Season, an AI coach that plans backward from race day

Field notes

Season describes a race-backward planning system that locks race week and taper before filling the calendar with build and base work. Its scoring model changes by session type: heart rate for easy days, power for hard days, and durability for long rides. The page also claims to derive FTP from two years of best efforts and calculate zones from raw samples, while naming Intervals.icu, Wahoo, and Hammerhead among its connected services.
