The 15th annual Blue Cross Blue Shield of Arizona Walk On! Challenge is complete. 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. Due to the statewide shutdown of schools in March 2020, backpacks will be mailed to schools at the end of May. Grant recipients will be announced at the end of May.
