If you're in any of those categories, here's how you can watch the Marathon on Monday, April 21, from home or elsewhere: Live coverage of the Boston Marathon will exclusively air on WCVB-TV beginning at 4 a.m.

When the elite racers approach the start line of the 129th Boston Marathon, four athletes will have a chance to defend their titles — and two will be racing for three-peats. The champions of all four elite races a year ago will be back in the field for this year’s race, set for Monday, April 21.

On Patriots’ Day, nearly 32,000 runners will tackle the rolling hills and unpredictable weather along the 2025 Boston Marathon course. Some will be experienced athletes, some will be making their debut at the 129th running of the iconic race, and some will be celebrities and celebrated sports stars.
