"If I have a day where I absolutely have to get a run in, you'll see me out there running at 4:15 a.m. with a little hat and gloves on, because it's pretty cold out there right now," Sumner said. "I want to be working on stuff by 5 [a.m.].
"Is it hard work? Yes," he continued. "Is it overwhelming? Sometimes. But it's pretty much fun. It's like when you were a kid and you'd play baseball; you'd play from dawn until dark. You just didn't want to go home, man. You just get as much done as you can."
Sumner has always been one to do more than his share, and he doesn't seem to be slowing down anytime soon.
He continues running and he's still quite good at it, even as he approaches 60. He tries to run at least four miles a day and in a race every weekend.
"I run in the 55-59 age group," he said. "And, 95% of the time, I'll win. Nolan Shaheed [of Pasadena] can beat me. There are others, but if they beat me, it's called the exception."
Sumner's not a big fan of losing. Then again, he's rarely had to deal with it.
"As far as winning, we win everything," he said. "I hardly know what defeat is. I don't have enough experience with it to be an expert."
He added that he used to be tough as nails, but that he's softened a bit over the years with all of the charity work he's done.
"Clint Eastwood would take lessons on me while he was doing 'Dirty Harry,' that's how tough I was," Sumner said. "Now, sad movies almost make me cry. The more you learn, the more you realize you're blessed.
He said all of his charity work is just his way of passing on the blessing.
"I love giving stuff away," Sumner said. "Can you imagine that we live in a community where it's easy to give stuff away? I'm just a holding place. We have so much stuff, and we get to just move it to places that need it.
"My friends go, 'How'd you end up down there with all those rich people in Newport Beach?' But [CdM's] only 11 miles from Santa Ana. I think something led me to be right here and help kids."
In turn, the kids are very grateful.
"We really trust him," Cummings said. "We know he's telling us what he thinks is best for us.
"He's always rooting for us."
