Would the physiological benefits associated with training in Zone 2 be more accessible to a wider range of cyclists if the individual could somehow travel back in time to the point at which they first started cycling, and apply the knowledge and experience theyve gained to that point in their progression?
In other words, if someone with 5-10 years of riding experience could go back and re-train from the start, using the knowledge of optimal training zones, equipment choices, and recovery techniques that theyve acquired over time, would this enable them to more easily attain and maintain the aerobic benefits of training in Zone 2?
Would this temporal advantage essentially allow the rider to shortcut the typical progression that occurs as one develops their aerobic endurance, or would other factors such as genetics, age, and lifestyle come into play and mitigate the benefits of this hypothetical time travel scenario?
