60 hours into an ultra marathon

Yesterday Midday Report spoke with ultra marathon runner Julia Chamberlain as she was competing in the World Backyard Ultra Marathon. At that point, 15 New Zealanders had been running 6.7km every hour since 1am on Sunday morning. Well it's now Tuesday and six runners are still going - that's 60 hours and almost 400 kilometres under their belts. Sam Harvey speaks to Charlotte live from the race.
