  1. Dear Lady or Sir!
    I am interested to take part in the 10 km race. I am surprised that your race is called Saiko Ecomarathon Tokyo, because it is not in Tokyo, but far away!!!
    Where exactly will be the start and which Hotels are situated close to the start?
    I am Hanno, from Germany, Born 17.11. 1942,
    Until now I had Competitions in 126 countries., but not yet in Japan!
    Best regards Hanno
