If You’re Training for an Ironman, Your Swim Might Be Missing This…

Why It Matters

Improving swim efficiency reduces fatigue and time loss, directly boosting overall Ironman performance.

Key Takeaways

• Prioritize upper-body pull over kick for Ironman swim efficiency.
• Use paddles and pull buoys to build sustainable propulsion power.
• Master sighting and drafting to save heart rate and time.
• Practice front-quadrant stroke; keep a hand forward before catch.
• Extend, rotate, then catch to avoid rushed, inefficient strokes.

Summary

The video teaches Ironman swimmers that speed alone isn’t enough; the focus should be on three core skills—upper-body propulsion, efficient timing, and strategic positioning.

Coach stresses pulling with the arms and torso while minimizing kick, using tools like paddles and pull buoys to develop sustainable power. He also highlights sighting and drafting: proper sighting prevents lost distance, and drafting behind a faster swimmer can cut heart rate by 10-20 beats and shave 5-10 seconds per 100 meters.

He cites examples of athletes who lost “hundreds of meters” by neglecting sighting, and others who gained time by drafting. He also points out a common flaw—rushing the catch—advocating a front-quadrant stroke where a hand stays forward, extending and rotating before the pull.

Adopting these techniques lets triathletes conserve energy, maintain lower heart rates, and improve overall race times, making the swim leg less of a bottleneck in Ironman competitions.
