run 10 miles without stopping

I haven’t even gotten to five.. in fact, the most I’ve done is three, and that was half walking. But yesterday I walked fifteen miles—I was amazed at myself for not getting tired (I didn’t sit down and I just kept on going for eight hours!) .. it’s weird cuz when I run, my toes hurt. My foot’s shaped weirdly, I need to buy more comfortable shoes. My toenails are also weird, even though I clip them, they dig into my skin. It’s freaky and annoying.
