More than 1,00o athletes are expected for the 23rd edition of the Byron Bay Triathlon set for Saturday, May 12.
The competitors will race over Tempta, Sprint and Olympic distances and will be joined by 100 juniors, many of whom are competing in their very first triathlon.
The new course includes a revised cycle leg and a run under the lighthouse.
Organisers are expecting a competitive field from across Australia.
The Men’s podium is shaping up to be a battle of the northern rivers as 2017 Men’s Open runner-up Matt Slee from Suffolk Park is back with the gold in his sights, along with local favourites Harry Jones and Jack Orr.
Holly Grice is also back to defend her 2017 title, facing strong competition from Courtney Gilfillan.
Road closures from 11am till 3.30pm towards Suffolk Park; and until 4.30pm in the CBD.
