Redmond, 17, completed the 10km run in 33 minutes and 49 seconds making up almost two minutes on Breen who established a 2:13 lead after a superb 1500 metre swim leg in the Hunter River.

The young Novocastrian reduced Breen’s margin by 16 seconds over the 40km cycle leg.

Regarded by many as the next big thing in Australian triathlon, Redmond finished in 1 hour, 54 minutes and eight seconds from Breen on 1:54:34. They were both more than five minutes ahead of third-placed Will Dawes who crossed the line in 1:59:35.

Elite women’s triathlete Krystle Hockley, competing in the men’s event, was 10^th overall in the individual standings finishing in 2:10:42. Erin Doyle was second in 2:15:29 and Kylie Jessop was third in 2:21:10.

Team Lauren Parker Foundation won the team event in a time of 2:00:52. In an inspirational display Lauren Parker, who was paralysed from the waist down in a training accident in April, finished the third fastest in the team swim leg category.

Her time of 28:12 was the sixth fastest women’s time overall.

Teammate Glen Landers was the fastest overall in the cycle leg completing the journey in 57:23. Vlad Shatrov ran the final leg for the team in 34:06, only bettered by Redmond.

Redmond’s success was all the more sweet as it was the first time he had been allowed to compete over an Olympic distance course.

The 17-year-old recently raced in Germany, coming 22nd in a world cup junior race.

“We had Brendan Sexton and Aaron Royal blaze the way and Lorcan is matching and bettering their feats at the same age,” Maitland Triathlon organiser Paul Humphreys, from H-Events, said.

Sunday also featured the first race in Summer Run Country Race series, with Jack Robinson winning the 10km run in 38:01.

Dylan Cross was second in 39:43 and Scott Alder was third in 40:24.

Rachael Turnbull was the women’s winner finishing in 44:41, from Mary Yule in 46:10 and Trish Owen third in 47:57.

It was the first Maitland triathlon in five years.
