Training Stress Score® (TSS) is a way of measuring how much stress is put on your body from a ride. TSS® is calculated using Normalized Power® (NP), Intensity Factor® (IF) and ride duration. TSS® helps to determine the best combination of workouts and rest periods.
Training Stress Score (TSS) can be used at both the athlete level (where typically used in conjunction with the performance manager chart) and the workout level. TSS can be expressed in chart or report formats.
