Why Planning Matters More Than You Think
After 40+ years in triathlon—from my first race at age 13 in 1983 to still podiuming in age group competitions at 57—I've learned one truth that separates successful triathletes from those who plateau or burn out: a well-structured plan beats random training every single time.
Too many athletes jump straight into training without a roadmap. They swim when they feel like swimming, ride when the weather's nice, and run when guilt kicks in. Sound familiar? This approach might work for a few months, but it rarely leads to race-day success.
Step 1: Define Your "Why" and Set Clear Goals
Before you plan a single workout, answer these questions:
What's Your Primary Race?
- Race distance: Sprint, Olympic, 70.3, or Ironman?
- Race date: How many weeks do you have?
- Course profile: Hilly bike? Open water swim? Hot conditions?
What's Your Honest Starting Point?
- Current weekly training hours
- Strongest and weakest discipline
- Injury history or limitations
- Life commitments (work, family, travel)
What Does Success Look Like?
Be specific. "Finish strong" is vague. "Complete the bike in under 3 hours feeling good enough to run my best half marathon" is actionable.
Step 2: Understand the Building Blocks of Training
Every effective triathlon program balances three key elements:
Volume (How Much)
Total training time or distance per week. For most age-groupers:
- Sprint: 5-8 hours/week
- Olympic: 7-10 hours/week
- 70.3: 10-14 hours/week
- Ironman: 12-20+ hours/week
Intensity (How Hard)
Not all training should be hard. In fact, 80% of your training should be at easy, conversational pace. The remaining 20% includes threshold work, intervals, and race-pace efforts.
Frequency (How Often)
How many sessions per discipline per week. Minimum effective doses:
- Swim: 2-3x per week (technique-dependent sport)
- Bike: 2-3x per week (one long ride)
- Run: 3x per week (most injury-prone discipline)
Step 3: Map Out Your Training Phases
This is where periodisation comes in—the systematic planning of training into distinct phases.
Base Phase (40-50% of total plan)
Goal: Build aerobic foundation and movement efficiency
- High volume, low intensity
- Focus on technique in all three sports
- Strength training 2-3x per week
- Long, easy sessions to build endurance
Build Phase (30-40% of total plan)
Goal: Develop race-specific fitness
- Introduce intensity progressively
- Race-pace workouts
- Brick sessions (bike-to-run transitions)
- Reduce strength training to maintenance
Peak Phase (10-15% of total plan)
Goal: Sharpen fitness and simulate race conditions
- Highest intensity, controlled volume
- Race rehearsals
- Fine-tune nutrition and pacing strategies
- Mental preparation
Taper Phase (1-3 weeks)
Goal: Arrive at race day fresh and ready
- Reduce volume by 40-60%
- Maintain some intensity
- Extra sleep and recovery
- Trust your training
Step 4: Design Your Weekly Structure
A well-designed week follows a pattern. Here's a template that works for most age-groupers:
Monday: Recovery or Rest
Your body adapts during rest, not during training. Active recovery (easy swim, yoga) or complete rest.
Tuesday: Quality Session #1
Swim technique + some intensity, or run intervals. Fresh legs from Monday's rest.
Wednesday: Moderate Volume
Bike focus—either steady endurance or tempo work. Mid-week volume builder.
Thursday: Quality Session #2
Run or swim intensity. Second key session of the week.
Friday: Easy/Recovery
Short, easy sessions. Prepare for weekend volume.
Saturday: Long Session #1
Long bike or brick workout. The "bread and butter" of triathlon training.
Sunday: Long Session #2
Long run (if Saturday was bike) or long swim + easy bike. Complete the weekend volume block.
Step 5: Build In Recovery (Non-Negotiable)
The biggest mistake I see? Ambitious athletes who never rest.
Every 3-4 weeks, schedule a recovery week:
- Reduce volume by 30-40%
- Maintain some intensity (short efforts)
- Extra sleep
- Address any niggles with physio/massage
Recovery weeks aren't weakness—they're where adaptation happens.
Step 6: Track, Adjust, Repeat
Your plan isn't carved in stone. Use data to guide adjustments:
What to Monitor
- Training load: Are you progressing sustainably?
- Heart rate variability (HRV): Is your body recovering?
- Resting heart rate: Trending up = accumulated fatigue
- Sleep quality: The ultimate recovery metric
- Mood and motivation: Early warning signs of overtraining
When to Adjust
- Persistent fatigue lasting more than a few days
- Declining performance despite consistent training
- Elevated resting HR or suppressed HRV
- Life stress increases (work, family, illness)
Common Mistakes to Avoid
1. Too Much Too Soon
Increase weekly volume by no more than 10% per week. Patience prevents injury.
2. Ignoring Your Weakness
If swimming is your limiter, don't hide in the bike saddle. Address weaknesses head-on.
3. All Hard or All Easy
Polarised training works: easy days truly easy, hard days genuinely hard. The "moderate" middle zone is where progress goes to die.
4. Copying Someone Else's Plan
What works for a 25-year-old with no kids and flexible work hours won't work for a 50-year-old with family commitments. Your plan must fit YOUR life.
5. Neglecting Strength Training
Triathletes who strength train get injured less and perform better. Period. 2x per week in base phase, 1x in build/peak.
Putting It All Together
Here's a simplified example for an Olympic distance race 16 weeks out:
- Weeks 1-6 (Base): 7-8 hrs/week, easy aerobic work, technique focus, strength 2x/week
- Weeks 7-12 (Build): 8-10 hrs/week, introduce intervals, race-pace work, brick sessions
- Weeks 13-14 (Peak): 8-9 hrs/week, race simulations, fine-tune nutrition
- Weeks 15-16 (Taper): 5-6 hrs/week, reduce volume, maintain sharpness
