The Training Stress Score (TSS) quantifies the intensity and duration of a training session across various sports, including cycling, running, and swimming. It helps athletes understand their workload, optimize recovery, and plan training more effectively.
TSS is calculated using metrics like Functional Threshold Power (cycling), pace or heart rate (running), and average speed or intensity (swimming), combined with session duration. It provides a single number representing the overall training load. Higher TSS values indicate more demanding sessions and the need for longer recovery.
| Athlete | Sport | Typical TSS / Session |

| Chris Froome | Cycling | 120-200 |
| Tadej Pogačar | Cycling | 150-220 |
| Eliud Kipchoge | Running | 80-150 |
| Mo Farah | Running | 70-130 |
| Katie Ledecky | Swimming | 60-120 |
| Caeleb Dressel | Swimming | 50-110 |
