I'm guessing that you picked up this book because you are curious about becoming a runner. You've probably seen different types of 'Runner' out and about: in the gym, slogging away on the treadmill for hours at a time (how? - is a valid question); or on the streets pounding out the miles. You may even have wondered past an athletic track and seen people running in circles at various speeds from the gentle jog to lung-busters! If you have been really fortunate, you have watched from the side lines of a race. You have wondered, "Could I do that?", "Could I become a person who runs for fun/fitness/goals?" and "Am I a runner?"
