George Morford is in remission but working to help other kids like him, working to overcome cancer.

FORT WORTH, Texas — When 9-year-old George Morford was diagnosed with a rare form of leukemia last year, it could’ve understandably gotten him down.

“I did laps on laps on laps around the floor,” he said.

“He got up every single day and moved his body every single day,” said George’s mother, Sarah Morford.

During treatment, patients are encouraged to exercise by taking laps around the floor using a roller bike.

Morford was on the move pretty much all day, every day, even at his worst.

“He would lean against the wall and do his miles just leaning against the wall, just walking, scraping against the wall, barely holding himself up,” Sarah said.

“I just kept going, and it started getting funner every time,” said George.

During his five and a half month stay, Morford set the record for most miles completed by a patient.

They’re not quite sure because they stopped keeping track after he passed 100 miles.

“You have to be out there on the bike from morning till the night,” said Morford’s doctor, Holly Pacenta.

Of all his rides, Morford’s last ride was his best ride. He rang the bell to celebrate finishing his treatment.

Today, Morford is in remission — and on a mission.

Every year, Cook Children’s Medical Center hosts a big party called The Blast. One of the highlights is a two-and-a-half-mile walk. Teams walk together while raising money for kids fighting cancer.

Last year, even though he was quarantined and couldn’t participate, Morford raised nearly $14 thousand and formed the biggest team, more than 130 people.

This year, now healthy, Morford did what Morford does and got moving. He walked and raised thousands, all while inspiring immeasurably more.

“Because I don’t want people to go through the same thing I went through,” he said. “It’s just not fun.”

“I’m blown away,” Sarah said. “I wish he could see himself through my eyes and our eyes. We’re so in awe of him.”

Cancer can get you down, but to get back up, Morford has some encouragement.

“I dare you to try to beat my record,” he said.
