If i jog at my default pace (which i can comfortably sustain for a long time) i'm around 7 min/km.
Pushing myself some more and remembering to go faster and not drop to my default pace i'm at about 6:30 min/km.
I run with an app (sportractive) on my smartphone which tracks my runs and also tells me my distance, pace and time
every 0.5km. So if i would aim for a certain pace i only get an update after 0.5km in the worst case.
I know that there a running watches which show you the pace (and update it constantly?).
Is there any simple way to figure out the current pace?
