Open Water Swimming Skills

Introduction: Beyond the Black Line

Swimming in open water (lakes, rivers, oceans) presents unique challenges compared to the controlled environment of a swimming pool. Factors like navigation, variable water conditions (waves, chop, currents), close proximity to other swimmers, and lack of walls require specific skills and mental adaptation. Mastering open water swimming is crucial for triathlon success and safety.

Key Open Water Skills

  • 1. Sighting (Navigation)

    The most fundamental OWS skill – swimming straight!

    • Why: Buoys can be far apart, currents can push you off course. Swimming extra distance is inefficient.
    • Technique ("Alligator Eyes"): Lift your head *just* enough so your eyes clear the water, looking forward briefly to spot a landmark or buoy. Do this quickly and integrate it into your breathing pattern (often sight just before turning head to breathe) to minimize disruption to your stroke and body position. Avoid lifting your head too high, which causes hips/legs to drop.
    • Frequency: Sight every 6-10 strokes initially, adjusting based on conditions (more often in chop/currents) and proximity to buoys.
    • Landmarks: Use large, fixed objects on the shoreline (trees, buildings) beyond the buoy as reference points, as buoys themselves can be hard to spot, especially in waves.
    • Practice: Practice sighting regularly in the pool by looking at the end of the lane, and frequently during open water training sessions.

  • 2. Drafting

    Swimming behind or beside others to conserve energy.

    • Benefit: Can significantly reduce the effort required (up to 20-30%) by letting the lead swimmer break the water resistance.
    • Positions: Directly behind the feet (close but avoid constant tapping) or beside the hips (in the "bow wave").
    • Skills Required: Requires good awareness, ability to adjust pace slightly, and comfort swimming close to others. Bilateral breathing helps keep track of swimmers beside you. Sighting is still essential to ensure the person you're drafting is going the right way!
    • Practice: Practice swimming closely behind training partners of similar speed.

  • 3. Pack Swimming & Starts

    Navigating the initial chaos and swimming near others.

    • Mass Starts: Can be very physical (bumping, contact). Stay calm, protect your space, and don't panic if bumped. Seed yourself appropriately (faster swimmers front/center, nervous/slower swimmers back/sides).
    • Maintaining Composure: Practice swimming with others close by in training. Focus on your own stroke and breathing. Accidental contact happens; try not to react aggressively.
    • Finding Space: Look for pockets of clear water, especially after the initial sprint.

  • 4. Adapting to Conditions

    Handling waves, chop, currents, and temperature variations.

    • Chop/Waves: May need to adjust breathing timing (breathe away from oncoming waves), increase stroke rate slightly, and sight more frequently. A slightly higher, wider arm recovery might help clear choppy water.
    • Currents: Be aware of currents (check pre-race). Adjust sighting lines accordingly – aim slightly up-current of the buoy if crossing a current.
    • Temperature: Acclimatize gradually if possible. Use a wetsuit appropriate for the temperature (see Wetsuit Guide). Warm up properly before entering cold water.

  • 5. Buoy Turns

    Navigating crowded turn points efficiently.

    • Approach: Aim for the inside line if possible, but anticipate congestion. Sight frequently as you approach.
    • Execution: Maintain momentum. May need shorter, choppier strokes around the buoy. Protect your space but be courteous. Sight immediately after the turn to pick your new line.
    • Avoid Stopping: Try to maintain continuous movement around the buoy.

  • 6. Dolphin Diving / Wading (Entries & Exits)

    Efficiently moving through shallow water.

    • Entry: If shallow, run until water is ~knee/thigh deep, then perform a series of "dolphin dives" (dive forward, push off bottom, glide, repeat) until deep enough to swim properly.
    • Exit: Swim as far as possible until fingers touch the bottom. Stand up and run/high-knee through the remaining shallow water.

Safety Considerations

  • Never Swim Alone: Always swim with a buddy or group, or use a brightly colored tow float for visibility. Inform someone on shore of your plans.
  • Know the Conditions: Check water temperature, currents, weather forecast, and any local hazards before entering.
  • Be Visible: Wear a brightly colored swim cap (and tow float if swimming alone).
  • Acclimatize: Enter cold water gradually to avoid cold shock.
  • Know Your Limits: Don't attempt swims beyond your current ability or in conditions you aren't comfortable with.
  • Emergency Plan: Know how to signal for help (e.g., roll onto back, raise one arm).

Conclusion

Open water swimming requires adapting your pool skills and adding new ones like sighting and drafting. Consistent practice in open water conditions builds confidence and competence. Focus on staying calm, navigating effectively, and adapting to the dynamic environment. Prioritizing safety is paramount. With practice, you can become comfortable and efficient swimming beyond the black line of the pool.
