Celia Sullohern has taken out the top spot in the 10,000m Blackmores Bridge Run at the Sydney Running Festival in cool and windy conditions.

The weather blew away any hopes for the record number of gathered competitors – more than 37,000 people in total – to clock up any personal or race records as they crossed the Sydney Harbour Bridge.

Sullohern, who graduated from the University of Newcastle before moving to Yamba, chalked up a record of 33:25, just under two minutes faster than second placed Lara Hamilton of New South Wales.

Beth Croft, also of New South Wales, rounded out the top three spots in the 10km Bridge Run with a 36:09 record.

Mercy Kibarus of Kenya was the first woman to cross the marathon finish line with a time of 02:31:24 in the main event.

As well as the competitive nature of the Sydney-based marathon, there was also a handful of competitors hunting Guiness World Records instead of title times, with St. Ives local Andrew Hayden the first to bag a new tally – he crossed the finish-line dressed as a monk at the 1:43:06 mark.

Other record-chasers finished dressed as French maids and surfers, complete with thongs and a surfboard.

Sydney Running Festival director Wayne Larden said this year’s event was “bigger and better than ever”.

“More than 37,219 people have set a new record of participation this year, reinforcing the event’s status as a world class running festival and one of the world’s greatest marathons,” he said.

“Each year the event attracts thousands of runners from overseas and interstate, injecting more than $12 million into the local economy, while more than 2.5 billion people globally watch the spectacular vision of the marathon course winding around some of Sydney’s most picturesque features.”
