Tokyo Marathon International Friendship Run

Get in the mood for Sunday's Tokyo Marathon by running precisely one tenth of the distance yourself, at this laid-back event on Saturday afternoon. Expect to see a mix of Japanese and international runners working their way around the 4.2195km course in Odaiba, then slurping down some oshiruko red bean soup and heading to Oedo Onsen Monogatari for a complimentary dip (all included in the ¥3,000 participation fee). Okinawan eisa drumming and acrobatic hashigonori performances add to the fun. If you'd like to take part, you'll need to register at the Expo2013 event at Tokyo Big Sight on February 21 or 22.
