Grandma's Marathon hosts runners from all over the world.
This year, one doctor from Haiti will go the distance for the sake of his patients who mean the world to him.
"The first word that comes to mind when I think of Dr. Manno is compassion," said Joan Guite.
Dr. Emmanuel "Manno" Mareus cares for 400 diabetic patients in Limbe, Haiti.
One hundred of them are insulin dependent.
Dr. Manno said, "in Haiti if you live in the country side area, being a diabetic is a death sentence."
He says insulin treatments costs 50 dollars a month. For most of his patients who only make a dollar a day, that means staying alive is not affordable.
Dr. Manno, though, doesn't put a price tag on life.
"It's a big family," he said. "They're the reason why I wake up every morning. They give my life a sense."
He's taking his practice outside of the clinic and running 13.1 miles in his patients' shoes.
"Last year when I was here, I heard about this marathon and I said I'd like to do it to raise money for the diabetic patients that cannot afford insulin."
Dr. Manno has been training for Grandma's Half Marathon for over a year.
"All I want is to be able to get more insulin and not be able to say to patients we don't have insulin," he said. "That's the worst experience for me when we run out and don't have money to buy it."
Dr. Manno will not turn patients away even if they cannot afford his care. It's what he calls 'agape care.'
"[It] means complete service to a person without expecting nothing," he said. "Just find pleasure in helping another person make his life better."
Guite, a retired registered nurse said, "he faces his clinic shutting down periodically because he can't pay his staff. And that's where agape comes in."
The Ministry in Medical Missions, out of Moose Lake, Minn. and Dr. Manno have been working together for six years.
Over that time, they've raised about $50,000 for care.
"They've been a blessing in my ministry. Those are my angels," said Dr. Manno.
Guite responded, "[it] chokes me up."
"We can't cure everybody but we can make a big difference in the lives of the people that he cares for," she continued.
Dr. Manno has never done a half-marathon before, but he's ready to hit the ground running all for his family.
"If I'm healthy and I can do it, why not do it for them?" he said. "That's the way I see it."
"I have 100% faith in him, unless he gets injured some way," Guite laughed. "That man has a heart. He is going to finish."
