Champions know that ego counts, but numbers don’t lie: to be the best, you’ve got to beat the best.

That’s why Powerade has developed Powerscore, a series of physical tests created in collaboration with the NSW Institute of Sport (NSWIS).

And who better to set the bar than some of Australia’s most elite athletes?

North Sydney Oval.

It was a wet and muggy morning at North Sydney Oval when the rivalry that pitted mate against mate and code against code entered full swing.

Billy Slater, the man widely considered the greatest NRL fullback of his generation, sized up against Mitchell Johnson, a bloke as fearsome as fast bowlers come.

But it didn’t stop there. The top of NSWIS’s crop of athletes, along with ironman Kendrick Louis and ironwoman Lizzie Welborn, also stepped up the challenge.

As did a few recent AFL and NRL retirees in the form of Mark Gasnier, Justin Hodges, Brad Johnson, and Cameron Mooney.

It was a battle of power, agility, speed, and endurance as each athlete took to the turf – with some soaring solo and others running neck and neck.
