Run Boston Strong

Put meaning behind your miles with Gray Nation Endurance at the Boston Marathon. As the world’s oldest annual marathon, the Boston Marathon is the ultimate test of endurance and spirit. The storied course carries you from Hopkinton to Boston, fueled by the electric energy of Patriot’s Day crowds. Feel the intensity of Heartbreak Hill, the history surrounding Fenway Park, and the unforgettable rush of turning onto Boylston Street toward the most iconic finish line in the world. An Abbott World Marathon Major, the Boston Marathon embodies resilience—of its runners, and of the city itself. Join Gray Nation Endurance as we run Boston Strong, uniting our miles to conquer brain tumors – once and for all.
