As part of tightened security measures, officials have asked spectators not to bring backpacks, large bags or coolers to the event, and all such items will be searched by event organizers. A warning was also issued against flying any kind of drone or model aircraft along the route, which is expected to attract up to one million spectators.
About 30,000 people will take part in the race throughout various sections, which will begin at 8.50 am with the impaired mobility segment, followed by the wheelchair segment.
While reigning women's champion Rita Jeptoo of Kenya is currently banned for having used drugs and will therefore not take part, last year's winner Meb Kefligizhi, the first US male to win the event since 1983, is again participating. Kefligizhi, who will turn 40 next month, became the oldest winner since 1930 when he took first place with a time of 2:08:37.
The running team of the Martin Campbell Foundation, set up in memory of Martin Campbell, an eight-year-old boy who was killed in the 2013 attack, is also joining the race. Members running on behalf of the foundation include his neighbor, his soccer coach and other members of the local community.
The jurors in the trial of Dzhokhar Tsarnaev, who last week was convicted of all 30 charges against him in connection with the bombing and its aftermath, have been ordered by judge to stay away from the race, as part of their instructions to avoid events and media coverage related to the marathon.
Also barred from taking part in the marathon is Kendall Schler, the disgraced winner of last week's St. Louis Marathon, who was stripped of the title and barred from Monday's event after it transpired that she had entered the racecourse only after the final checkpoint, before crossing the line with a time of 2:50:30. After an investigation had been conducted by course officials, second-placed Andrea Karl was awarded the winners' medal.
