Triathlon Half Ironman Intermediate 8 Weeks

Who is this L Triathlon training program for?

This plan is for intermediate triathletes, already initiated to the triple effort or regularly practicing one or two of the disciplines. It is for triathletes who wish to progress in L Triathlon distances with a structured, balanced, and performance-oriented plan with an average weekly volume of 4.4h. This program will allow you to consolidate your fundamentals, optimize your training time, and better manage your transitions.

✅ What you get with your plan:
🗓️ A structured week-by-week plan, balanced and demanding according to your level.
🏊🚴🏃 Varied sessions to develop endurance, technique, and speed.
🧠 Training blocks designed for measurable and sustainable progress.
🔁 Practical tips to optimize your recovery, nutrition, and equipment.
📱 PDF format + synchronization with Google Calendar.
🛠️ A plan developed by experienced coaches, tested and validated to reach a new milestone.

Weekly evolution of the training load and duration in the L Triathlon training plan

This graph illustrates the weekly distribution of the training load (according to the Edwards TRIMP method) and the total training duration (in minutes) over the entire plan. It highlights the gradual progression of loads, the overload and recovery phases, as well as the distribution of training volume over the different weeks. This visualization allows for tracking the evolution of the external load and ensuring compliance with the principles of progressiveness and periodization.

Why follow this l triathlon training plan?

• Structure your training by respecting the principles of progressiveness, intensity variation, and active recovery.
• Develop your qualities of resistance, speed, and ability to link disciplines without loss of efficiency.
• Strengthen your transitions (especially bike-run), which are often decisive.
• Integrate nutritional and mental preparation to approach the race with serenity.

• swimming sessions focused on technique, endurance, and open water adaptation,
• cycling sessions (road or home trainer) working on threshold, PMA, and cadence,
• running workouts (VMA, fartlek, endurance),
• brick sessions (bike + run) to optimize your transitions.
• GPP sessions to work on your muscular strength.
• Mental preparation sessions to optimize your potential.
• double training days from the intermediate level
• active rest: 1 to 3 days / week

Phases of the training program

A good triathlon training plan is based on structured progression. This l triathlon program is divided into three key phases, each with a specific objective and adapted content.
This allows for effective development of the necessary physical qualities, while optimizing recovery and final performance.

1. General strengthening phase (weeks 1 to 2)

This introductory phase aims to lay the foundations of the plan. The goal is to consolidate physiological basics while working on technique.

• Objective: improve fundamental endurance and strengthen the body.
• Content:
  • Easy runs,
  • Technical work in swimming,
  • Cadence drills on the bike,
  • General physical preparation (GPP) type muscle strengthening sessions.

  2. Specific development phase (weeks 3 to 6)

  This is the core of the program, where we seek to develop the specific qualities necessary for performance on race day.

  • Objective: raise physiological capacities (VO2max, threshold, running economy).
  • Content:
    • Intensive bike sessions: e.g., 3x10' at 85-90% of FTP,
    • Swimming sets at a specific pace (200 to 400 m),
    • Running: short VMA, tempo runs, or threshold pace,
    • Bike-run brick sessions to get the body used to the transition.
  • Weekly volume: on average 4.4h/week.

  3. Tapering phase (weeks 7 and 8)

  The last few weeks are dedicated to active recovery and performance optimization.

  • Objective: reduce the training load to allow the body to assimilate the work done.
  • Content:
    • Progressive decrease in volume,
    • Maintaining a light dose of intensity to keep good sensations,
    • Partial or shortened race simulation (without creating fatigue).

  This three-stage structure is used by the best coaches to maximize gains while avoiding overtraining. It allows you to arrive fresh, confident, and ready to give your best on race day.

  Weekly content and key tips

  Example of a typical week:
  
  • Swimming: 1 to 2 sessions – technique, endurance, strength, threshold...
  • Cycling / Home Trainer: 1 to 2 sessions – fundamental endurance, PMA, strength, velocity...
  • Running: 2 sessions – fundamental endurance, VMA, threshold...
  • Brick session: every 4 weeks from week 6
  • GPP / core training: 1 session on specific weeks
  • Mental preparation: 1 session on specific weeks
  • Double training days from the intermediate level
  • Active rest: 1 to 3 days / week
  
  Key tips:
  
  • Hydrate yourself during all sessions > 1h.
  • Plan for a carbohydrate intake 1h before intense sessions.
  • Alternate terrains (road, trails) to limit injuries.
  • Visualize transitions and repeat your automatisms in real conditions.
  • Go to bed at a fixed time: sleep is your primary recovery tool.
