Running metabolic-power estimator
This tool estimates gross metabolic power from body mass, pace and slope using a published running-energy-cost model. It is an energy scenario, not the mechanical power reported by Garmin, COROS or a footpod. Do not copy the result into device power zones. The distinction matters more than the number of displayed watts.

Why this number?
Metabolic watts ≈ Minetti running cost in J/kg/m × kg × m/sec. This is not a wearable power algorithm.
How do I use it?
- Enter recent, representative values.
- Choose units and check the assumptions.
- Review the result and its context.
- Copy, share or print the output.

Questions, answered.
What does a running-energy model estimate?
This tool estimates gross metabolic power from body mass, pace and slope using a published running-energy-cost model. It is an energy scenario, not the mechanical power reported by Garmin, COROS or a footpod. Do not copy the result into device power zones. The distinction matters more than the number of displayed watts.
Is this the power shown by Garmin, COROS or Stryd?
No. It estimates gross metabolic cost with Minetti’s model. Device running-power methods are different.
Can I use it to set watch power zones?
No. A metabolic estimate should not be substituted for a device-specific mechanical power reference.
What does the result assume?
Metabolic watts ≈ Minetti running cost in J/kg/m × kg × m/sec. This is not a wearable power algorithm.
Is this an exact prediction?
Arithmetic conversions are exact within input precision. Physiology models and planning scenarios are estimates; use the assumptions and your training response.
Can I change units or share this result?
Yes. Unit preference is remembered on this device. The share link includes calculator inputs; review them before sharing.
Do I need an email address?
No. Results, methodology and printable output are available without an email wall.
