    Hello everyone,

    I am looking for a little advice. I have been working out on my norditrack treadmill for almost 3 months now. I do the walk/jog routine. I will usually walk for 3 min. at 4.0 then jog for 3 min at 5.0 (I am new to running and this is what I can comfortable tolerate at this point) I do this routine for 30-45 min a day. My questions:

    1)When I log my training on map my run. It doesn't give me the option of cardio-treadmill under the walking category, so I log it under gym, then cardio treadmill, is that okay? 

    2)After my workout,the treadmill, my heart rate monitor and map my run never corelate on my calories burned. For example: after 45 min on the treadmill, my distance was 3.27 miles. The treamill reads 270 calories burned, the heart rate monitor reads 189 calories burned and map my run says 421 calories burned. I am so confused. Which should I go by?

    Thank you.

    Have a look at this: http://marathondan.blogspot.com/2004/11/calories.html

    Try and calculate it for yourself (based on distance and weight) and then compare. Pace doesn't seem to have much effect.

    I've been wondering about this too, so thanks for the link. If the equation really is...

    Running at 70% of maximum heart rate, calories burned per mile = 0.73 * body weight in lbs.

    ...then the only variables in calculating calories burned are MaxHeartRate, ActualHeartRate, and Weight.

    If that is true, I gotta believe your heart rate monitor should be the best measure of calorie count because it can calculate it over the course of your workout as your heart rate varies. Provided you you have set up the monitor to know your correct body weight and max heart rate, which means you need to have a proper measure of max heart rate (not the typically quoted 220 - your age).

    BTW, this would also mean that the calories from the MapMyRun calculations are bogus, since it does not use the heart rate information entered on Step 2.
