We are a leading cancer-fighting organization with a vision to end cancer as we know it, for everyone. We are improving the lives of people with cancer and their families as the only organization combating cancer through advocacy, research, and patient support, to ensure that everyone has an opportunity to prevent, detect, treat, and survive cancer. 

DetermiNation is the American Cancer Society’s event endurance program, spanning a variety of sports including cycling, running, hiking, yoga, and more. The collective efforts of the dedicated athletes who use their fortitude to help raise funds to take down cancer are nothing short of amazing.

When you join DetermiNation, you’re not just participating in an endurance event. You’re pushing yourself to help save lives from cancer.

Together, we’ll tackle every course, rally every community, and stay absolutely relentless in the fight against cancer.
