As the days grow shorter, I find myself on my bike before dawn. There are a few minutes where the morning light is such that the streetlamps cast multiple shadows. Three shadow Tamaras racing each other down the street. The first time a shadow comes from behind, I think its some other cyclist trying to pass me [close, on the right]. For an instant, I'm filled with adrenaline ready to take on this challenger . . . but my shadow selves have it covered.
