I have just done week 6 run 2 and I am amazed that I have made it this far. I am trying to lose weight and as I run on the treadmill at the gym I have been noting how many calories the treadmill says I have burned each run. It seems that the more time I spend running the fewer calories I am burning. Is that right? It seems unfair that I am covering more distance but using fewer calories. I assume there is a scientific explanation but I've got no clue what it is........help please.
