Competitors, volunteers and spectators will stand in silence at the start of Sunday's Marathon of the North, to remember the victims of the Boston bombings.
The tribute was announced by the event founder and organiser Steve Cram.
He said the race safety plan has been reviewed in the light of the Boston attacks as the security of participants is paramount but said he didn't anticipate problems.
