Erica Swensson claims that she's not a morning person, but three days a week she wakes up at 4:30 A.M. to do what she says is the most painful kind of endurance sport you can do- rowing. Why? Because it brings a sense of calm and peace. Because she lives for the beauty of the sunrise, the call of the morning birds and being on the water. And because the days when she doesn't row are just not as good.
