About the Mary O’Brien Memorial Run

In the past 15 years, M.O.M.’s Run has raised over $180,000 benefiting the Claudia Adams Barr Program in Innovative Basic Cancer Research at Dana-Farber Cancer Institute.  We owe this success to the thousands of runners, countless volunteers, and generous sponsors who have partaken over the years.  Thank you!

We’re gearing up for 2017 to be our biggest year yet!  Whether it’s to celebrate moms, promote health, to commemorate cancer survivors or to honor those we’ve lost, we hope you’ll join us on Mother’s Day for a 5K, delicious food and a fantastic raffle.
