Olympic sprint champion Anna Meares has shown just how powerful her acceleration is – by taking on a Porsche Boxster in a segment filmed for an Australian TV show, and winning.

The 11-time world champion – four of those titles coming in the 500m sprint, as did her first Olympic gold medal at Athens in 2004 – can accelerate from 30kph to 60kph in just three seconds, according to 60 Minutes Australia, which arranged the challenge.

Up against TV presenter Peter Stefanovic who was at the wheel of the 300 brake horsepower sports car, Meares took on the Porsche over 80 metres from a rolling start … and left it trailing.

The cyclist versus sports car duel comes just two months to go until the Rio Olympics, where Meares defends the individual sprint title she won in London four years ago.
