I'm 77kg/170lbs and my daily run is 16km/10mi with a little bit of climbing. My 735XT tells me my runs burn 700-800 calories and the numbers have been more or less consistent in the past half year. Although it's a very rough estimate, the numbers seem too low. I'd expect someone at my size would burn at least 100 calories per mile. In fact, it used to be 100-120 last year. I'm not sure what happened. I did switch from imperial units to metric some time ago though.
