The Wellesley campus is just before the halfway mark on the Boston Marathon course, and students come out to cheer runners in what has become known as the "Scream Tunnel". Student have been cheering on runners since the first running of the marathon. In 1966 the school heard word that a woman was running in the race and turned out in numbers in cheer her on. Bobbi Gibb claims to have heard them from half a mile away. The women ran out into the road and raised their arms to form a tunnel. Diana Chapman Walsh, who would later serve as Wellesley president from 1993 to 2007 was present for the 1966 race. “The word spread to all of us lining the route that a woman was running the course. We scanned face after face in breathless anticipation until a ripple of recognition shot through the lines and we cheered as we never had before. We let out a roar that day, sensing that this woman had done more than just break the gender barrier in a famous race.” Once women were officially allowed to register for the 1972 race the campus cheer tradition became more popular. Before current crowd control techniques that only allow students to cheer from the south side of the street, students would form a tunnel anywhere from 5 to 8 feet wide.
