Sydney will come alive this weekend as more than 40,000 runners take to the streets for the iconic TCS Sydney Marathon, with major roads across the CBD and eastern suburbs set to close for the event.

The 42km course will begin in North Sydney before taking runners across the Sydney Harbour Bridge and through Pyrmont, Barangaroo, the CBD and Surry Hills.

Competitors will then head towards the University of NSW and Centennial Park before finishing at the Opera House.

NSW Police are expecting thousands of spectators to line the route to cheer on friends and family taking part.

The wheelchair race will begin at 6.15am on Sunday, August 30, followed by the TCS Marathon at 6.30am, with both races starting at North Sydney Oval.

Police have warned motorists to plan ahead, with major road closures impacting North Sydney, the CBD and eastern suburbs.

Closures will affect major routes including the Harbour Bridge, Western Distributor, Oxford Street and Anzac Parade.

Road closures will be in place between 2am and 4.30pm on Sunday, although some special event clearways will begin operating on Saturday.

Drivers have been warned not to park in signposted clearways, with any vehicles left in those areas subject to towing and associated fees.

Police have urged runners, spectators and volunteers to use public transport wherever possible.

North Sydney is the closest train station to the start line, while Victoria Cross and Crows Nest are the nearest Metro stations.

Runners are expected to be greeted by near-perfect racing conditions on Sunday, with sunshine and a high of 20C forecast.

The Sydney Marathon was first held in 2000 as a test ahead of the Sydney Olympic Games.

The event has continued to grow, welcoming a record 35,000 runners from more than 120 countries in 2025, its first year as a World Marathon Major.

Since its inception, the marathon has raised more than $36.2 million for charitable organisations and set a new event record of $8.8 million raised in 2025.
