Beauden Barrett made headlines last month after setting a fitness record at the Blues before even playing a game of rugby – but how will an actual track athlete fare in the grueling 'Bronco' test?
The Bronco is a fitness test used in rugby where players run shuttles of 20 metres, 40 metres, and 60 metres, five times over as quickly as they can.
Barrett ran the 1.2km drill in 4min 12sec, recording a personal best and setting a Blues record.
NZME's Coast took the Bronco challenge to teen sensation and Olympic hopeful Sam Tanner, who usually competes in the 1500m.
