Organizers of Tokyo's Ome Marathon expressed their condolences to the victims of the Boston Marathon bombings, stressing they intend to work "hand in hand" with the race's host to help overcome the tragedy.

Since signing a sister-race agreement nearly 40 years ago, the Ome race organizers and the Boston Athletic Association have worked closely to promote the sport, including the exchange of runners between the two races each year.

"Two runners who competed in our race ran the Boston Marathon this year" and three of the Ome organizers traveled to the U.S. for the event, a spokesman for the Ome Marathon told The Japan Times on Thursday.
