30 minutes of
running downhill

331 kcal 30 minutes of running downhill burns approximately 331 calories for a 70 kg adult, based on a MET value of 9. Heavier bodies burn proportionally more: 425 kcal at 90 kg, 520 kcal at 110 kg.

How this is worked out

  1. Take the MET value for running downhill from the 2024 Adult Compendium of Physical Activities: MET 9, the median of its 5 measured variations (MET 5.8–13.8).
  2. Convert MET to a rate using the ACSM relationship: multiply by 3.5, then by body mass in kilograms, then divide by 200. That gives kilocalories per minute.
  3. Multiply the rate by the number of minutes actually spent.
  4. Round to whole kilocalories. Nothing else is applied — no age factor, no sex factor, no proprietary adjustment, because the underlying data does not support one.
kcal/min = MET × 3.5 × mass(kg) ÷ 200
kcal     = kcal/min × minutes

9 × 3.5 × 70 ÷ 200 = 11.03 kcal/min
11.03 × 30 min       = 331 kcal

Questions

How many calories does 30 minutes of running downhill burn?

About 331 kcal for a 70 kg adult at MET 9. At 60 kg it is 284 kcal and at 100 kg it is 473 kcal.

Is 30 minutes of running downhill a good workout?

At MET 9 this is very vigorous activity. Adults are advised to accumulate 150 minutes of moderate or 75 minutes of vigorous activity a week, so 30 minutes is 40% of a week's target at that intensity.
