Winter is such a struggle for me! I, too, have my Winter fat storage on my belly - about 5 pounds. I'm hitting the big 5-0 next week, and found from this past year that 150 miles a week was the point where I could eat those treats once in a while, and not have it show, multiplied, on my body! 125 miles a week wouldn't do it, it had to be around 150. And I still can't eat just anything I want (darn it all) I always have to be conscious of what I eat to not be a little dumpling!

I'm sure that number will have to go up as my body continues to change, and my body gets used to the effort.
