2017 Boston Marathon Banners Unveiled On Boylston Street

New banners that celebrate the Boston Marathon are now flying above city streets ahead of the 121st running of the race on April 17.

Four-time Boston Marathon champion Bill Rodgers joined Olympic marathoners Desiree Linden, of the U.S., and Eric Gillis, of Canada, to unveil the banners on Boylston Street Tuesday morning.

Linden has run Boston several times, but Gillis is running for the first time this year.

"Watching it on TV over the years has been a treat, but being here in person now I'm starting to get the energy of Boston and the race," Gillis said Tuesday.

Boston Mayor Marty Walsh also said during the banner unveiling that April 15, the anniversary of the 2013 bombings, will again be One Boston Day.

It's a day for public service in the city to honor the bombing victims, survivors and first responders.
