Power vs Heart Rate vs RPE: Which Metric is Best?
OVERVIEWPower, heart rate, or RPE (rate of perceived exertion or how you feel)? Which data point is best for gauging intensity during training or a race, and which is best for monitoring training progress? Coach Adam Pulford tackles these frequently asked questions in Episode 249 of "The Time-Crunched Cyclist Podcast". Although ALL THREE metrics have their place, Coach Adam reveals the hierarchy for what matters most and what metrics are used for context. TOPICS COVEREDPower vs Heart Rate vs RPE HierarchyHow to keep HR from drifting up during intervalsWhy HR might drop during intervalsWhy prioritize Power first, then RPE, and HR lastTraining at the top vs bottom of power zonesAll about Rate of Perceived Effort (RPE)Why three data points are better than oneASK A QUESTION FOR A FUTURE PODCASTLINKS/RESOURCESEston, R., & Connolly, D.
