As an experienced triathlete, you already understand that success at the Half Distance Triathlon level isn’t about doing more—it’s about doing what matters. Cozumel presents a deceptively fast course: warm, saltwater swim; flat, wind-prone bike; and a heat-exposed two-lap run. To perform at your peak, you need a training plan engineered for precision, not guesswork.

This 36-week Half Distance Triathlon Training Plan is designed for serious age-group athletes who value structured progression, physiological targeting, and purposeful volume.

🔍 Foundational First:
The plan begins with a 12-week base phase focused on aerobic efficiency and functional strength—laying the groundwork for high-performance adaptation later. You’ll develop resilience in all three disciplines before intensity ever ramps up.

📈 Smart Progression, Not Burnout:
Using a 3:1 periodization model, the plan balances overload with strategic recovery. Weekly volume begins at 9.5 hours and peaks at 14.5, scaling with the demands of Half Distance Triathlon performance—especially relevant in a heat-intensive venue like Cozumel.

⚙️ Swim Development with Intention:
Focused swim sets emphasize open water pacing, thermal adaptation, and form integrity under fatigue—essential for Cozumel’s warm, rolling-start swim.

💨 Bike Sessions Built for Output:
Expect intervals that simulate long flats with crosswind and headwind variability. You'll train to hold aero position under load—critical for navigating Cozumel’s 90KM loop efficiently.

🔥 Run-Specific Conditioning in the Heat:
Includes progressive long runs, tempo efforts, and pacing strategies that account for rising core temperature and hydration variables. This isn’t just about running—it’s about running smart when the heat peaks.

🧠 Advanced Energy System Development:

VO2 Max & Anaerobic Threshold Intervals

Power Sprint & ATP-PC Conditioning

Climbing Accelerations for strength-endurance carryover
Every workout has a physiological purpose tied directly to race-day execution.

📬 Includes direct email access to a coach—a sounding board for strategic adjustments, not generic answers.

🎯 If you're ready to approach your Half Distance Triathlon in Cozumel with a plan that respects your experience and challenges your limits, this is the training blueprint to get you there.
