Backyard ultra running.

If you don't know what a backyard ultra is - it's an ultra marathon where runners repeatedly run a 6.7 kilometre loop starting on the hour every hour until only one runner remains.

The last runner to complete a loop is declared the winner.

A recent backyard ultra was held at Spencer Park in Christchurch's north. The winner of that event was Connor Aldridge who joined Nick Bewley to talk about his achievement.
