By running the Chicago Marathon, Caleb Prewitt continues to raise the bar for the Down syndrome community

Oct 16 2025 • By Roger Mooney

Caleb Prewitt continued to shatter the perception of what someone with Down syndrome can’t do when he conquered the 26.2-mile course at the Bank of America Chicago Marathon on Oct. 12.

Caleb, 18, became the youngest person with Down syndrome to earn an Abbott Star for running one of the original six World Major Marathons.

The Jacksonville native, who receives a Florida education choice scholarship for students with unique abilities managed by Step Up For Students, is also recognized by the Guinness Book of World Records as the youngest person with II2 (Intellectual Impairment, including those with Down syndrome) to run a half-marathon (13.1 miles). He did that when he was 16.

Since 2020, when he began running as a means of getting exercise during the COVID-19 pandemic, Caleb has completed 47 triathlons (swim, bike, run), five half-marathons, and now one full marathon.

The marathon was his most daunting endeavor, requiring months of training. The race took its toll – he experienced leg cramps after 20 miles. Undeterred, he pressed on and continued to cheer those who lined the course and were cheering for him.

“That went on for miles and miles, and I couldn't stop him,” Karen said. “I wanted to save his energy, and he just wanted to do it. I said, ‘You know what? This is his race. He can do what he wants.’”

Those in the Florida running community who have come to know Caleb during the last five years, and the faculty and staff at the North Florida School of Special Education, which he has attended since he was 5 with the help of his scholarship, wouldn’t have expected anything less.

He is known around school as “Mr. Mayor” for his always sunny disposition, and he is a star on social media with more than 31,000 followers on Facebook and more than 45,000 on Instagram to his Caleb’s Crew pages.

Running the marathon for the National Down Syndrome Society, Caleb raised more than $2,000 for the charity. There were 40 teammates from the National Down Syndrome Society team cheering him on at various points along the course.

Caleb’s dad, David, greeted him at the finish line with a long hug and a kiss.

“So proud of you,” David told his son.

WHAT A DAY! I’m still emotional after running alongside Caleb yesterday for his first full marathon. The Chicago crowds did not disappoint and the energy level was 💯 for most of the race. Leg cramps caught up with Caleb at mile 22, but he pushed through and crossed that finish line with enough energy for a post-race dance party 🕺🏻 So thankful for his spirit and grit and the joy he has for life in general. He loves people and this race was momentous for us all. Soaking in the victory today - so proud of you Caleb! @Chicago Marathon @National Down Syndrome Society #DownSyndromeAwareness #TeamNDSS #NoLimits

Caleb was one of 17 charity runners in the event, which meant he was featured around Chicago in ads for the marathon, and his story appeared on the race’s website.

The 17 and their families met at a reception the day before the race.

“Their stories were all great. You know, everybody's story is great,” Karen said. “It's just that I think ours is great, too.”

That prerace publicity and the fact that he and Karen wore blue shirts with “Caleb’s Crew” on the front made him stand out somewhat in the field of 54,000 competitors.

“The crowd was amazing,” Karen said. “The whole way there was support and people cheering for Caleb. Everywhere we went, they knew his name, so that was a thrill.

“It was an awesome experience. What a wonderful day.”
