I spent most of the day at the Tokyo Marathon yesterday. Really nice time. Warm and sunny all day. Good friends. Hundreds of thousands of people walking around the city with not a single piece of paper on the ground (and no garbage cans, too). Runners snaking their way along the race wearing every piece of clothing imaginable. Just fun. I was there to support the iRun by Joseph Tame, where he strapped on some iPhones and an iPad and offered the world a live digital venue with which to join his run to support children with cancer in Japan. Images of Joseph running here. All of my photos from the marathon here.
