Thanks for the reply but what I'm after is just a simple calculation of min/km.
example...
total run km = 2.48
total time = 12mins 23secs
therefore, my min/km = 12:23 / 2.48 = 4.93?
4.93 this is where I'm confusing myself. I am wanting to calculate in terms of time, I don't want 4(.93) - seconds go to 59 then turns into minutes. Holy cr@p am I confusing or what?!! I think basically, what I'm asking is what is 4.93 converted into mins and seconds?
