(same goes for weight lifting)
since starting your 3 mile runs you will definitely raise your body's metabolism and if your not over eating you will lose some fat. our bodies are so very efficient, after a few of these runs your body will adjust to your 3 mile run and your body's metabolism spike will be shortened. after your body has adjusted to the run, metabolism will be heightened only for the duration of the 3 mile workout which is nothing compared to days on end of what it could be if intensity of the workout was greater and results at this point would not be apparent. if you decide to do sprints, you should make note of how long and how many sprints to make sure you are continuing to increase intensity. hope this helps
