The restaurateur posted a photo of himself from the event to his Instagram account on Monday, captioning the shot: “Celebrating the premier of #MasterChef by running my first #10K.”

The new season of the FOX show kicked off on the same day.

Graham Elliot went on to recognize his MasterChef co-hosts, Gordon Ramsay and Joe Bastianich, writing: “Thx @gordanramsay @jbastianich for the support and encourage!”

The slimmed-down star, who completed his 10K in a reported time of 1 hour and 16 minutes, peaked at close to 400 pounds, before undergoing weight loss surgery.

In 2013, Graham Elliot chose to receive a sleeve gastrectomy, which aided in his weight loss.
