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.How about: go run a mile at 5K pace. The next day (or when recovered) put on a 10 pound weight belt and run the same mile at the same effort and HR. Subtract 3.1 times the difference. Should be in the ballpark; better than a total guess, anyway....
