What is easy pace in running?
Easy pace is a conversational effort where you can speak full sentences without gasping, typically 60-90 seconds per km slower than your 5K race pace. Heart rate sits in Zone 2, around 65-75% of your max. 70-80% of your weekly mileage should be at easy pace.
Easy pace is the foundation of every serious training plan, and it's almost always slower than runners think it should be. The correct easy pace feels almost embarrassingly slow — you should be able to hold a full conversation, breathe through your nose, and finish feeling refreshed rather than tired. In numbers: easy pace is typically 60-90 seconds per kilometer slower than your current 5K race pace. If you run 5K in 25 minutes (5:00/km), your easy pace is around 6:00-6:30/km. Heart rate zone: 65-75% of maximum, or roughly 140-155 bpm for most runners. The point of easy running isn't to get faster today — it's to build aerobic capacity, capillary density, and mitochondrial count without generating fatigue. Elite marathoners run 80% of their weekly volume at easy pace because the physiological adaptations from easy miles are different from (and complementary to) the ones you get from hard sessions. If your easy runs feel moderately hard, they're too fast. Slow them down — your Tuesday intervals and Sunday long run will be better for it.
