Did you know that 15% of all triathlons are based in the sea, yet triathletes only train in the Sea 1-2 times before their race? We believe that's not enough to be fully prepared for everything the ocean throws at you, and have prepared a 5 Stage Open water Sea Swim Masterclass to bridge the gap for you

 

Learn how to go from pool swimmer to confident open-water athlete in 5 structured phases.

​

Are you training for IRONMAN 70.3 Weymouth, Bournemouth, or Portsmouth Tri, but feel anxious about the sea swim? The jump from a standard pool lane to the tidal swell of the Solent is huge.

​

The Coastal Mastery Course is a premium, 5-phase specialist program designed to systematically build your open-water confidence, technical efficiency, and race-day speed. By combining precision video analysis, Olympic-distance saltwater pool preparation, and real-world sea coaching, we eliminate the guesswork and the fear.

 

The 5-Phase Progression Framework

Phase 1: 1-to-1 Swim Video Analysis (Hilsea Lido - 66m)

​

We start by diagnosing your efficiency leaks. Using high-speed underwater cameras, we capture your stroke from multiple angles to identify exactly where you are creating drag or losing propulsion.

​

Focus: Core body position, hand entry, and catch mechanics.

​

Takeaway: A personalized digital stroke blueprint and specific correction drills before we move outdoors.

​

Phase 2: Open Water Pool Prep 1 (Hilsea Lido - 66m)

​

We take your refined stroke to the newly refurbished, 66m newly refurbished Hilsea Lido. This chlorinated saltwater environment provides the buoyancy of the sea without the waves or weeds.

​

Focus: CSS (Critical Swim Speed) pacing, straight-line sighting, and bilateral breathing comfort.

​

Phase 3: Open Water Pool Prep 2 (Hilsea Lido - 50m)

​

The final step before the ocean. We introduce race-specific variables in a controlled, safe environment.

​

Focus: Wetsuit buoyancy management, advanced sighting techniques for the sea, drafting techniques, navigating around turn-buoys, and group acclimatization.

​

Phase 4: Sea Insertion & Skills (Southsea Beach)

​

We transition into the sea at Southsea. You will learn to read the water and adapt your stroke mechanics to moving swell.

 

Focus: Wading, dolphin diving, conquering the shorebreak, currents, drifting, reading tides, and high-visibility horizon sighting.

 

Phase 5: The Race Simulation (Southsea Beach)

 

The final graduation session. We put every element together into a full-scale ocean race simulation.

 

Focus: Mass-start positioning, beach exits, tactical pacing, and building the mental resilience required to dominate your race day.
