Big crowds, black ribbons for Boston at London Marathon

LONDON (Reuters) - Undaunted by the Boston Marathon bombings, big crowds lined the route of London's mass road race on Sunday to cheer on around 36,000 runners, many of whom wore black ribbons to honour the dead and wounded.

Hundreds of extra police were deployed to secure the first race in the World Marathon Majors series since two explosions near the finish line of the Boston Marathon on Monday killed three people and wounded 176.
