Sports

Swim, bike, run, back to back, with the clock still running through the changeovers.

A flying disc, an end zone, and no referee: players call their own fouls even at international level.

Six a side over a high net, with three touches allowed and the ball never permitted to land.

Handball in a pool too deep to stand in, so nobody stops swimming for the whole match.

Freestyle and Greco-Roman, where the second forbids attacking below the waist. Both end with holding shoulders to the mat.

The lowest score wins, the course is different every time, and the handicap system exists so unequal players can compete.

Running, jumping and throwing, grouped into one sport. The events share a stadium and almost nothing else.

Eleven a side, one ball, and almost no use of the hands. The rest of the world calls it football and reserves soccer for arguments.

Road racing is a team sport disguised as an individual one: most of the squad exists to shelter one rider from the wind.

A board game with its own world federation, tournaments and doping rules — which is exactly why people argue about the label.
