Ironman swim training is widely misunderstood. Many age-group triathletes assume they need more swim volume or harder swim sets, when what they really need is better, more efficient swimming that sets up the rest of the race.

In this episode, we break down the five factors that matter most for Ironman swim performance, especially for time-crunched athletes balancing training with work and life. We talk about why the Ironman swim is not a fitness test, why economy and calm matter more than raw speed, and how poor swimming quietly sabotages bike power and run durability later in the race.

You’ll learn why swim frequency often beats swim volume, how to make technique work actually transfer to racing, and which open-water skills meaningfully reduce energy cost on race day. We also discuss how swim training should be integrated with bike and run training, rather than treated as a separate performance goal.

This episode is about leverage. If you want to exit the water composed, preserve energy, and start the bike in control, this is the swim training framework that actually works for Ironman racing.
