Formula notes
The captured model combines a heart-rate fitness adjustment, grade coefficient, body weight, distance, and treadmill factor.
Worked examples
- Example: a 30-year-old runner weighing 75 kg and covering 10 km on a flat route gets an estimate near 756.945 kcal with the default settings.
- A 35-year-old runner weighing 70 kg and covering 5 km on a flat route gets an estimate near 351.9 kcal with the default settings.
How to use it
- Enter age, body weight, resting heart rate, and distance.
- Set the surface grade and treadmill option when relevant.
- Treat the result as an estimate and compare it with your activity context.
Frequently asked questions
Is this an exact measure of calories burned?
No. It is a formula-based estimate; fitness, pace, terrain, metabolism, and measurement quality can change actual energy use.
Can I use a negative grade for downhill running?
Yes, within the supported grade range. The result still remains an estimate rather than a medical or training prescription.
Limits and interpretation
- The result is a population-style estimate and can differ substantially from wearable readings or an individual's measured energy expenditure.
- Heart rate, grade, treadmill settings, and distance units must be entered consistently or the estimate can become misleading.
