Building Open-Water Confidence

By James Calder

For many triathletes the swim is the most nerve-wracking part of race day. There are no lane ropes, no black line to follow, and a few hundred other people doing their best to swim over you. The good news: open-water confidence is a set of learnable skills, not a personality trait.

Sighting without losing rhythm

The black line does your steering in the pool. Outdoors, you do it yourself.

  • Lift your eyes — not your whole head — just enough to glimpse the buoy.
  • Sight every 6–10 strokes, combining it smoothly with your breath.
  • Pick a big landmark beyond the buoy; buoys disappear behind chop.

Managing the start

The mass start is chaos by design. Take the sting out of it:

  1. Position yourself honestly. Confident swimmers to the front, everyone else to the side to find clear water.
  2. Start controlled. Going out too hard spikes your heart rate and triggers panic. Settle into rhythm in the first two minutes.
  3. Have a reset. If you feel overwhelmed, roll onto your back, breathe, and carry on. It costs seconds and saves your race.

Calm is fast. Most time lost in open water comes from tension and poor navigation, not a lack of fitness.

Drafting — free speed

Sitting on another swimmer's feet or hip can save 5–10% of your energy. Find a pair of feet moving at your pace, settle just behind them, and let them break the water for you. It's one of the few entirely legal "gains" in triathlon.

Practise the specifics

Pool fitness doesn't automatically transfer. Spend time in open water before race day — even a handful of sessions to rehearse sighting, starts and swimming close to others will transform how race morning feels. Our triathlon coaching builds these skills into your plan well before you toe the line.
