I have seen various figures thrown around and while I know it varies from person to person, what on average would you say would be time saved in a 5K vs. lbs lost.
If I was to guess for myself, at 180 lbs or so, if I lost 10 pounds and still kept my strength and endurance, it would maybe equate to 45 seconds?????? this is a total guess. Thoughts? Studies would be great if you can show me a link to them.

Just found this...not sure how legit it is.In terms of running, smaller is usually better. Packing extra body fat on your frame will slow you down. In his book, “Serious Runner’s Handbook”, running expert Tom Osler suggests that every pound of excess weight will decrease your running performance by 2 seconds per mile. So, if you add 10 pounds of unwanted body fat you will lose 20 seconds per mile from your running pace. There is little scientific evidence to back up that claim, but in both my personal and coaching experience I have found that number to be fairly accurate. Of course, that will vary from person to person, but there is no question that excess body fat weight will slow you down.
