We are excited to launch the 14th annual Blue Cross Blue Shield of Arizona Walk On! Challenge. As the largest health care provider in the state of Arizona, our goal is to educate and inspire fourth- and fifth-grade students, their teachers and their families to focus on healthy choices that can be made daily with the 5-2-1-0 goal. Registration for the 2019 Walk On! Challenge opens October 16, 2018. To learn more about the 2019 Walk On! Challenge and the 5-2-1-0 goal, please choose from the Teacher or Parents tabs above.
