TriTrainer Coach
Certified Triathlon Coach
Our programs are designed by certified coaches with over 10 years of triathlon experience. Each plan follows scientific periodization principles used by professional athletes.
Our Training Methodology
Our scientific approach ensures optimal progression while minimizing injury risk.
Block Periodization
Plan division into distinct phases (Base, Build, Peak, Taper) with specific goals for each. This structure enables systematic progression and optimal supercompensation.
Progressive Overload Principle
Gradual increase in volume and intensity by 5-10% per week, with recovery weeks integrated every 3-4 weeks to allow adaptation.
Training Specificity
Sessions are designed to replicate race demands: bike-run transitions, race nutrition, and mental fatigue management.
Individualization
Each program can be adjusted according to your availability, level and goals. Key sessions are identified to help you prioritize.
Prerequisites and Required Level
This program is designed for intermediate level triathletes. Here's what we expect before starting:
1-2 triathlons completed
Goal to improve time
Availability 6-10h/week

Nutrition and Hydration
A proper nutrition strategy is essential to optimize your performance and recovery.
Before training
Meal 2-3h before with complex carbohydrates. Regular hydration in the preceding hours. Avoid fiber and fats before intense sessions.
During training
For sessions >1h: 60-90g carbohydrates/hour. Hydration: 500-750ml/hour depending on conditions. Use gels, bars or energy drinks.
After training
Metabolic window: consume protein + carbs within 30-45 minutes. Optimal ratio: 3:1 carbs/protein. Rehydrate with 150% of weight lost.
Race day
Breakfast 3h before start. Nothing new! Only use products tested in training. Plan your nutrition stations.

Common Mistakes to Avoid
Avoid these frequent pitfalls that can compromise your preparation.
Neglecting recovery sessions
Solution: Recovery is as important as training. Respect rest days and deload weeks to allow adaptation.
Increasing volume too quickly
Solution: Follow the 10% rule: don't increase your volume by more than 10% per week to avoid overuse injuries.
Ignoring swim technique work
Solution: Technique in swimming represents 80% of performance. Dedicate time to drills and video analysis of your stroke.
Training too intensely
Solution: 80% of your sessions should be in Z2 (endurance). Intensity should be targeted and planned, not systematic.
Not testing race nutrition
Solution: Test your nutrition strategy during long sessions. Race day is not the time to try new products.
Neglecting brick sessions
Solution: Bike-run transitions are specific to triathlon. Practice them regularly to get your legs used to it.
Frequently Asked Questions
For intermediate level, we recommend 16 weeks of preparation. This timeframe allows you to progressively build your endurance, develop technical skills in all three disciplines, and reach peak fitness at the right time. A program that's too short may not allow necessary physiological adaptations, while one that's too long can lead to excessive fatigue or motivation loss.
This program requires between 6 and 10 hours of training per week, spread over 6 sessions. Volume evolves by phase: lower in base phase to build foundations, volume peak in build phase, then progressive reduction toward race day. Sessions are balanced between all three disciplines, with particular emphasis on your identified weaknesses.
This program is designed for triathletes who already have a training base. If you're completely new, we recommend starting with our beginner program which will help you build the necessary foundations. If you already have regular sports practice (swimming, cycling or running), you could adapt this program by reducing intensities in the first weeks.
Essential equipment: for swimming, quality swimsuit and goggles; for cycling, a road or triathlon bike in good condition with approved helmet; for running, shoes suited to your gait. To go further: neoprene wetsuit for open water, power or heart rate sensor, and GPS watch. Investment can be progressive - start with essentials and add equipment as you progress.
Fatigue is normal and part of the adaptation process. Our program includes recovery (deload) weeks every 3-4 weeks where volume is reduced by 30-40%. Listen to your body: temporary fatigue after a hard session is normal, persistent fatigue over several days requires rest. Prioritize sleep (7-9h), hydration, and balanced nutrition. Don't hesitate to skip a session if needed - it's better to arrive rested at a key session than fatigued at all of them.
Absolutely, flexibility is key. Each week identifies 2-3 key sessions (marked as priority) that should not be missed. Other sessions can be moved or reduced according to your constraints. If you must skip a session, prioritize keeping key sessions and rest days. You can also combine some short sessions or use an indoor trainer to save time on bike sessions.
Several indicators help measure your progress: regular tests (CSS in swimming, FTP cycling, threshold pace in running) are integrated into the program. Daily, monitor your resting HR in the morning (should decrease with training), your sensations during Z2 sessions (easier over time), and your times on reference routes. Keep a training journal to note your sensations and identify trends.
Nutrition is the fourth pillar of triathlon. Daily: prioritize complex carbohydrates, quality proteins, and plenty of fruits/vegetables. Before training: meal 2-3h before with carbs. During (sessions >1h): 60-90g carbs/hour + hydration. After: 30-45min metabolic window for protein + carbs. On race day: nothing new! Test your nutrition strategy during long training sessions.
Bricks are essential in triathlon as they prepare your body (and mind) for the bike-run transition. The "heavy legs" sensation after cycling diminishes with practice. Our program includes at least one brick per week. Start with short transitions (30min bike + 15min run) and increase progressively. These sessions also allow you to test your nutrition and equipment in real conditions.
Pre-race stress is normal and can even improve performance. Our taper phase includes mental preparation elements: race visualization, strategy review, equipment checklist. Practical tips: arrive the day before if possible, course reconnaissance, tested wake-up and breakfast routine. On race day: focus on your plan, not others. Every triathlon is a learning experience.
Simple rules: symptoms above the neck (mild cold) = light training possible. Symptoms below (fever, body aches) = complete rest. For injuries: consult a professional, don't push through. A few days off has little impact on fitness. The program can be adjusted: shorten a phase, skip a build week, but keep the taper intact. Better to arrive slightly less prepared but healthy than risk worsening an injury.
Times vary based on level and course. For olympic: beginners aim for 3h-3h30, intermediate 2h20-3h, advanced Under 2h20. These times are indicative - your first goal should be to finish and enjoy the experience. Times will come with experience and subsequent races.
