That you might be fighting the elements, competing against the clock or other athletes - but in the end the hardest opponent you’ll ever face is yourself. This story is told through the eyes of a female runner who accepts that challenge, looks herself in the eye and understands that the only race she’ll ever be in is the one against herself.
