Among the tens of thousands of competitors pounding the pavements between Hyde Park and Bondi Beach in the City2Surf were several Australian politicians.
Sydney athlete Harry Summers won the event in 42 minutes, while Queenslander Cassie Fien was the first woman across the line five minutes later.
Steve Moneghetti's 25-year-old race record of 40.03 still stands.
Opposition Leader Bill Shorten completed the iconic race as well as Labor MP Andrew Leigh, while South Australian Greens MP Mark Parnell ran the half marathon in Adelaide.
"Off for a jog with a few good friends," Mr Leigh tweeted before the run.
Mr Shorten crossed the line in 80 minutes, with an average pace of 10.5km/h, while his Canberra colleague was 25 minutes ahead of him.
The politicians weren't the only eye-catching athletes running through Sydney's bays on Sunday morning.
Gorilla and platypus costumes, traditional surf life savers and even a giant inflatable pig family were spotted along the 14 kilometre course.
Australian wheelchair athlete Kurt Fearnley crossed the line first in the wheelchair race in under 30 minutes.
More than $4 million has so far been raised for charity from the event, in which over 80,000 competitors took part.
