I'm not sure I agree with either Dan or Steve on this one. So here is some more fuel for the debate: Surely jogging and running have to do with your pace, and not your objectives? So I may be starting to run longer and faster than I did previously (given that I started at 1 min run/1 min walk 3 months ago, and am now running solidly for 30 minutes - and I use the word "running" here loosely), but I still think I am a jogger and not a runner. Relative to 3 months ago though I am running both longer and faster, and that is my overall objective. But my pace still feels slow for now, and I know that my foot falls do not make me look like a runner.
Also, for those of you that consider yourself runners: what do you do on your long, slow distance workouts that you typically do on Sundays? Are you running or jogging? Also, marathon runners, who have to stay the whole distance - and ok, this maybe applies to those that take over 4 hours - do they run or jog?
So I think running or jogging has to do with pace per workout, and I'm interested to see BUPA's threshold limit of 7 minute/mile pace mentioned by Bagpuss. To me, that's a pretty tough threshold.
