The biggest difference between successful triathletes and those who struggle isn't talent or time—it's structure. A well-designed training week balances stress and recovery, develops all three sports, and fits into your real life. Here's how to build a weekly training structure that works.
📅 What You'll Learn in This Guide
- The anatomy of a balanced training week
- How to sequence different types of training
- Sample weekly structures for different experience levels
- How to adjust your plan when life gets complicated
The Principles of Weekly Structure
Principle 1: Hard Days Hard, Easy Days Easy
Why it matters: Mixed-intensity days lead to chronic fatigue without adaptation
How to apply: Cluster your intensity, separate your recovery
Principle 2: Complementary Training
Why it matters: Smart session sequencing enhances rather than interferes with adaptation
How to apply: Follow hard bike days with easy swim days, not hard run days
Principle 3: Progressive Loading
Why it matters: Your body adapts to gradual increases in training stress
How to apply: Increase total weekly load by 10% every 3-4 weeks
Principle 4: Recovery Integration
Why it matters: Adaptation happens during recovery, not during training
How to apply: Schedule recovery as intentionally as you schedule workouts

- Recovery between hard days
Friday: Swim Key Session
- 75-90 minutes
- Race-pace work and speed
- Primary swim development day
Saturday: Long Training Day
- 4-6 hour bike ride
- OR 2-3 hour bike + 1 hour run brick

- OR complete rest if Saturday was a brick
- Endurance development
Weekly Totals:

- Bike: 7-9 hours
- Run: 4-6 hours
- Strength: 2-3 hours
Sequencing Training for Maximum Benefit
High-Intensity Day Sequencing
Option 1: Back-to-Back Hard Days
- Tuesday: Bike intervals
- Wednesday: Run intervals
- Advantage: Consolidated stress, longer recovery periods
Option 2: Alternating Hard Days
- Tuesday: Bike intervals
- Thursday: Run intervals
- Saturday: Swim intervals
- Advantage: Better recovery between sessions
Sport-Specific Considerations
Swimming after cycling:
- Easy swimming helps with active recovery
- Technique focus when legs are tired
- Good combination
Running after cycling:
- Brick training effect
- Specific to triathlon demands
- Requires careful progression
Cycling after running:
- Generally well-tolerated
- Less impact stress
- Good for active recovery
Adjusting for Your Schedule
Time-Constrained Athletes
Strategies:
- Double sessions (swim + strength)
- High-intensity focus (less volume, more intensity)
- Efficient brick sessions
Sample adjustment:
- Tuesday: 45 min bike intervals + 20 min run
- Thursday: 45 min swim + 30 min strength
- Weekend: One long session only
Busy Weekday Schedule
Strategies:
- Move intensity to weekends
- Use lunch breaks for short sessions
- Early morning or evening slots
Sample adjustment:
- Weekdays: 30-45 min easy sessions
- Saturday: Long session with intervals
- Sunday: Second sport long session
Travel/Irregular Schedule
Strategies:
- Flexible session timing
- Bodyweight strength routines
- Pool/gym finder apps
Sample adjustment:
- Maintain weekly totals
- Adjust daily distribution as needed
- Prioritize key sessions
Common Weekly Structure Mistakes
Mistake #1: Every Day Is Medium-Hard
The problem: Chronic fatigue without adaptation
The fix: Polarize your intensity—hard days hard, easy days easy
Mistake #2: Random Session Sequencing
The problem: Poor recovery, interference between sessions
The fix: Plan session sequence to enhance recovery
Mistake #3: Ignoring Life Stress
The problem: Training stress + life stress = overload
The fix: Adjust training based on total stress load
Mistake #4: No Flexibility
The problem: Rigid plans break when life happens
The fix: Build flexibility into your structure
Mistake #5: Skipping Recovery Sessions
The problem: Missing the "easy" in easy days
The fix: Make recovery sessions non-negotiable
Your Weekly Structure Action Plan
✅ Week 1: Choose a structure that matches your time and experience
✅ Week 2: Test the structure and note what works/doesn't work
✅ Week 3: Make small adjustments based on recovery and performance
✅ Week 4: Implement a recovery week (reduce volume by 30-40%)
✅ Ongoing: Evaluate and adjust monthly
Fine-Tuning Your Structure
Monthly Evaluation Questions
- Am I recovering adequately between hard sessions?
- Are my long sessions feeling sustainable?
- Is my weekly structure realistic for my lifestyle?
- Am I seeing progress in all three sports?
Signs You Need to Adjust
- Consistently tired despite adequate sleep
- Declining performance in key sessions
- Dreading training sessions
- Frequent minor injuries
