About a thousand people laced up their running shoes to compete in the Chattanooga Heroes Run Saturday morning.

It's to remember the five service members who were killed in a terrorist attack nearly three years ago. Runners Channel 3 spoke with said they're proud to honor the five men who gave the ultimate sacrifice.

The Chattanooga Heroes Run brings together all different types of people. They're all here for one reason.

"Overwhelming, only to the fact of that we know what this is benefiting, and we know the memory that we are honoring,” Deanna Boss, a runner, said.

It's emotional for runners like Boss. She competed in the five-mile race for the first time.

She knows how important it is to remember Sgt. Carson Holmquist, Staff Sgt. David Wyatt, Navy Petty Officer 2nd Class Randall Smith, Gunnery Sgt. Thomas Sullivan and Lance Cpl. Skip Wells. It's a mile for each man.

Boss is happy to know registration fees for the race will go towards a Fallen Five memorial at the Tennessee Riverpark.

"Oh, I absolutely love it. I'm completely over the moon about it because I know it's going to be amazing,” Boss said.

At the beginning and end of the race, runners shook the hands of the families who were impacted the most on July 16th, 2015.

It's James Creamer's third year being a part of the event. He served in the U.S. Army for 17 years.

"It's important for the family and it also sends out a message to the community that hey we're here to support all of our military, especially those that have died in combat,” Creamer said.

Creamer has experienced loss too. He knows events like this help the families who were forever changed nearly three years ago heal.

"I've lost a couple of my former students in combat. It's a tough thing, but it says to the family we love you. You're still part of the community. You're still our family,” Creamer said.

Organizers told Channel 3 they raised around $30,000 from Saturday’s event. That money goes toward the Fallen Five memorial.

A groundbreaking ceremony will be held on Thursday at the Tennessee Riverpark.
