Around the World on a Marathon Tour

With a cap on his head, a number tacked to his shirt, a book on tape occasionally blaring through his ears, Delbert Baker runs in some of the most historic places on earth.

He runs through the streets of Jerusalem, past the pyramids in Cairo, on the original marathon course in Athens, Greece.

At 55, he has run in so many famous sites that he now wants to see the rest of them. His goal is to enter marathons in every state and continent, even Antarctica.
