Open-Water Sighting and Breathing Techniques

Most triathletes can swim 1500m comfortably in a pool. Yet on race day, they finish the swim exhausted, off-course, and shaken. The reason is almost never fitness — it's almost always sighting and breathing.

Bad sighting sends you on a zigzag path. A 1500m swim with poor sighting can become 1700–1800m of effort. That's 6–8 extra minutes for an average swimmer.

Bad breathing spikes your heart rate, triggers the panic reflex, and forces you to switch to breaststroke or stop. Most open water anxiety attacks start with one disrupted breath — water in the mouth, a wave to the face, contact with another swimmer.

The crocodile lift technique is the most efficient sighting method:

1. As your lead arm extends forward, lift your eyes only just above the water (think alligator eyes)
2. Take a quick visual snapshot of your sighting target
3. Drop your head back into neutral position
4. Roll to the side and take your normal breath

Key principles:

• Lift the eyes, NOT the whole head — full head lift drops your hips and slows you 15–20%
• Sight FORWARD before breathing, never combine into one motion
• Two quick sights are better than one long stare — use the second to confirm

When to sight:

• Calm water, clear buoys, daylight: every 12–16 strokes
• Choppy water or hidden buoys: every 6–10 strokes
• First 100m and around buoys: every 4–6 strokes

Sighting targets in priority order:

1. Buoys (the obvious target)
2. Tall landmarks behind buoys (lighthouse, building, tree)
3. The pack of swimmers (only if you trust them)
4. The sun position (for general direction)

Bilateral breathing (every 3 strokes) is taught as the gold standard, but it's a skill more than a race strategy. Use it for:

• Training and skill development
• Sighting both sides of the course
• Avoiding waves on one side

Unilateral breathing (every 2 strokes, one side) is what most triathletes actually use in races. It delivers more oxygen, calms the heart rate, and is fine if you can sight effectively.

The 3-2-3 pattern is the best of both worlds:

• 3 strokes, breathe left
• 2 strokes, breathe right
• 3 strokes, breathe left
• Repeat

This lets you breathe more often (every 2.5 strokes average) while still sighting both sides.

Breathing technique fundamentals:

• Exhale fully underwater — never hold your breath
• Begin exhale the moment your face enters the water
• Inhale through the mouth corner (not the top of the mouth)
• Trick: try to see your shoulder when you breathe — keeps the head low

Cold water modification:

• Splash cold water on your face for 30s before entering — triggers the dive reflex acclimation
• First 100m: breathe every 2 strokes minimum
• See wetsuit swimming speed for cold water gear advice

Drill 1 — Pool sighting (eyes closed)

• Swim 25m with eyes completely closed
• Open at the wall to see how straight you stayed
• Goal: stay within one lane line of center

Drill 2 — Crocodile lift

• Every 6 strokes, lift just the eyes, look at the wall ahead
• Drop head, breathe to the side
• 4×100m with this pattern

Drill 3 — Bilateral build

• Week 1: every 3 strokes for 200m
• Week 2: every 3 strokes for 400m
• Week 3: alternate 200m bilateral, 200m unilateral

Drill 4 — Bubble exhale

• Sit at the wall, face in water
• Exhale slowly for 5 full seconds — you should still have air
• Most beginners exhale far too fast

Drill 5 — Open water simulation (in pool)

• Wear your wetsuit
• Swim with one or two friends in the same lane (controlled chaos)
• Practice sighting toward a fixed object outside the pool through the windows

5 minutes before start:

• Splash water on face 5–6 times to acclimate
• Identify 2–3 sighting landmarks (buoys + tall background object)
• Note where the sun will be — sight away from it when possible

First 200m:

• Start wide and slightly behind the pack if you're nervous
• Breathe every 2 strokes minimum
• Sight every 6 strokes until you find your rhythm

Middle of the swim:

• Settle into 3-2-3 breathing pattern
• Sight every 8–12 strokes
• Draft if you can (saves 10–20% energy)

Around buoys:

• Sight every 4 strokes from 50m out
• Take the inside line if you're confident, outside if you want clean water
• Resist the urge to sprint around buoys — go wide, smooth, and steady

Final 200m to swim exit:

• Sight every 6 strokes — exit lines are easy to miss
• Start gentle kicking to send blood to legs for T1
• Stand only when your hand brushes the bottom
