Should I adjust zone 2 training for different temperatures, or is it just a myth perpetuated by coaches who want to make training more complicated than it needs to be? Ive heard some argue that temperature affects heart rate and perceived exertion, so zone 2 should be adjusted accordingly, while others claim its negligible and only matters for extremely hot or cold conditions.
But whats the actual science behind this? Is it just a matter of personal preference, or are there concrete benefits to adjusting zone 2 based on temperature? And if so, how should I be adjusting it? Should I be using a specific formula or guideline, or is it more of a listen to your body kind of thing?
Ive also seen some coaches recommend using a temperature correction factor to adjust zone 2, but Ive yet to find a consensus on what this factor should be. Some say its as simple as adding or subtracting 1-2 beats per minute for every 10 degrees of temperature change, while others claim its much more complicated.
So, whats the verdict? Should I be adjusting my zone 2 training for different temperatures, or is it just a waste of time? And if I should be adjusting it, how should I be doing it?
