Setting the Stage

Hey everyone! If you caught my first post, you know I’m on a year-long mission to crush my first Ironman.

Over these next few months, I’m diving straight into Phase One (aka The Base Phase), where the goal is simple: build a super-strong aerobic engine, get comfy in the water, and avoid face-planting on the run.

If you want more details , check out classics like The Triathlete’s Training Bible by Joe Friel or Be Iron Fit by Don Fink — they’ll give you the science behind my approach.

Why Is a Base Phase So Important?

Think of the base phase like laying the foundation for your dream house. You can’t start picking wallpaper (or in this case, fancy carbon-fiber wheels) until the groundwork is solid.

By focusing on low-to-moderate intensity workouts, I’m aiming to:

  • Improve aerobic fitness without burning out.
  • Refine my technique in swimming, cycling, and running — because efficiency = fewer injuries.
  • Stay consistent — missing a week now could mess up the next few phases. Nobody wants that!

Big Picture Plan

Here’s my big-picture plan for the base phase, which runs for a few months:

  • Swimming: 2–3 sessions/week (30–45 min). Lots of drills and short intervals like 5×50 meters to keep me from turning into a lazy lap swimmer.
  • Cycling: 2–3 rides/week, starting at 1–2 hours, then pushing it to 2–3 hours by the end of March. Keeping the pace comfortable, because Going Long (Joe Friel & Gordon Byrn) says endurance is key!
  • Running: 3–4 runs/week (30–45 min). One long run builds up to around 75 minutes. This is straight out of the “long, slow distance” ethos you’ll see in Triathlete Magazine or on TrainingPeaks.com.
  • Strength Training: Twice a week, core and bodyweight workouts. Gotta keep that midsection strong for the miles ahead.

Weekly Schedule: The Nuts and Bolts

Here’s how I’m divvying up my days. Will I stick to this perfectly? Probably not. But hey, that’s life.

Monday

  • Bike: 1 hour
  • Lift Weights: Focus on upper/lower body strength and maybe sneak in some core.

Tuesday

  • Swim: 30 minutes (lots of technique drills!)
  • Run: 30 minutes (easy pace)

Wednesday

  • Bike: 1 hour (steady effort)
  • Lift Weights: Could be the same routine as Monday, or I’ll mix in different exercises if I’m feeling sore.

Thursday

  • Swim: 30 minutes; I have signed up for swimming lessons to perfect my technique
  • Run: 30 minutes (could be hill repeats if I’m feeling spicy)

Friday

  • Swim: 45 minutes (longest swim of the week — good time to practice endurance)

Saturday

  • Bike: 1–2 hours (easy pace now, but I’ll gradually push duration)
  • Run: 30 minutes (transitioning after the bike simulates a mini “brick” workout)

Sunday

  • Run: 75 minutes (this is my weekly long run — building that stamina!)
  • Core Exercises: Quick ab circuit, planks, maybe some yoga to stay limber.

Rolling with the Punches

Look, life happens and we need to listen to our bodies. I’m not gonna stress if I miss a session. We’re training for Ironman, not trying to break ourselves. So that’s the scoop on my base-phase plan! I’ll keep you posted on how it’s going, any tweaks I make, and whether I manage to cling to my sanity.

Until then, happy training !
