Curated by Hans Ulrich Obrist and Nadja Argyropoulou, the Marathon Marathon Project took place at the Acropolis Museum in Athens, Greece between the afternoon of Sunday, October 31 and the early morning of Monday, November 1, 2010.The 12-hour discussion was held to coincide with the 2500th anniversary of the battle of Marathon (490 BC), and addressed the notion of the Marathon race as a format of enduring collective endeavour and transcultural communication.An extension of the series of Marathon events - conceived by Obrist and held at Serpentine Galleries in London and in various cities around the world - the Marathon Marathon Project explored questions of identity, antiquity, democracy and the politics of representation at a time when the outbreak of the Greek crisis was becoming symbolic of larger socioeconomic shifts and political rifts.The participants in Marathon Marathon include Etel Adnan, Nairy Baghramian, Daniel Birnbaum, Anna Boghiguian, Simon Fujiwara, Julia Peyton Jones, Jeff Koons, Sarah Morris, Christiana Soulou, and Iannis Xenakis, among many others.
