Linear, reverse and block periodization: the differences
What training periodization is, how the linear, reverse and block models differ, and which one suits you.
Periodization means organising training into phases so that each one prepares the next. No model is better than the others: it depends on your experience, your calendar and your sport.
Linear periodization
It starts with high volume and low intensity, and gradually trades one for the other. It's the classic model and works very well for beginners or for anyone preparing a single race a year.
Reverse periodization
It starts with more intensity and less volume, and lengthens sessions as the race approaches. It suits very long events, such as a marathon or an ultra, where endurance is the last thing you need to sharpen.
Block periodization
It focuses on a few abilities during short blocks of two to four weeks: a threshold block, a VO2max block, a race-specific endurance block. It's useful for experienced athletes who need a strong stimulus to keep improving.
Which one to choose?
- If you're fairly new to training, linear is the safest.
- If your event is very long, try reverse.
- If you have years of base and have plateaued, concentrated blocks can give you the push.
Whatever the model, what matters is respecting recovery weeks and watching how your body responds.
