Inspired by the first marathon competition in the 1896 Olympics, the Boston Marathon® is the world's oldest annual marathon and ranks as one of the world's best-known road racing events. The historic course runs through eight Massachusetts cities and towns, challenging runners through Heartbreak Hill, culminating in the center of Boston where the official finish line is located at Copley Square, alongside the Boston Public Library!

Blood Cancer United Team In Training is a proud member of the 2026 Bank of America Boston Marathon® Official Charity Program.

We are seeking 15 individuals who are ready to make a big impact on our mission to cure blood cancer and improve the quality of life of patients and their families.
