The best way to know where you’re going with your training is to see where you’ve been. Keeping a personal journal of your runs helps you track your progress, avoid past pitfalls and even inspire you to new accomplishments. Your journal can be as simple as a few dashed notes of the distance and time you ran each day, or more detailed with lengthier entries about your route, the way you feel, and the stuff you thought about on the run.
