The marathon route has been designed with spectators in mind. It provides spectacular vantage points on both sides of the Harbour, at no cost to onlookers.
Beginning outside North Sydney Oval, the race moves along bustling Miller Street to the Sydney Harbour Bridge. Crossing into the CBD, competitors run along stretches of Macquarie and College Streets and on to Oxford Street, the hub of Sydney's colourful gay and lesbian community.
The next leg along Anzac Parade will provide the best views for spectators, as the athletes loop around picturesque Centennial Park and retrace their route back into the city. From there, competitors heads west via the Glebe Island Bridge, which features stunning Harbour views.
Nearing the Olympic Stadium, the race will progress along a section of the M4 Freeway before finally reaching Sydney Olympic Park.
The course, which was designed in consultation with athletes, is challenging but not completely unyielding for competitors. It is predominantly flat and avoids many unnecessary corners, so fast times are expected.
