HOPKINTON, Mass. (AP) - The final wave of runners in the Boston Marathon is headed for Boston.

The last wave of the 36,000 runners crossed the start line in Hopkinton at about 11:42 a.m. Monday.

Among the final wave were 40 members of Team MIT Strong, including students, faculty and alumni running in honor of MIT police officer Sean Collier, who was allegedly killed by the suspects in last year’s marathon bombing.

A contingent from the Boston Fire Department was also in the final wave. Many of them were first responders in last year’s attack and were running in memory of Boston firefighters Michael Kennedy and Edward Walsh, who died in a recent fire in Boston’s Back Bay neighborhood.
