The Damon Runyon Cancer Research Foundation will hold the 10th Annual Runyon 5K at Yankee Stadium, with 100% of funds raised directly supporting innovative cancer research. Participants are encouraged to raise funds for cancer research. The Runyon 5K is the only event of its kind held inside the iconic stadium. The course winds through the ballpark’s concourses and ramps, and upstairs between levels. The 2018 Runyon 5K is presented by MetLife Foundation.
