Running may be solitary at times, but runners often use the inspiration of others to motivate them, both in training and racing. Heroes and heroines can inspire us. I have a photograph of Grete Waitz, nine-­time winner of the New York City Marathon, that I keep on my refrigerator door. It inspires me and reminds me that everyone - even Grete Waitz - lacks motivation at some point, and we all can get through those moments.
