What specific metrics or data points do professional cyclists use to determine the optimal duration and frequency of Zone 2 training sessions in their overall training plans, and how do these metrics vary depending on the individual riders goals, such as preparing for a grand tour versus a one-day classic?
Do pros prioritize Zone 2 training during the off-season, or do they focus on higher intensity intervals to maintain a level of fitness, and how does this approach impact their overall training structure?
How do coaches and trainers balance the need for Zone 2 endurance training with the risk of overreaching or burnout, particularly during periods of intense racing or competition?
What role does periodization play in incorporating Zone 2 training into a pro cyclists annual training plan, and how do coaches and trainers adjust the duration and intensity of Zone 2 sessions throughout the year to achieve specific physiological adaptations?
Are there any notable differences in how different types of professional cyclists, such as sprinters versus climbers, incorporate Zone 2 training into their plans, and what specific adaptations are they trying to achieve through this type of training?
How do advances in technology, such as power meters and GPS tracking, impact the way pros incorporate Zone 2 training into their plans, and what new insights or data points have been gained through the use of these tools?
