"Everyone's calling me Superman and they're asking me why I'm not flying and I keep telling them Superman walks," Superman Walks Founder Thomas Mills III said.
At the Superhero Scramble, heroic figures were all over the place.
But Thomas is working to rescue one little boy confined to a wheelchair with cerebral palsy.
His name is Tommy.
"He doesn't understand why he can't go, why they don't make races wheelchair accessible where he can race," said Laura Mills.
Tommy's mom, Laura, has been doing mud races for quite some time.
She never thought Tommy would be doing one with her.
"I met up with Superman Walks and he turned my dream into a reality," Laura said.
"I tell her let's do it. We're going to take your son through a race and she agreed," Thomas said.
Laura found Superman Walks online, where Thomas shows that even kryptonite won't stop him from running a good race.
"I was doing about 110 miles an hour and I hit a guard rail. A reflector pole took my leg off right then and there," Thomas said. "I went through some really, really dark days."
That motorcycle accident was almost 10 years ago.
And now Thomas and his crew of 41 trekked an almost 10 mile obstacle course with Tommy in tow.
Where the motto is, "We start together, we finish together."
"They just embraced us and now we're like family," Laura said.
Uphill and across water, the team trudges on. But there's some anxiety.
"I am trying to raise him to be an independent man in this world. And he wants to do this," Laura said. "And it's scary for me, but I will not hold him back."
Although he's faster than a speeding bullet, slow and steady wins the race. And that's why Superman walks.
People as far as Quebec came to help Tommy race. The team finished in about four hours.
