Just a question about etiquette really - when you say "Yeah, I killed that 123K run" do you include the distance of the 5 minute warm up and warm down?
For more experienced runners I guess that distance is just noise but for the c25k crowd (at least for me) it is a non-trivial distance.
I do - I start my garmin activity before the 5 minute walk and stop it after the last 5 minute walk. The various web sites (garmin, strava etc.) clearly show the difference between the run and walk segments.
Dunno - I can't decide whether including it is 'cheating' somehow :-).
