If you can swim with a training partner or group, practice swimming close to someone else on purpose — getting bumped or having someone swim over your legs is startling the first time it happens in a real race; less so if you've felt it before.
• Practice your breathing under stress, not just under exertion. A few sessions of deliberately elevating your heart rate (hard effort intervals) followed immediately by controlled, bilateral breathing helps train your body to stay calm when your heart rate spikes mid-swim — which it will, race morning, before you've even started.

In-the-moment anxiety tools

• Roll onto your back. If you panic mid-swim, this is always available and isn't a failure — floating on your back to catch your breath and reset is a normal, sanctioned strategy in every open-water event.
• Box breathing on the start line: inhale for 4, hold for 4, exhale for 4, hold for 4. A few rounds before your wave starts measurably lowers pre-race heart rate for most people.
• Start toward the back or side of your wave if crowd anxiety is a bigger issue for you than losing a few seconds — less contact in the first 200m goes a long way toward keeping your head clear.

Stroke technique for open water (vs. pool swimming)

1. Sighting without wrecking your rhythm. The classic mistake is lifting the head too high or holding it up too long, which drops the hips and kills momentum. Aim for a quick "alligator eyes" peek — just enough to see the buoy or shoreline — then straight back down.

2. A slightly higher stroke rate, shorter glide. Open water rewards a bit more turnover and a bit less gliding compared to pool technique, partly because you're constantly making small corrections for sighting and partly because there's no wall push-off to rely on for momentum.

3. Bilateral breathing flexibility. Even if you have a dominant breathing side in the pool, practice breathing to both sides. Wind, chop, and the position of the sun or other swimmers can make one side impractical on race day — you want the option.

4. Straight-arm or slightly wider catch for sighting swims. A wider entry point makes it a little easier to sight without disrupting your stroke line, useful when landmarks are hard to spot.

Race morning specifics

Arrive early enough for a short warm-up swim if the event allows it — even five minutes of easy strokes in the actual water settles both the nervous system and the muscles. And don't try anything new on race morning: new goggles, new wetsuit, new stroke drill — all of it should already be familiar by the time you're standing at the water's edge.
