It's finally time for the Boston Marathon. Here are the celebrities, influencers, professional athletes, and notable participants running in 2025.

Of the 31,670 people who were entered in the 2025 Boston Marathon, 28,845 runners started the race, meaning that 2,825 did not line up in Hopkinton on Monday. Before the event, the Associated Press reported that there were some concerns this year among international runners about an increase in border security under the Trump administration.

Monday featured many moments that sparked emotions of awe and inspiration for runners and spectators alike. William Richard watched the race in 2013 with his family when the Boston Marathon bombing took place. His son Martin was the youngest victim killed that day, according to The Washington Post.
