Beginner Triathlete to Ironman: The Swim


Listen Later

In this episode, Lou breaks her four-month silence to give a "no-filter" recap of her Ironman journey so far. Transitioning from a beginner to a long-distance triathlete is no joke, and while the swim might be the shortest leg of the race, it’s proving to be the biggest mental hurdle. Lou shares her ego-bruising lessons on technique, the tools she wish she’d used sooner, and the pre-pool anxiety that almost kept her on the couch.


  • The "Ironman Distance" reality check.

  • The Math of a Triathlon: Why the swim is often the forgotten discipline.

  • Lesson 1: Swallowing the ego and using swim tools (Paddles & Pull Buoys).

  • Lesson 2: Intervals vs. Distance – Why "just swimming" isn't enough.

  • Lesson 3: The Open Water Fear – Wetsuits, sighting, and toe-grabbing.

  • Lesson 4: The Mental Game – Overcoming pre-swim procrastination and finding "flow."

  • What’s coming up next (The Bike).

  • The Power of Tools: Don't let your ego stop you from using paddles (for hand positioning/catch) and pull buoys (for hip buoyancy). They are shortcuts to better form, not "cheating."

  • Structure Over Volume: Simply grinding out lengths is great for the soul but bad for the clock. Break sessions into intervals to maintain technique and build actual speed.

  • The "Blue Line" Trap: Pool swimming doesn't prepare you for the variables of open water. Practice sighting and getting comfortable in a wetsuit to avoid race-day surprises like chafing or shoulder fatigue.

  • The 60-Minute Mental Wall: Swimming is the ultimate "unplugged" sport. While the pre-swim anxiety is real, pushing through to find a flow state is where the magic happens.


"I’ve never known procrastination like it... but once I’m in the pool and I find flow state, it’s the most magical thing."
