Thousands of marathoners surge up Barcelona’s Passeig de Colom, running towards the city’s monument to Christopher Columbus. I waited until there was a break in what was a nearly continuous flow of runners – and when it came, it left the foreground empty, allowing me to emphasize the body language of those upfront. Although there are hundreds of people in this picture, the eye naturally moves to the man who salutes the crowd as he makes the turn at the monument. The Avenue, lined with palms and lights, frames the runners as their faces diminish into the background. The huge mass of people flowing through this setting expresses the grandeur of the event itself.
