Boston Marathon switching from WBZ to WCVB, ESPN

Fans tuning in for the Boston Marathon on Patriots’ Day next year will be switching to a new channel.

After years of Marathon Monday coverage from WBZ, the world’s most iconic race will now be streamed on WCVB and its national broadcast partner, sports behemoth ESPN.

The Boston Athletic Association on Wednesday announced that WCVB Channel 5 and ESPN will serve as the exclusive local and national broadcast stations for the Boston Marathon beginning in 2023.

“We’re honored to partner with ESPN and WCVB Channel 5, respected market leaders who bring a spirit of innovation and thoughtful storytelling that will propel the mission of the B.A.A. and legacy of the world’s oldest annual marathon forward,” said Jack Fleming, acting CEO of the B.A.A.

“Both have established a tradition of broadcasting world-class athletic events, and we are excited to build on this tradition together into the future,” he added.

ESPN will broadcast the 127th Boston Marathon on its flagship channel from 8:30 a.m. to 1 p.m. Also, ESPN will have coverage of the race on SportsCenter before the live coverage and later in the day, as well as coverage appearing on other ESPN shows and platforms.

Live coverage of the Boston Marathon will air on WCVB from 4 a.m. through 8 p.m. The race will be exclusively simulcast regionally on WCVB Channel 5’s Hearst Television-owned sister stations: WMUR (Manchester, N.H.), WMTW (Portland/Auburn, Maine) and WPTZ (Burlington, Vt./Plattsburgh, N.Y.).

WCVB and all of its television partners will provide coverage of the marathon on their digital platforms and mobile apps. The Boston Marathon will also be livestreamed on Very Local Boston, and the streaming platform will host year-round content featuring the B.A.A.

The partnership marks the return of the Boston Marathon to both ESPN and WCVB, with ESPN having aired the world’s most prestigious road race in the early 1980s and then from 1997 to 2004. WCVB provided wire-to-wire coverage of the marathon from 1982 through 2006.

The field size for the 127th Boston Marathon has been established as 30,000 participants. Registration will take place over five days, from Sept. 12 to 16.

The 2023 race marks the 10th anniversary of the tragic events surrounding the 2013 Boston Marathon, which will be honored and recognized by the B.A.A.
