Nathan Breen won his fourth Richie Walker Aquathlon title in the last five years on Saturday.
Another strong field of competitors took on the 33rd running of the annual race in warm conditions at its traditional Gunnamatta Bay Park course at Cronulla.
Breen, who already held the 2015, 2016 and 2018 titles from the iconic shire event, added the 2019 trophy to his collection with another strong performance.
The 21-year-old Cronulla Triathlon Club member was the first athlete out of the water after the swim leg and held off his challengers during the run to secure victory in a time of 27 minutes 38 seconds – almost three minutes faster than his winning time last year.
Kurt Fryer (27.52) and Josh Ferris (28.40) finished second and third.
Emily Jamgotchian was the first female to finish in a time of 32.28.
Matilda Offord (33.43) and Caitlin Sendt (35.30) rounded out the minor placings.
Adam and Penny Hummerston (48.19) won the mixed teams event, while Sidney Mulholland and Kathryn King (55.32) won the female teams race.
It was a family day out for the Alexanders, dad Craig (29.08) finishing fourth in the opens race and first in the 40 to 49-years age division.
Son Austin won the boys 7 to 9 age group, while daughter Lucy won the girls 13 to 15 age race. Mum Nerida finished 22nd overall in a time of 46.01.
It was the 33rd race since Walker, a promising triathlete and lifeguard, died suddenly and tragically from a heart attack during a race at Tamworth in 1986.
