*Al Roker is planning to participate in the 26-mile New York City marathon on Nov. 7, and it appears as if his wife will be his biggest cheerleader.

“I think he’s a little nervous, but he’s so ready,” Deborah Roberts told People about her husband’s preparations, which included running 20 miles with a trainer last weekend. Roberts, meanwhile, is already an avid runner.

“It’s such a sore subject in my house,” she says about the light-hearted competition between them. “I’ve been running for 30 years, and I have a knee injury. He started a year ago, and he’s doing fine.”

Roker, who shed 115 pounds after a gastric bypass surgery eight years ago, said that he doesn’t enjoy running and is still waiting to experience the infamous “runner’s high.”

“Somebody told me that running is 20% physical and 80% mental. I feel that if I’m running six miles, that sixth mile is the hardest. If I’m doing eight miles, the eighth mile is the hardest. I don’t know – it’s this weird thing,” he explained.

For his part, Roker says he is “down to a 13-minute mile [though] I still get passed by grandparents.”
