Training Principles
By Coach Brett Petersen

In this edition of training principles, triathlon coach Brett Petersen explains some of the more common mistakes that occur during the fall and winter between the race seasons. These mistakes are:
1. Not taking downtime between race seasons
2. Neglecting weight training
3. Focusing on distance vs. speed training
4. Not focusing on the limiter

In this issue of training principles, I will review the research that provides validity in training by heart rate. I will also discuss the advantages and disadvantages of training by heart rate. Finally, I will review current research that provides evidence for training by heart rate during long endurance training sessions, versus training by power or pace.

The three determinates of endurance performance are VO2 max, lactate threshold, and economy. While training, many athletes correctly work to improve their lactate threshold and VO2 max, but unfortunately neglect economy. This is unfortunate because this is what truly separates fast age-group athletes from the elite.
