Jamie Soward and Peter Wallace will attempt to break a world record when they headline a CPR Endurance Contest at Hawkesbury Racecourse on Monday.

The Take Heart Australia Day event, part of Windsor Rotary's Hawkesbury Heartstart Campaign, will see participants attempt to set a new world record for “the most people trained in CPR on the one day”.

Every hour between 9.30am and 5pm, trained professionals will run free CPR training sessions for groups of 100 people at a time.

Each week 500 Australians die from Sudden Cardiac Arrest, accounting for almost 20 per cent of total deaths around the country.

Newly-listed charity Take Heart Australia is on a mission to dramatically decrease this statistic by training as many Aussies as possible in CPR, kicking things off on Take Heart Australia Day.

Professor Paul Middleton, Clinical Associate Professor of Emergency Medicine at University of Sydney, said we need to make understanding of CPR common knowledge.

"Administering CPR early can double or triple the chance of survival," he said.

"Our goal is to make surviving Sudden Cardiac Arrest the norm rather than the exception."
