80km bike course
Enjoy an 80km bike course across varying terrain where the distance and route will challenge you to balance your effort and your nutrition to stay strong and have enough left in the tank for the run.
18km run
The perfect distance whether you’re competing or completing, the 18km, multi-lap run ensures plenty of crowd support topped by incredible vibes as you cross the finish line to claim your medal.

Pro Athletes
The T100 Triathlon World Tour showcases the world’s best triathletes with 20 men and 20 women competing in every event, all racing for the chance to be crowned T100 Triathlon World Champion and earn a slice of the $9m on offer.
Â
Contracted athletes are selected by coming in the top 10 of the T100 Triathlon World Tour in 2024 or through outstanding performances over the last year. Meanwhile additional Hot Shot contracts go to those athletes who’ve earned the right to race through Olympic success or their standing in the sport outside of their PTO World Ranking Position.
Â
On top of that, there are ‘Wildcard’ athletes at each event – chosen by exceptional recent performances, top athletes coming back from injury or maternity or more Olympians stepping up in distance.
Â
The T100 Triathlon World Tour is the official World Championship Tour of long-distance triathlon, organised by the PTO (Professional Triathletes Organisation) and recognised by World Triathlon, the sport’s global governing body.
