Athletics Arithmagons

Athletics is a collection of sporting events that cover running, throwing, jumping and walking. Athletics competitions can be traced back as far as 776 BC to the ancient Olympic games. Did you know that the Olympic gold medal is not actually made from gold, instead it is plated with 6 grams of gold.
