About Training Load and ACWR
Training Load is estimated per run as duration (minutes) times how it felt (1-5), a simplified session-RPE model. Acute:Chronic Workload Ratio (ACWR) compares your last 7 days of load to your trailing 28-day average. Values roughly between 0.8 and 1.3 are considered a stable training zone; higher ratios are associated with increased injury risk in sports science literature, most often from ramping mileage or intensity up too quickly.
