Pace to Calories Calculator

Turn your running, walking, hiking or treadmill pace into calories burned using the ACSM metabolic equations, with incline support.

Preparing a race: the pace a target time needs, the splits to hold it, and the training zones that sit under it — on foot, and equally on a bike or in a pool, where the same session is measured in watts or in a hundred-metre split instead.

Scaling a time linearly to a longer distance. A marathon is not two half-marathons; race predictors use an exponent around 1.06 precisely because fatigue is not proportional.

They sit next to each other but answer different questions: Calories burned calculator is the one to open when you need it to estimate calories burned during an activity (MET method). Pick whichever matches what you're starting from — both are free.

Pace Zone Calculator is the closest one after this: Turn your threshold pace into five training zones — recovery, easy, threshold, interval and repetition.

Triathlon Pace Calculator and Pace Converter — they come up in the same task often enough to be worth a second tab.

Pace arithmetic is exact. Race predictions follow Riegel's formula, which assumes training matched to the longer distance — without it the prediction is optimistic.
