“I was diagnosed at stage IV, without the care from my team at Dana-Farber I wouldn’t be here. So for me it’s that simple. I run to give back to the place that gave me a second chance at life so that others can do the same.” - Abbey, a runner for Dana-Farber's Boston Half team We can’t wait to cheer on Abbey and our entire team on November 8! 💙

"I run because, after cancer, I needed to find myself again. For a long time, my body was something I associated with sickness, treatment, fear, and uncertainty. We are so much more than what has happened to us. It may give us challenges we never asked for—but it does not get to decide who we become."- Rachel, a runner for Dana-Farber's team this fall in the Boston Half
