Your pace for the same HR is going to increase simply from the conditioning at that HR even if you lost zero kg - this is the principle behind the Maffetone Method.
To get a better idea, plug your current numbers into http://fellrnr.com/wiki/VDOT_Calculator and include your weight - it will give you predicted times if you lost Xkg. Enjoy your eating disorder!

True, but that improvement will be finite and trend towards some final value. Whilst overweight I'm going to see much better gains from losing weight.

Thanks, that's very useful and the figures make sense to me, and it's probably more useful than individual anecdotes. Given my current 5k times if I get to my target weight it suggests a sub 4h marathon so I'm happy with that (as a sugestion purely based on a 5k time and a weight!)

there is a lot of numbers on that fellrnr page.
does anyone have time to actually look at that, work out appropriate runs and then complete them all?
much easier just to run some runs fast, some long ones slow and do a track session once a week. and eat sensibly, not the 3 snickers I had after pasta for lunch yesterday.
Anyone got example (anec)data from losing weight and the effect it had on your running?
Right now I can run at a steady 10.5kph (5.40min/km) along the flat and my HR will sit around a comfortable 160bpm. This is me at ~88kg, I'm 5'8" so this is quite overweight. I'm on my way down to 76kg (and ideally 70kg but I will start with getting back to a BMI of 'Normal').
It's obvious that as the weight comes off my HR should be lower for the same workout (all other things being equal; weather, health, etc) but I know it's more likely that I'll end up running to the same perceived effort and going faster for the same or even slightly increased HR. (It doesn't get easier, you just get faster.)
I'm just looking for someone who's got HRM/GPS data from a time when they lost loads of weight who can say: "I used to do x min/km at y bpm and after losing z kg I can now do blah blah blah."
