Sutherland Shire athletes have dominated at the Sydney Harbour 10k.
Caringbah runner Amy O'Halloran broke the Sydney Harbour 5k course record in the women's event in 17 minutes, 32 seconds edging out Cronulla's Audrey Hall who finished second.
Shire athlete Ali Najem won the men's race in 15.50.
More than 6,000 runners took part in the event under sunny skies where Lisa Weightman won the women's 10k event and smashed the course record in 31:55.
Lauren Reid came second in 33:29 while third place went to Marnie Ponton in 33:49.
Victorian athlete Lachlan Barber won the men's event in 29:59 ahead of Sam Byrne (30:15). Kieren Tall finished third in 30:42.
Weightman was delighted with her race.
"My goal was to go as hard as I could. I had some guys and my husband helping me out and I'm so stoked, first time under 32 minutes," she said.
"I'm looking forward to the Australian Half Marathon championships next week."
Barber said it was a great race.
"The course was gorgeous. I happened to just get under 30 minutes and just a second off my PB which was really great," he said.
"This is only my second 10k. I knew I had to push it hard to the finish line. I back my kick to the finish line and I didn't have anyone to chase down so I thought I'd put on a bit of a show and push for the under 30 minutes."
Event director Wayne Larden was thrilled with how the event had gone.
"The flat and fast course which hugs the Sydney harbour providing stunning views throughout the [race] continues to deliver a terrific experience for both elite and everyday runners. What a fantastic way to get fit and enjoy what is undoubtedly the most spectacular 5k and 10k course in the country," he said.
Starting at the historic Sydney Rocks, the 10k course was a one lap loop which hugged the harbour foreshore travelling along Hickson Rd, through Cockle Bay, Darling Harbour, Pyrmont, through the Barangaroo parklands and back into The Rocks to the finish line at the Overseas Passenger Terminal, Circular Quay.
The 5K course also took in some of Sydney's most beautiful sights. The course started at George Street, the Rocks, continued around the edge of Sydney Harbour, under the famous Sydney Harbour Bridge before an out and back section along Hickson Road and back into The Rocks to the finish line at the Overseas Passenger Terminal.
