Suggested by reader Duncan Flann, who remembers playing it as a youth in the 1970s, Spit Racing (or Spitfires) appears to have died a death with that decade.
The simple, and disgusting, idea is that players race against each other by spitting saliva as far forward as possible then rush to the point it hits the ground. Then they must spit again. And so on until they reach the finishing line first and are declared the winner. Obviously a combination of solid running and spitting ability is required to be good at the game. Duncan writes: "I remember that the fastest time achieved for the 100m was about 90 seconds. Although there was quite a strong following wind that day."
