The triathlon combines swimming, cycling, and running in a single event. The three sports are performed without a break. The winner is the one who completes the entire course first.
The sport originated in the United States in the 1970s as another training option for track-and-field competitors.
The sport debuted at the Olympic Games in Sydney in 2000. At the Military World Games in Rio de Janeiro, the competition took place in the morning, and each country could register up to six athletes in both the men’s and women’s categories.
