Triathlon training is a juggling act—three disciplines, limited time, and the constant challenge of balancing swim, bike, and run fitness without overtraining. The best triathlon plans use block periodization to emphasize one discipline at a time while maintaining the others.
For sprint and Olympic distance, 12–16 weeks of structured training is typical. For 70.3 and full Ironman, 20–30 weeks provides the volume progression needed. Each week should include at least 2 sessions per discipline, with the dominant discipline getting 3–4 sessions during its focus block.
Brick workouts—bike immediately followed by a run—are essential for triathlon-specific fitness. They teach your legs to run on fatigued muscles and help calibrate pacing for race day. Include at least one brick per week in the build and peak phases.
Swim training often gets neglected, but it’s where the most time can be gained per hour of practice, especially for beginners. Focus on technique drills, open water practice, and threshold sets. Bike training should include both endurance rides and threshold intervals. Run training follows similar principles to standalone running plans but with reduced volume to account for the other disciplines.
Transition practice matters more than most athletes realize. Set up T1 and T2 simulations in training to build automatic habits.
