In the following table, you can find more information on how to interpret the pain score:
RPE, or Rating of Perceived Exertion, is a simple yet powerful way to measure how hard a runner feels they worked during a session. It provides valuable subjective insight that complements objective data like distance, speed, and mechanical load. In the OnTracx app, we capture RPE after each running session to better understand an athlete's internal response to their training. By tracking RPE over time, we can identify patterns in fatigue, assess training intensity, and ensure that load progression aligns with the perceived intensity.
