Actors, singers, sports stars and even a cartoon character are among the famous faces running the 2026 London Marathon.
This year, celebrities range from those who have taken part previously - like Wicked actress Cynthia Erivo or McFly’s Harry Judd - to those such as Sinners actor Jack O’Connell and retired Formula One champion Sebastian Vettel who are taking on the challenge for the first time.
Other famous participants include Scottish comedian and author Fern Brady, Traitors star Harry Clark, and fitness coach Joe Wicks - who will run the 2026 marathon alongside Peppa Pig star Daddy Pig, who is running both real life and the cartoon.
They are just a small handful of the almost 60,000 people who will be at the starting line this Sunday, with each raising funds for charity.
Here are 16 of the celebrities set to run during the 2026 London Marathon, with a full list available here.
