Caroline Cronk, known as Calle, has touched hearts since she was diagnosed with an inoperable brain tumor in November. Her plight has inspired a Facebook site, a pep rally at the local high school, and a campaign led by kindergarten classmates to secure Calle a meeting with singer Taylor Swift. Her parents, Rachael and Kevin, founded Hope For Caroline, a nonprofit foundation, to offer support to families of children suffering from the same rare brain tumor. Now folks are launching a spring road race at Norwell High School to raise money for medical research. The event, Calle’s Miracle Run, will take place on April 7.
