Andrew Luck, quarterback of the Indianapolis Colts, and Riley Hospital for Children at Indiana University Health will host Field Day on April 18 at the Colts Complex, 7001 W. 56th St. A pre-selected group of 500 children from schools around the state will descend on Indianapolis for the event, designed to celebrate their completion of Change the Play, the eight-week health and fitness challenge Luck developed with hospital experts. Designed to improve the health of all Hoosier children, Change the Play was initially launched for parents and children to do at home. The program is now being introduced to Indiana schools, impacting even more Hoosier youth.
