James Corden and Gordon Ramsay vow to run the 2020 L.A. Marathon together

If you’ve ever seen the show Hell’s Kitchen, you know that chef Gordon Ramsay, who owns several Michelin-starred restaurants, has a hard time settling for second best. He likes to push himself and his culinary staff to craft perfect dishes every night, even if it takes a few screaming matches, sweat, and tears to achieve them.

But what you might not know is that outside of the kitchen, Ramsay unleashes his competitive nature in endurance races such as marathons and Ironman triathlons.

On an episode of The Late Late Show with James Corden last week, Ramsay told fellow guest, actress Dakota Johnson, and Corden about how he started training for long distance events to lose the excess weight he’d gained on the job. When he ran his first 26.2 miles at the London Marathon in 2001, it was a “disaster,” he told Corden.

“You know it’s bad when you look behind you and the tow truck is picking up the cones,” Ramsey said on the show.

Though the chef weighed close to 280 pounds at the time and was struggling to keep going, he still managed to slip under the 5-hour mark with a 4:57:00. Since then, Ramsay has shaved off about an hour and a half from that time, setting a personal best of 3:30:37 on the same course in 2004. His goal, he told Corden, is to bust through the 3:30 barrier.

Corden was impressed by Ramsay’s feats, but he didn’t exactly share the same marathon enthusiasm as the chef.

When Ramsay told the host he could run a marathon, Corden said, “Are you joking? Have you met me?”

Still, Corden was open to running a marathon, as long as he had two years to train for the distance. So Ramsay proposed a challenge: They’ll run the Los Angeles Marathon together in 2020. The two shook on the deal.

“You can walk it in seven and a half hours,” Ramsay said. He reasoned that Corden’s hiking trips around his home in Los Angeles would prepare him for the race.

“I do enjoy a short hike,” Corden clarified. “Like an hour. I don’t know people who do a seven-hour hike.”
