Paramedic doctor on the run for charity

On Sunday thousands of runners will pound the pavements - as the annual Auckland marathon takes place. And one runner might stand out - because he'll look more like someone working the event. William Law works full time as a doctor at Auckland City Hospital and picks up shifts as a paramedic for St John in his spare time. So he's decided to run the Auckland Half Marathon wearing his St John uniform and 10kg response pack to raise money for the charity. He spoke to our producer Lydia Batham about why he's doing it and what challenges it will present.
