What is the Wellesley Scream Tunnel?

The Wellesley Scream Tunnel is a renowned part of the Boston Marathon, located between miles 11 and 12 near the Wellesley College campus. Wellesley College is an all-women's institution, and during the marathon, students gather to cheer loudly for the runners. This tradition started when the Boston Marathon was an all-male race, and the women would come out to holler at the men. The overwhelming energy and support from the young women create an incredible atmosphere, often described as revitalizing and motivational for the runners 1.
