How many calories burned running 8km?
Well, without information on your expected heart rate during your run, this calculation will only give you a base amount of calories burnt during your run. I’ll break the calculation down into steps: 1. Convert your weight in lbs to kg 98lbs / (2.2 lbs/kg) = 44.545 kg 2. Calculate your weight force in Newtons 44.545 kg * 9.8 m/s^2 = 436.541 N 3. Multiply your weight force by the distance traveled to obtain base work performed 436.541 N * 8000 m = 3492328 J 4. Convert base work into calories 3492328 J / (4184 J/Calorie) = 834.686 Calories You will burn at least 835 Calories during this 8 km run. Again, since your heart rate is not supplied, this calculation is only a base calculation. This is, in my opinion, a safe pace for such a long length. The pace is somewhat competitive but it is also healthy. (Note: I am not a doctor, I am simply a student who loves to calculate) Good luck with your fitness!
