On a sabbatical for the first half of 2020, Barrett has not played a professional match since last year’s World Cup.
And despite not playing even before the lockdown, Barrett returned to training with his new Blues teammates yesterday to stun the rugby world.
According to the All Blacks website, the 28-year-old “blitzed the gruelling aerobic fitness test in a club record time of 4.12”.
The statement adds: “The impressive time was also a personal best for Barrett and was two seconds clear of halfback Jonathan Ruru.”
The Bronco test is explained as: “A 1200m aerobic Shuttle Test involving running to-and-from a start line to 20, 40 and 60m marks, five times without a break”.
“The purpose of this test is to a get an estimate of maximal aerobic running speed.”
Coach of Barrett’s ex-franchise the Hurricanes, Jason Holland, says of the feat: “I don’t think I’ve ever heard of that quick.”
