The 121st running of the Boston Marathon was another incredible Patriots Day in Massachusetts. It was a warm race for the runners, with temperatures in the high 70s and strong sun in the morning. Viewing the race from mile 24, so many good-willed fans cheered along the runners down the final stretch of the course towards Boston. Katherine Switzer made her return to the race 50 years after she was the first woman to run the Marathon in 1967. She wore her original bib number 261. In all, Marathon Monday brought out the best in people to make for an amazing day.
