Open Water Sighting Drill: Zigzag Navigation Practice

Session Overview

Navigation errors cost precious time on race day — this 45-minute open water session will sharpen your sighting skills through deliberate zigzag route practice. By intentionally swimming off-course and correcting back to your target, you’ll build the instincts to stay on line under race pressure. Best used in the weeks leading up to your first open water event.

What You’ll Need

• Open water access (lake, reservoir, or calm sea)
• Wetsuit (if water temperature requires)
• Swim safety buoy
• 2–3 visible buoys or markers set roughly 100m apart
• Training partner or safety kayaker (recommended)

Warm-Up (10 minutes)

Easy freestyle for 400m close to shore, focusing on relaxed breathing and long strokes. Practise sighting every 6 strokes during the warm-up — lift eyes forward just enough to spot a fixed point on shore, then return your face to the water immediately.

Main Set

Use 3 buoys in a rough triangle or zigzag layout (each ~80–100m apart). Complete the following pattern, practising deliberate course correction between each buoy:

• 3×zigzag loop (buoy A → B → C → B → A): sight every 4 strokes on approach, every 8 strokes on open water — 90 seconds rest after each loop
• 2×200m straight swim to a fixed point on shore, deliberately drift off course then correct at midpoint — 60 seconds rest between each
• 1×400m continuous open water swim with no deliberate drift — focus on maintaining straight line through consistent sighting rhythm

Cool-Down (5 minutes)

Easy 200m swim back to shore at low effort. Practise one final sighting pattern: sight every 10 strokes and track how well you stay on course when fatigued. Roll onto your back for 50m to relax your shoulders.

Coaching Notes

• When sighting, use a “crocodile eyes” technique — lift only your eyes above the water rather than your full head to minimise drag and hip drop
• The commonest mistake is sighting too infrequently on straight sections — a brief drift of 5 degrees over 100m adds 10–15 unnecessary metres to your race
• If you can’t see your buoy on the first sight, don’t panic — take two more strokes and try again before adjusting course
• Aim to sight before your breath stroke so you can instantly breathe afterwards without breaking rhythm
