The first mile is mental. The rest are all heart.

I've been barefoot most of my life: either flip flops or barefoot on the pool deck. Although you'd think that would make me a good candidate for barefoot running, that doesn't work with me.

When I was training for the Olympics, I didn't eat the way I should have. I missed out on much-needed protein and opted for every easy carb.
