The DetermiNation program is the American Cancer Society’s nation of athletes determined to end cancer. This powerful and inspiring movement saves lives by enabling athletes to dedicate their training and participation in marathons, triathlons, cycling races, and other endurance events to a lifesaving effort to fight a disease that has already taken too many lives. Over the years, thousands of athletes have had an experience of a lifetime while raising millions for the fight against all types of cancer. With every step taken and every mile conquered, these determined athletes are helping create a world with less cancer and more birthdays. The American Cancer Society DetermiNation program (formerly known as Charity Runner) began in Chicago in 1996. The program expanded nationwide in 2007, and now includes a variety of races across the country and is continuing to grow. To sign up today, click the button below.
