Open Water Swim: 1500m Race Simulation

Session Overview

This 45-minute open water session simulates the full 1500m Olympic race-distance swim. You will practise sighting, pacing, and managing effort under race-like conditions to build confidence ahead of your next triathlon.

What You’ll Need

• Triathlon wetsuit (or swimsuit for warm water venues)
• Open water swim safety buoy
• GPS watch to track distance and pace
• A supervised open water venue or swimming buddy

Warm-Up (8 minutes)

Enter the water and swim easy freestyle for 5 minutes, focusing on relaxed breathing and settling into the open water environment. Spend the final 3 minutes on sighting drills, lifting your head every 6 strokes to spot a fixed distant marker.

Main Set

Complete a continuous 1500m swim at your target race pace. Aim for an even effort throughout — resist the urge to go hard at the start. Use this mental breakdown to stay on track:

• First 300m: Easy, controlled start — settle into your rhythm and establish a sighting routine every 6 to 8 strokes
• Next 600m: Build to race pace — smooth, efficient strokes, consistent sighting, relaxed shoulders
• Next 400m: Hold race pace — maintain rhythm, focus on high elbow catch and strong pull
• Final 200m: Strong finish — increase effort to 8.5/10 RPE, drive through to the exit point

Cool-Down (5 minutes)

Easy backstroke or light freestyle for 5 minutes, focusing on controlled breathing and gradually lowering your heart rate. Practise your race swim exit — stand, remove your goggles and cap, and walk briskly to simulate the transition run.

Coaching Notes

• Sight to fixed landmarks such as buoys or buildings rather than constantly scanning the horizon
• Avoid the common mistake of sprinting the first 200m — you will pay for it in the final quarter
• Beginner option: break into 3 x 500m with 60 seconds rest between each effort
• Target RPE: 6-7/10 for the middle 1000m, building to 8.5/10 in the final 200m
