Running prodigy Sam Ruthe has shattered a record that's stood for more than three and half decades. The 16 year-old ran his 1500 metre heat in 3 minutes and 38.62 seconds at the New Zealand secondary schools track and field championship in Hastings. He broke the previous record held since 1989 by Commonwealth games runner, Richard Potts, shaving off six seconds. Sam Ruthe spoke to Lisa Owen.
