Boston Marathon

Today was the 118th running of the Boston Marathon, the first since last year’s terrorist attacks at the finish line, but this time everything went off exactly as planned. American Meb Keflezighi won for men and Rita Jeptoo of Kenya defended the women’s title she won last year. Today’s race hosted the most runners in two decades and the most spectators ever, more than 1 million people lining the street, creating both challenges and opportunities.
