Running Calorie Burn: What the Science Says
Running is one of the most calorically expensive activities per hour — a 160-lb person running at 6 mph burns approximately 600–650 calories in 60 minutes, comparable to vigorous swimming or rowing. The primary driver of calorie burn is body weight: the heavier you are, the more energy required to propel your body forward. Pace has a larger effect on calories per minute than per mile.
The "100 calories per mile" heuristic, popularized by Dr. Paul Williams at Lawrence Berkeley National Laboratory, holds remarkably well across a wide range of paces and individual sizes. While faster runners burn somewhat more per mile due to higher mechanical inefficiency at speed, the difference is small enough that distance is the primary predictor of total energy expenditure in running.
Excess post-exercise oxygen consumption (EPOC) adds a meaningful but often overestimated bonus to running's calorie equation. For moderate-paced runs, EPOC contributes an extra 5–10% over the following 1–2 hours. Hard interval sessions and very long runs produce greater EPOC — sometimes adding 50–100 extra calories post-session. This should be factored into total daily energy expenditure calculations on training days.
