Patrick Gamere, of Holbrook, is running to conquer cancer as a member of the Dana-Farber Marathon Challenge team in the 124th Boston Marathon April. 20.

The Holbrook resident along with more than 500 Dana-Farber Marathon Challenge teammates from across the United States and around the world will run to raise $6.25 million for cancer research at Dana-Farber Cancer Institute.

This year marks the 31st annual running of the Dana-Farber Marathon Challenge (DFMC). All funds raised by the Dana-Farber Marathon Challenge team goes to Dana-Farber’s Claudia Adams Barr Program in Innovative Basic Cancer Research, which supports promising science research in its earliest stages. The Dana-Farber Marathon Challenge has raised more than $100 million for the Claudia Adams Barr Program to date.

Invitational runners, runners who receive their entry from Dana-Farber, have a fundraising commitment of $7,500. Own entry runners, runners who have joined the DFMC after obtaining their own race entry, have a fundraising commitment of $4,000.
