What racers and reviewers say
- RaceCheck (Mark L.)Raced 2016 · aggregator · Mixed
2016 World Championship: well-marked deep-water start with rough swell in the days around the race; closed, well-marked roads with large packs and a confusing double-loop. Found organisation underwhelming for a world championship: wave start confusion, very long narrow transition and extra fees; volunteers praised.
- RaceCheck (Paul R.)Raced 2016 · aggregator · Positive
Glassy, clear swim in roughly 33 minutes, a strong 2:23 ride and a 4:39:32 finish in mid-20s C (mid-70s F) sun. Stayed in an apartment 800 m (0.5 mi) from the start: quiet, canal views, good value.
- RaceCheck (Keren M.)Raced 2016 · aggregator · Positive
Sheltered water at Mooloolaba Beach, a flat motorway bike with two hilly loops including a very steep hill, rife drafting, and a mostly flat two-loop coastal run with a headland section. Excellent organisation before and after, perfect 24 C (75 F) weather.
- RaceCheck (Alexandros T.)Raced 2016 · aggregator · Positive
Pleasant clear swim at a good temperature, a mostly flat bike with drafting everywhere and a run that is mostly flat apart from one hill repeated four times, with a headwind on the return. Transition cramped and uneven underfoot.
“Everything worked like clockwork.”
- RaceCheck (Amy K.)Raced 2016 · aggregator · Positive
Choppy sea swim in warm water, a largely flat bike spoiled by heavy drafting, and a hilly run that took a toll. Praised the course and setting but reported long registration queues and a congested banquet.
“far too much drafting”

Gave the race 4.9/5 as the gold standard for 70.3 racing: well organised with strong community support.
- Dietitian Approved (Taryn Richardson)Raced 2024 · blog · Mixed
Group report from athletes who travelled from across the world: the ocean swim was far rougher than expected (blinding sun, motion sickness), but several set big personal bests and a relay team podiumed.
“far rougher than expected”

Pro race report describing a choppy ocean swim after a cloudy night, a flat and fast bike and a two-lap run around the Mooloolaba Esplanade.
- Coach CoxRaced 2016 · article · Positive
