Individual events are held for men and women and have been since the sport's introduction in 2002, while a mixed team relay has been on the programme since 2014.
In the 2022 Games the paratriathlon events were retained, and were for athletes with visual impairments ('PTVI' classification).
At the 1990 Commonwealth Games at Auckland, Triathlon was a demonstration event; won by Erin Baker (women) and Rick Wells (men), both from New Zealand.
Alistair Brownlee, with two golds and one silver medal, is overall the most successful triathlete in Commonwealth Games history.
Jacob Birtwhistle, Matthew Hauser, Jonny Brownlee and Vicky Holland have also won 3 medals, including at least one relay gold.
