Triathlon Sighting Technique: Navigate Open Water

Master sighting in triathlon swimming. Learn how to lift your head efficiently, spot landmarks, and swim straight in open water races.

Sighting in triathlon swimming means briefly lifting your head to spot the next buoy, ideally every 6-10 strokes, while maintaining your stroke rhythm and forward momentum.

Good sighting is the difference between swimming the shortest distance and adding minutes to your swim split. It's a skill that must be practiced.

Why Sighting Matters

The Math

If you swim just 5% off course:

  • 750m swim (Sprint) → 37.5m extra
  • 1,500m swim (Olympic) → 75m extra
  • 1,900m swim (70.3) → 95m extra
  • 3,800m swim (Ironman) → 190m extra

At 2:00/100m pace, a 5% deviation costs:

  • Sprint: 45 seconds
  • Olympic: 1:30
  • 70.3: 1:54
  • Ironman: 3:48

Swimming straight is free speed.

The Sighting Motion

Step-by-Step Technique

1. Initiate during regular stroke

  • As your lead hand enters the water
  • Before your face would normally rotate for breath

2. Lift eyes (not entire head)

  • Eyes come out of water
  • Chin stays near surface
  • Quick, smooth motion
  • Like an alligator peering above water

3. Quick look forward

  • One second maximum
  • Spot your target
  • Process the information

4. Return to stroke

  • Head drops back into position
  • Rotate to breathe if needed (same stroke or next)
  • Adjust direction if necessary

The "Alligator Eyes" Cue

Think of how an alligator lifts just its eyes above water:

  • Minimal head lift
  • Eyes barely break surface
  • Quick scan
  • Returns underwater

NOT:

  • Lifting head high
  • Looking around extensively
  • Full head out of water
  • Lifting chest

What to Look For

Primary Targets

Target TypeExamplesWhen to Use
Large landmarksBuildings, trees, mountainsMain navigation
BuoysCourse markersDirection confirmation
Other swimmersPack aheadQuick reference
Swim exitBeach, dockFinal navigation

Landmark Selection

Before the race:

  1. Study the course from shore
  2. Identify large, visible landmarks behind each buoy
  3. Note the exit location
  4. Remember landmark order for turns

Good landmarks:

  • Tall buildings
  • Trees on horizon
  • Mountains/hills
  • Flags or banners
  • Colored structures

Bad landmarks:

  • Other swimmers (they move)
  • Small buoys (hard to see)
  • Low objects on shore
  • Temporary items

Sighting Frequency

General Guidelines

ConditionsSight EveryReason
Calm, clear10-12 strokesLess drift
Moderate chop8-10 strokesHarder to see
Rough water6-8 strokesMore drift, less visibility
Crowded startEvery few strokesChaos navigation
Near turnsEvery 4-6 strokesPrecision needed

Adapting to Conditions

When to sight more:

  • Poor visibility
  • Strong current/wind
  • Near buoys or turns
  • If you tend to drift
  • Early in race (finding rhythm)

When to sight less:

  • Calm conditions
  • Clear landmarks
  • Following trusted swimmer
  • Long straight sections

Common Sighting Mistakes

Mistake 1: Lifting Too High

Problem: Head and shoulders come out of water Result: Hips sink, lose momentum, exhausting Fix: Eyes only, chin near surface

Mistake 2: Looking Too Long

Problem: 2-3 seconds looking around Result: Slows down, rhythm breaks Fix: One second max, quick glance

Mistake 3: Only Sighting Buoys

Problem: Buoys are small and hard to see Result: Miss buoy, go off course Fix: Use large landmarks behind buoys

Mistake 4: Not Sighting Enough

Problem: Sight every 20+ strokes Result: Significant course deviation Fix: Build sighting into stroke rhythm

Mistake 5: Stopping to Sight

Problem: Stop swimming to look Result: Lose momentum, slower time Fix: Sight while swimming

Integrating Sighting with Breathing

Option 1: Sight-Then-Breathe

  1. Lift eyes forward (sight)
  2. Drop head back
  3. Rotate to breathe (same stroke)
  4. Continue swimming

Best for: Rough water, when you need to see clearly

Option 2: Continuous Motion

  1. Lift eyes forward as arm pulls
  2. Rotate head to side to breathe
  3. Continuous head rotation
  4. No pause

Best for: Calm water, when efficient rhythm matters

Practice Both

Different conditions require different techniques. Master both.

Practice Drills

Drill 1: Pool Sighting

In the pool:

  1. Swim normal freestyle
  2. Every 6-8 strokes, sight end of pool
  3. Practice minimal head lift
  4. Time full length with and without sighting

Drill 2: Closed-Eye Navigation

Purpose: Understand natural drift

  1. Swim 8 strokes with eyes closed
  2. Open eyes, sight forward
  3. Note how far off course you went
  4. Adjust for natural drift tendency

Drill 3: Landmark Sighting

In open water:

  1. Identify landmark on shore
  2. Swim toward it, sighting every 8 strokes
  3. Check accuracy at intervals
  4. Adjust technique as needed

Drill 4: Sighting Under Fatigue

Late in workout:

  1. Swim continuous 400-800m
  2. Include sighting every 8-10 strokes
  3. Maintain technique when tired
  4. This is race simulation

Race Day Sighting Strategy

Pre-Race Course Study

Do before start:

  1. Stand at swim start
  2. Identify first buoy
  3. Find landmark behind first buoy
  4. Repeat for each turn
  5. Note exit location

First 200 Meters

  • Sight frequently (every 4-6 strokes)
  • Find clear water
  • Establish direction
  • Don't follow blindly

Mid-Race

  • Regular sighting rhythm (8-10 strokes)
  • Use landmarks more than buoys
  • Adjust for current if present
  • Don't get complacent

Near Turns

  • Increase sighting frequency
  • Know which side buoy should be on
  • Don't cut buoys short
  • Watch for other swimmers

Final Approach

  • Sight the exit
  • Swim until hands touch bottom
  • Prepare for T1

Dealing with Low Visibility

When You Can't See

Causes:

  • Waves
  • Sun glare
  • Rain
  • Low-sitting buoys

Solutions:

  1. Sight more frequently
  2. Use tallest landmarks available
  3. Follow other swimmers (carefully)
  4. Trust your stroke direction
  5. Stay calm

Sun Glare Tips

  • Know sun position before start
  • Have tinted or mirrored goggles as backup
  • Sight to side of sun if possible
  • Use other reference points

Open Water Practice

Before race day:

  • At least 4-6 OWS sessions
  • Practice at race venue if possible
  • Simulate race sighting patterns
  • Practice in various conditions
