From Broadway to the New York City Half Marathon

February 14, 2019

From appearing in social media, to meeting with lawmakers on Capitol Hill in Washington, DC, Broadway star Jason Danieley and his late wife Marin Mazzie vigorously advocated for the concerns of cancer patients and their loved ones.

Now, as reported by Playbill and Broadway World, in honor of Mazzie (who passed away from ovarian cancer last September), Danieley will be lacing up his sneakers and advocating for patients in a brand new way by participating in the 2019 United Airlines NYC Half on March 17. He will run in a special Team Marin in honor of his wife with Brian d’Arcy James.

“Marin and I were drawn to CSC by their mission statement, ‘to ensure that all people impacted by cancer are empowered by knowledge, strengthened by action, and sustained by community,” Danieley said. “We could think of no better way to share our compassion for others by assisting CSC in any way we could.”

In addition to honoring Mazzie through the United Airlines NYC Half, we will also present the first-ever Marin Mazzie Award for Empowerment alongside Jason on April 16 at our spring celebration in New York. Danieley and Mazzie received the Award for Empowerment in 2016, and CSC has renamed it after Mazzie. The award will recognize a member of the entertainment, sports, or media worlds who uses his or her diagnosis to advocate for others.

“This year it is an honor to put 13.1 miles under the treads of my running shoes to raise money to help them continue their great work,” Danieley said.
