Whats the point of Zwifts adaptive training plans if theyre just going to be based on arbitrary FTP numbers and not take into account the actual physiological demands of real-world riding, and how can we trust the plans to deliver meaningful gains when theyre so heavily reliant on a single, potentially flawed metric, and isnt it time for Zwift to move beyond the simplistic FTP-based model and incorporate more nuanced and sophisticated measures of rider fitness and performance, such as lactate threshold and aerobic capacity, and wouldnt that provide a more complete and accurate picture of a riders abilities and needs, and ultimately lead to more effective and targeted training plans.
