BOSTON – Hannah Kilson and Caila Kilson-Kuchtic mother-daugther duo were featured as Boston Marathon runners for Horizons for Homeless Children alongside Tara Spalding, Horizons’ Chief of Advancement and Playspace. “We use a two-generation model because we know the success of the child is so dependent on the success of the parent,” Spalding said. “And that’s why we were so excited that Hannah and Caila, this mother-daughter duo, were going to run the marathon for us because that really is our philosophy, that strong relationship between parent and child.”
