"Jaylon is bubbly. He has this spirit about him that is almost angelic," His mom, Whenddi Eberhardt, said.
The 9-year-old is diagnosed with generalized dystonia and cerebral palsy.
"He's not able to walk, yet. I like to say the word yet because I like to keep an optimistic mind," Eberhardt said.
Grant will be competing in the disability field and crossing the finish line with his favorite teammate, Jill Matte.
They met through Ainsley's Angels, which provides special racing chariots and runners to push disabled athletes in races. Together, Jaylon and Jill have participated in about 20 races.
Today, his family affectionately calls Jill Jaylon's auntie.
"When we're not racing, we are hanging out at the house. It's a family," Eberhardt shared.
Jaylon and Jill will be racing their first marathon together this Sunday.
"He gives meaning to running. I remember I do this for him." Jill shared.
