A minute's silence is due to take place before the start of the Marathon of the North on Sunday as organisers and participants pay their respects to victims of the Boston Marathon bombings.
5000 runners are expected to line up for the event, which is in its second year.
The Marathon of the North will take place a fortnight after bombs exploded near the finish line of the Boston Marathon, killing three people.
