More than 5,000 people took off from the starting line to help raise money and awareness for kids like seven-year-old Allie Dominguez and adults like Evan Prichard who suffer from Type 1 Diabetes.
"It's really special to me because I have all these people with me here," Allie said.
"I think it's just nice to know that people are out there supporting you and it's always fun to have people come out, walk, and have one of those days where you feel like everybody's behind you," Prichard said.
For 19 years JDRF has been holding these walks to not just raise money but raise the spirits of the families also effected by this epidemic.
"The JDRF One Walk is one day out of the year that kids can celebrate having Type 1 Diabetes. Everyone here today is celebrating them and here recognizing them. So it's a day for them to feel important and to feel loved," Mike Brin, executive director of JDRF, said.
It's a love that has helped Allies' mom, Kerry and her older brother, Joey.
"It's just amazing to have all these people come together. It's just you can feel the love and support. It just makes us feel like we are not alone," Kelley said.
"It's kind of crazy to think about just how many other families go through this with certain members of their family," Joey said.
Hold onto the hope that one day soon, they'll be a cure for Allie and the millions more living with Type 1 Diabetes.
"We hope for a cure. That there will be no more needs we have to worry about. All the needle sticks, having to worry about insulin, and how many carbs to eat, just a cure," Kelley said.
JDRF raised more than $600,000 during Sunday's walk. To find out more about T1D or how you can help log onto JDRF.org.
