Richard Turpie of Christchurch was a man on a mission on Saturday - attempting to run 100 kilometres to raise money for a Hamilton boy who needs a heart transplant. Five-year-old Chase Porter needs a new heart after being diagnosed with Barth Syndrome, a rare genetic condition that has caused his own to fail. Richard, who's 22, was moved by Chase's plight and his battle to survive, and decided he wanted to help. He'd never officially run even a marathon before.
