Open Water Swimming: Techniques, Navigation, Strategy, and Training for Speed

How can I swim faster in open water?

To swim faster in open water, focus on optimizing your stroke technique for efficiency, mastering precise sighting and navigation, developing a strategic race plan, and incorporating open water-specific training with a strong emphasis on mental fortitude.

The Unique Demands of Open Water Swimming

Open water swimming presents a dynamic environment vastly different from the controlled conditions of a pool. Variables such as currents, waves, water temperature, visibility, and the absence of lane lines or walls necessitate a specialized approach. To achieve optimal speed, swimmers must adapt their biomechanics and strategy to these unpredictable elements.

Technique Refinement for Open Water Efficiency

While fundamental swimming mechanics remain constant, open water demands subtle adaptations to maximize propulsion and minimize drag.

• Streamlined Body Position: Maintaining a high, horizontal body position is paramount. Engage your core to prevent your hips and legs from sinking, reducing drag. Your head position, while crucial for sighting, should return to a neutral, face-down position between sights to keep the body aligned.
• Effective Catch and Pull: Focus on a high-elbow catch, ensuring your forearm and hand act as a paddle to "grab" as much water as possible. Drive the pull phase all the way through to your hip, maximizing the propulsive force. Avoid "slipping" through the water; feel the pressure on your hand and forearm.
• Strategic Kick: In open water, an overly powerful, energy-consuming kick can be counterproductive, especially over longer distances. Develop a strong, consistent two- or four-beat kick for balance and minor propulsion, conserving leg energy for the bike or run (in triathlon) or a final sprint.
• Bilateral Breathing: The ability to breathe to both sides is invaluable in open water. It helps maintain stroke balance, prevents muscular imbalances, and allows you to adapt to changing wind, wave, or sun conditions that might make breathing to one side difficult. Fully exhale underwater before rotating to inhale.

Mastering Sighting and Navigation

Efficient navigation is a significant determinant of open water speed. Swimming off course can negate any technical advantage.

• Regular, Minimal Sighting: Aim to sight regularly but efficiently. Instead of lifting your entire head, practice the "crocodile eyes" technique: lift your eyes just enough to clear the water surface, quickly spot your target, and return your head to a neutral position. The frequency of sighting depends on conditions, but every 6-10 strokes is a common guideline.
• Target Selection: Identify large, stationary landmarks beyond the buoys for more stable reference points. Look for unique buildings, trees, or geographical features.
• Drafting: Swimming directly behind or slightly to the side of another swimmer can save significant energy (up to 20-30%). Learn to identify good drafters and practice maintaining close proximity without interfering with their stroke. Observe their pace and choose a swimmer slightly faster than your comfortable pace.
• Buoy Turns: Practice approaching and rounding buoys efficiently. Aim for the inside line, but be prepared for congestion. Maintain stroke rhythm through the turn rather than pausing or slowing down excessively.

Pacing and Race Strategy

A well-executed race plan is critical for sustained speed and optimal performance.

• Strategic Start: The initial moments of an open water swim can be chaotic. If you prioritize speed, position yourself strategically to minimize contact and find clear water quickly. This might mean starting wide, or being aggressive initially to get ahead of the pack.
• Consistent Effort Distribution: Avoid going out too fast and "bonking" later. While an initial surge can help find clear water, settle into a sustainable, strong pace that you can maintain for the duration. Consider a negative split strategy where the second half is slightly faster than the first.
• Energy Conservation: Beyond drafting, be mindful of your effort. Conserve energy where possible, only increasing effort for strategic moves like pulling away from a pack or during the final approach to the finish.

Open Water-Specific Training

Your training regimen must simulate the demands of open water.

• Open Water Practice: If accessible, regularly swim in open water. This helps you acclimate to the environment, practice sighting, drafting, and navigating, and build confidence away from pool walls.
• Long-Distance Endurance: Incorporate longer, continuous swims at race pace to build the aerobic capacity required for sustained effort.
• Interval and Threshold Training: Include sets of high-intensity intervals and threshold swimming to improve your speed and lactate tolerance. These can be done in the pool but should be adapted to mimic open water efforts (e.g., long intervals without wall pushes).
• Strength and Conditioning: A strong core, powerful lats, and mobile shoulders are crucial. Incorporate dry-land exercises like pull-ups, rows, planks, and rotator cuff strengthening to support your swim stroke.
• Brick Workouts (for Triathletes): Practice swimming immediately followed by biking or running to simulate race day fatigue and prepare your body for transitions.

Equipment Considerations

While skill is paramount, the right equipment can provide a marginal gain.

• Wetsuit: For colder water or for buoyancy assistance, a well-fitting wetsuit can significantly reduce drag and provide warmth, often leading to faster swim times. Ensure it allows for full range of motion in the shoulders.
• Goggles: Opt for comfortable, anti-fog goggles with appropriate tinting for the light conditions. Clear lenses for overcast days, mirrored or smoked for bright sun.
• Swim Cap: Brightly colored caps improve visibility. In colder water, two caps (one latex, one silicone) can add warmth.

Mental Preparation and Acclimatization

The mental aspect of open water swimming is as crucial as the physical.

• Desensitize to Conditions: Gradually expose yourself to the conditions you'll face: cold water, murky water, and crowded starts. The more familiar you are, the less anxiety you'll experience.
• Visualization: Before a race or challenging training swim, visualize yourself executing your plan perfectly, overcoming obstacles, and maintaining composure.
• Focus on the Process: During the swim, focus on your technique, your breathing, and your strategy rather than external distractions or anxieties. Break the swim into smaller, manageable segments.

By systematically addressing these aspects—refining your technique, mastering navigation, developing a strategic plan, training specifically, and preparing mentally—you can unlock significant improvements in your open water swimming speed and efficiency.
