Help Speedway #FuelMiracles for Kids by Rounding Up September 3-6. It’s time to #FuelMiracles and save lives for kids treated at Phoenix children’s Hospital. The weekend of September 3-6, round up at the register to help Speedway raise funds for local children and make a difference in our community. Thanks to speedway’s and it’s customers’ generosity, Phoenix Children’s Hospital will be able to address the most challenging health issues of today and prepare and prevent those to come.
