Whats driving the trend in modern training plans to overcomplicate zone 2 work with complex interval structures, and is there any evidence to suggest that this approach yields better results than a more straightforward, traditional approach to building endurance?
Does the added complexity of modern zone 2 workouts, which often involve intricate interval patterns and precise pacing, truly enhance the physiological adaptations were trying to achieve in this zone, or is it simply a product of the current coaching and training culture?
In other words, are we overthinking zone 2 and neglecting the fact that, for many riders, the simplest approach - riding at a moderate pace for an extended period - remains one of the most effective ways to build endurance?
Are there specific rider populations or scenarios where a more complex zone 2 approach is warranted, or is this trend simply a case of coaches and trainers trying to justify their expertise by making the training process more complicated than it needs to be?
