Spiridon - that´s for what who don+t know that´s the family name of first greec marathon winner in the first olympics - Louis Spiridon - and in Europe they use that name to publish magazines that promotes distance running - equivalent to american Runner´s World. the first Spridon it comes in Switzerland in the late 60s from a great runner passionate and a professional translator - Noel Tamini. That´s in french language. Lots of articles and interviews with van Aaken. That swiss Spiridon it ends in 76. A portuguese version of that Spridon magazine it stills exists in Portugal in portuguese language.
