Hi, I’m wondering if Race AI takes into account ‘endurance fatigue’ (or durability), or is purely driven by MPA / fitness signature? Eg if I have a long eg 1.5hr hard climb at 95% of threshold 3 hours into a race, will that be considered achievable (since it’s below threshold / not drawing down MPA), or not (because my ability to ride at 95% threshold is reduced over time (glycogen depletion etc).
I guess even if not explicitly taken into account, it may be implicit in the power file (assuming I find someone with similar fitness) I.e. they will probably also hold a lower % of threshold on that final climb too…? In that case, it’s another factor to consider when choosing the power profile
