Madonna's a lifelong runner

For someone who's in her 40s, has three kids and has been dominating the music industry since I was in elementary school, Madonna looks pretty good. Perhaps it's her strict macrobiotic diet. Perhaps it's her jam-packed schedule that is full of energetic performances around the world. Or perhaps it's that she's a runner and has been for ages, according to these photos on Fitsugar. The first photos are from 2007, and the second are from 1987 -- 20 years apart. The fashions have changed -- she's no longer sporting wrist bands, cheesy hats, a muscle T-shirt, a muletted blond running partner and 80s-style Reeboks, but the body looks the same, and not a lot of women who are nearing 50 can say that.

What do you think of Madonna? An inspiration for healthy living?
