Intermediate Full Distance Progression

Moving beyond a standard finish requires a methodical approach to aerobic capacity and race-day durability. This 20-week plan provides a professional framework for intermediate athletes to improve speed and stamina. By following a science-informed structure, you replace the uncertainty of "junk miles" with purposeful sessions designed to fit around a demanding professional life.

The program prioritizes consistent, sustainable progression. We focus on building a resilient aerobic base before introducing race-specific intensity. This ensures you develop the necessary strength for the distance without the risk of overtraining, allowing you to arrive at the start line with the composure and fitness required for a strong performance.

The Benefits for You

• Front-Pack Preparation: Specific swim sessions tailored for athletes targeting the head of the field.


• Aerobic Durability: A logical build-up across all disciplines to ensure you can maintain intensity throughout the marathon.


• Time Efficiency: Achieve results with 6–8 purposeful sessions per week, maximizing your available training time.


• Strategic Taper: A controlled reduction in volume ensures you shed fatigue while maintaining the sharpness needed for race day.

The 20-Week Progression

• Block 1: Foundation. Establish baseline metrics and set training zones to ensure every session is performed at the correct intensity.


• Block 2: Adaptation. Systematic increase in session density to build structural and aerobic resilience.


• Block 3: Specificity. Peak volume phase including race-pace simulations to refine fueling and pacing strategy.


• Block 4: Taper. Strategic volume reduction to allow full recovery and ensure peak readiness for the event.

Is This Your Next Step?

• Intermediate Athletes: You can swim faster than 1:50/100m, cycle for 2 hours, and run for 90 minutes comfortably.


• Ambitious Competitors: You want a structured system that removes decision-making and focuses on performance outcomes.


• Busy Professionals: You need a manageable schedule that balances 6–8 sessions with 1–2 essential rest days.

The Deliverables

• 20 weeks of structured, progressive training: 2 Swims, 2 Bikes, 2 Runs, and 1 Strength session weekly.


• Open water efficiency focus for competitive front-pack swimming.


• Coach support via email for guidance on session adjustments or practical advice.


• Device Sync: Sessions load directly to your devices for real-time guidance.
