VELOARCHITECT

VO₂max Repeats is the supra-threshold lever Veloarchitect owns — 4×4 (Norwegian), 30/30, and 5×5 variants all belong here. Standard library prescriptions (TrainerRoad's Sweet Spot Base, Athletica's fixed-library VO₂max) fix the interval duration, intensity, and rep count in advance. Veloarchitect dispatches VO₂max Repeats against the Athlete's Failure Horizon projection: an Athlete with a 96-hour projection receives a 4×4 at 110% FTP; an Athlete with a 48-hour projection receives a 3×3 at 108% FTP; an Athlete with a 24-hour projection does not receive VO₂max work at all that week. ZWO→FIT Delta on the final interval is the per-session dispatch read. The dispatch is logged against the Athlete's 100-day True Normal so the longitudinal VO₂max Adaptation Rate — the velocity signal protocols read across weeks — confirms the supra-threshold block is producing adaptation rather than degradation.

Protocols: Protocol 11 — Failure Horizon; Protocol 10 — Adaptive Workout

The metric traverses the closed loop: Intent is the .zwo prescription the system computed against the Athlete’s True Normal. Telemetry is the .fit recording of the executed session. Adaptation is the longitudinal movement of the metric itself, logged against the True Normal and feeding back into the next day’s prescription via Protocol 10 (Adaptive Workout).
