I am looking for a formula represented as an algorithm that will
calculate calories burned while running at variable speeds for people
of variable weight.

From the U.S. Army fitness manuals.

Running at 5 MPH burns .064 calories per minute per pound of body weight
Running at 6 MPH burns .079 calories per minute per pound of body weight
Running at 10 MPH burns .10 calories per minute per pound of body weight
Running at 12 MPH burns .13 calories per minute per pound of body weight

Hope this is useful.

Hello, runnfst,

I have summarized my research below:

Calculating a rate of calories burned per pound of body weight for
each of the plurality of running tests using a formula as follows:

Rate per Pound (Cal/lb-min)=A+BV+CV.sup.2 +KDV.sup.3 where: 

V=Running Speed (mph)--limited to a minimum of 3 mph and a maximum of 14 mph 

A=0.0395 

B=0.00327 

C=0.000455 

D=[0.00801(W/154).sup.0.425 ]/W 

W=Weight (lbs) 

K=0 or 1 (0=Treadmill; 1=Outdoors) 

and where A, B, C and D are known predetermined constants based on a
statistical sample of 2463 adults who run normally between 3 mph to 14
mph.
This is a United States Patent (6013009)- Walking/running heart rate
monitoring system. And there are also a formula that will calculate
calories burned while walking.

Here are other quotes that you may be interested in:

A running calories calculator which depends on variable weights and
running miles is found. And you can check up running calories
calculated by other formulae, however this is not a formula.

More on this question:

The approximate number of calories you expend by running a certain
distance can be found by taking 0.73 times your body weight in pounds
times the number of miles run. There are also formulae for swimming
and bicycling.

A runner friend of mine told me that you can calculate (very roughly)
the calories burned during a run by multiplying one?s weight in
Kilograms by the distance in Kilometers.

I hope this is helpful. If you have any questions regarding my answer,
or believe this is not the answer you want, please don?t
