I think a heart rate is all you are mssing. I am not talking about a measure of exertion in a particular activity. This can have a small effect on calories burned. I am talking about as a proxy for ones physical condition. Now this can make a difference. When I first started, my calories expended was high, because of my physical shape. Now I burn much less calories on the same exercise. Also, it is nice to keep your heart rate up for a good cardio exercise.

By the way, what is the difference between Strava and MapMyFitness? Strava supports segements, and interfaces well with my watch. However, for MapMyFitness, I think all you need is a phone and a step counter, and your step counter can also be your phone. It looks like it even interfaces with the sensors themselves without the watch. Interesting. This is another instance of not needing a watch. They both also support routes.

I have made 4,823 steps. I walked more than a mile at a casual pace. However, I went to a track and walked/ran for a 3/4 of a mile. So I burned 76 calories not including those slow walks. This makes for a target of 2,416 calories. By the end of the day, I will have consumed 2,432 calories. On one circuit of the track, I averaged a speed of 4.8 mph with an average hearbeat of 151 bpm. Now my leg is sore again. So I am going to skip exercise for tomorrow. I just cannot help keeping myself from walking. I think I am addicted. Better than illicit drugs.
