See, I'd call that a progressive run. <img alt="smile.gif" src="http://files.kickrunners.com/smilies/smile.gif"> I guess it's all in the context and what program you're following.<br><br>
The point I was trying to make, or caution about, is that some runners, newer runners especially, can get caught up in trying to speed up their runs as they go along, thinking if they finish faster that's always a good thing. That's counter-productive for most training runs. After a warm-up, a training run should be run at the pace the run is intended to contribute to the training -- general aerobic, tempo, easy, recovery, etc. (which is why I don't time most of my runs and run by feel).
