16-Week Olympic-Distance Triathlon Training Plan: A Complete Cycle from Base to Race Period

Introduction

Sprint triathlon requires simultaneous improvement in swimming, cycling, and running. A 16-week period is the most commonly used cycle length for amateur athletes, balancing training load with life stress. This article uses “8-12 hours of training per week” as the baseline and provides a complete periodization plan.

1. Four-Phase Allocation and Goals

2. Base Phase Weekly Schedule Example

The goal of the base phase is to build an aerobic foundation. All workouts are in the heart rate Z2 zone:

• Monday: Swim 1.5km technique drills + 30 minutes core
• Tuesday: Bike 60 minutes Z2 + 20 minutes run brick
• Wednesday: Run 8km Z2 + upper body strength
• Thursday: Swim 2km + Bike 60 minutes Z2
• Friday: Rest or yoga
• Saturday: Bike 2-3 hours LSD
• Sunday: Run 12-15km LSD

3. Key Build Phase Workouts

The build phase introduces threshold and VO2max workouts—the stage with the most noticeable improvement:

• Swim CSS: 6x200m @ CSS pace, 20 seconds rest
• Bike FTP: 4x8 minutes @ 95-100% FTP, 4 minutes rest
• Run threshold: 5x1km @ 10km race pace, 90 seconds rest
• Brick: Bike 90 minutes + immediately run 6km @ race pace

4. Taper Phase Considerations

Tapering is not stopping training; it is “reducing volume while maintaining quality”:

• Week 15: Reduce total volume by 30%, still maintain 1-2 intensity stimuli
• Week 16: Reduce total volume by 50%, completely rest or easy 20 minutes 3 days before the race
• Increase carbohydrate ratio in diet to 60-65%

Practical Advice

• Schedule a “recovery week” every 3-4 weeks, reducing total volume by 30-40%
• For office workers, it is recommended to do long rides on Saturday and long runs on Sunday, with swimming and short workouts during the week
• Strengthen open-water swimming and hill workouts 6 weeks before the Fulong race
• At least 1 brick session per week to build the muscle memory of running after cycling

Conclusion

The 16-week plan is not a rigid schedule but a framework to be adjusted according to individual weaknesses. It is recommended to execute it with a coach or training partner, and use TrainingPeaks or Strava to log weekly TSS and recovery status.
