| Wednesday | Swim Tempo or Strength | 45–60 min |
| Thursday | Run Tempo or VO₂Max (build/peak) | 45–90 min |
| Friday | Bike Easy or Mix | 45–60 min |
| Saturday | Long Bike or Brick (Bike + Run) | 2–4 hours |

| Block | Volume | Focus |
|---|---|---|
| Base | 8-12 hrs | Aerobic foundation |
| Build | 10-14 hrs | Threshold work |
| Peak | 12-16 hrs | Race simulation |
| Taper | 6-8 hrs | Recovery & sharpness |
💡 Pro Tip: Each phase 3-4 weeks. 80% steady-state, 20% intensity. Recovery weeks cut 30-40%. Brick workouts (back-to-back sports) are critical.
Triathlon training planning is a periodized approach to multisport preparation. Rather than random workouts, effective plans follow structured phases: base (aerobic foundation), build (sport-specific power), peak (race-specific intensity), and taper (preparation for race day). Each phase has specific goals, intensities, and volume targets. Periodization prevents overtraining, optimizes adaptation, and delivers peak fitness when it matters most.
Why Periodization Works:
Most age-group triathletes benefit from 12–20 week macrocycles before goal races. Elite athletes often use 2–3 back-to-back macrocycles in a season.
Effective triathlon plans follow a structured macrocycle divided into four phases. Each phase has specific focus and intensity distribution.
Phase 1: Aerobic Base (30–35% of macrocycle)
Focus: Build aerobic capacity, technique, and movement quality
Intensity: 70–75% easy, 20–25% tempo, 5% high-intensity
Phase 2: Build (40–50% of macrocycle)
Focus: Develop lactate threshold, aerobic power, sport-specific skills
Intensity: 60–70% easy, 20–25% tempo, 10–15% high-intensity
Phase 3: Peak (20–25% of macrocycle)
Focus: Race-pace efforts, peak VO₂ max, anaerobic capacity
Intensity: 50–60% easy, 15–20% tempo, 20–30% high-intensity
Phase 4: Taper & Race (8–10% of macrocycle)
Focus: CNS recovery, maintain fitness, prepare mentally
Volume: 50% of peak phase; maintain intensity & skills
💡 Key Principle: Increase volume slowly (10% per week), prioritize consistency over perfection, and address your weak link (swim, bike, or run) with extra focus during build phase.
Scenario: Alex, an age-group triathlete, wants to race an Olympic-distance triathlon in 16 weeks. His current training volume is 12 hours/week, and his weak link is swimming (works on single-sport track). What does his training plan look like?
Alex's 16-Week Olympic Macrocycle:
Weeks 1–3: Base (3 weeks)
Volume: 8–10 hrs/week | Swim: 3 hrs (2 tech + 1 endurance), Bike: 4 hrs (easy), Run: 2 hrs (easy)
Weeks 4–9: Build (6 weeks)
Volume: 11–12 hrs/week | Swim: 4 hrs (3 tech + 1 threshold), Bike: 5 hrs (3 easy + 2 tempo), Run: 3 hrs (easy + 1 threshold)
Weeks 10–13: Peak (4 weeks)
Volume: 12–13 hrs/week | Swim: 5 hrs (3 tech + 2 VO₂ max), Bike: 5 hrs (2 easy + 2 VO₂ + 1 long), Run: 3 hrs (1 long + 2 VO₂)
Weeks 14–16: Taper (2 weeks) + Race
Volume: 6–8 hrs/week | Reduce volume 50%; maintain intensities. Week 16: Race day
Alex's Execution Strategy:
"I'll focus on swimming 5x/week in Base (technique priority) to close my weak link. During Build, I'll add threshold work in all three sports. Peak Phase brings race-pace intensities and longer efforts. Week 16: Taper completely, rest, visualize race, trust the training."
How many hours/week do I need to train?
Age-group (6–12 hrs), Advanced (12–20 hrs), Elite (20–30+ hrs). Start conservatively; increase 10% per week max to avoid injury.
Should I always follow a plan?
Yes. Even flexible plans prevent random efforts. Structure maximizes adaptation with less injury risk.
What if I miss a workout?
Don't panic. Miss one workout? Move on. Miss three in a week? Reassess recovery and stress management.
Can I train for multiple races in one season?
Yes, with separate macrocycles. Build to Sprint/Olympic, recover 2–3 weeks, train to Half-Iron. Elite athletes use 2–4 cycles/year.
How do I know if my plan is working?
Track weekly average pace/power trends, resting HR, and race-day performance. 2–4% fitness gains per macrocycle is normal.
Is it bad to train hard every day?
Terrible. Hard days stay hard; easy days stay easy (80/20 rule). Most training is aerobic; only 10–20% is high-intensity.
When should I address my weak link?
Base phase for technique, Build phase for volume + intensity. Don't neglect strong sports; maintain them while boosting weakness.
How long before I see results?
4–6 weeks for small gains; 10–12 weeks for significant improvements. One macrocycle = ~8% fitness gains with good adherence.
