Tour De Force Ride Honors 9/11 Victims, Sean Collier

BOSTON (CBS) -- A ride to remember wrapped up in Boston Sunday as cyclists made their way from ground zero in New York to the Boston Marathon finish line.

Three hundred bicyclists on the "Tour De Force" wore uniforms of dark blue with touches of red, remembering those lost 14 years ago in the 9/11 terrorist attacks.

When they hit Boston, police officers and firefighters escorted them with sirens to the iconic blue and yellow finish line on Boylston Street.

The last leg of the 280-mile ride is called Sean's Ride, for MIT police officer Sean Collier, killed by the Boston Marathon bombers.

"We're doing it for Sean, Sean Collier," one rider said.

Among a group of Cambridge police officers rode MIT police officer Dusty Miller who called the ride a "great tribute" to his friend.

Riders stopped for a moment of silence before continuing on to Black Falcon Fish Pier, where the ride ended and many went back to New York by bus.
