World Snail Racing Championships
It might not be the fastest race in the world, but having two or more snails racing either on a straight-away or circular track while there are numbers on the sides of the shell so everyone involved can tell the difference between the snails that are racing. The annual competition is held in the United Kingdom, but there are several smaller races held throughout the world.
In case you wanted the sport of bowling to be even more challenging, then replace the typical ball with a frozen turkey and attempt to knock down pins that are represented with plastic soft drink or water bottles. Many ice rinks will host this sport in the United States and Canada, mostly in smaller venues that don’t host professional hockey games.
