Together with many thousand other runners, I participated at Greifenseelauf on Saturday, September 20th. Start and finish were in Uster, Switzerland. I came across some good pictures of the well organized event on this Innovation Wings posting. Main sponsors of Greifenseelauf were COOP, UBS, and adidas.
