I have mostly used Runkeeper to set running intervals and to report my pace and distance as I run. However I can see that it has a "target pace" as a goal whereby you tell it what pace you want to maintain and it tells you to "speed -up/slow down. I did try it once and thought at that time that it basically only told me what the distance/pace reports were already telling me.
However, now that I am running mostly non-stop runs , I am wondering if there is some advantage to using it in this format??
