DetermiNation Endurance Series
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. Just like hard work goes into your event training, the American Cancer Society gives it our all through things like breakthrough research, patient programs and services, and a free 24/7 cancer helpline. Together, we’ll tackle every course, rally every community, and stay absolutely relentless in the fight against cancer.
