VELOARCHITECT

TSS is the public-domain composite metric developed by TrainingPeaks; it combines intensity factor (IF) and duration into a single training-load number. Veloarchitect does not redefine TSS; it reads TSS against the Athlete's own True Normal. A 100 TSS session means different things to two Athletes with different True Normals. The Veloarchitect protocol tracks TSS-against-True-Normal weekly accumulation; a week of TSS accumulation 12% above True Normal is the early warning of Systemic Degradation Threshold approach.

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).
