Shouldnt the impact of elevation gain on weekly training metrics essentially negate the idea of one-size-fits-all training plans, or is it possible to accurately quantify and account for elevation gain across different routes and riders. Doesnt the very concept of Training Stress Score (TSS) become skewed when elevation gain is factored in, or is there a simple way to adjust TSS calculations to reflect the added stress of climbing. If elevation gain has such a significant impact on the bodys energy expenditure, shouldnt we be prioritizing elevation gain as a key metric in our training plans, rather than just focusing on accumulated distance or time. Are coaches and trainers doing their riders a disservice by not emphasizing elevation gain as a key component of training, or is there a nuanced approach that balances elevation gain with other metrics.
