Here are some of the celebrities running the marathon.

Among those running the marathon are people who, in addition to being talented and famous, are apparently in great shape, too.

Here are a few of the recognizable faces that may dash by. (We will be updating this post with their finish times later in the day.)

The professional actors heading out include Randall Park (“Fresh Off the Boat,” “Always Be My Maybe”); Jennifer Connelly (“Labyrinth,” “Top Gun: Maverick”); Claire Holt (“The Vampire Diaries,” “Aquarius”); and Greg Rikaart (“The Young and the Restless,” “Days of Our Lives”). Broadway-goers might spot Carrie St. Louis, who played Glinda in “Wicked.”

Nev Schulman, the host of MTV’s “Catfish,” will race, as will Vinny Guadagnino of “Jersey Shore” fame.

Fans of “The Bachelor” may recognize Peter Weber, who also competed on “The Traitors,” and Matt James, as well as the “Bachelorette” contestants Zac Clark and Joe Amabile. The host of two seasons of “The Bachelorette” and a one-time contestant, Tayshia Adams, will also run.

News fanatics can keep an eye out for Jacob Soboroff, an NBC News correspondent. Amy Robach and T.J. Holmes, former “Good Morning America” anchors who co-host a podcast, will be running.

Other big names include Casey Neistat, a YouTube star; Karen Sarahi Gonzales, a beauty influencer; Phoebe Robinson, a comedian; Sebastián Yatra, a Colombian singer; and Haley Kalil, a model.
