About 3,000 people from all over the world stopped by the Scenic City to run in one of five races within the 7 Bridges Marathon. But one of them honors a local hero. 

"The Georgia Cumberland Conference at Seventh Day Adventist is our title sponsor and we renamed the Four Bridges Half Marathon the Desmond Doss Memorial Four Bridges Half Marathon," said Mindy Quinn.

Desmond Doss was awarded the Congressional Medal of Honor despite refusing to bear arms as a medic during World War II on religious grounds as a seventh-day Adventist.

In the years before his death, Doss lived in Rising Fawn, Georgia. He was buried in the National Cemetery in Chattanooga. 

A unique true story that will soon hit  big screen through Lionsgate films, who also sponsored Sunday's marathon. 

"It's huge I don't know if they've done any other marathons but we're really excited about it," said Mindy Quinn.

But she's not the only one.

"It gives up some hometown pride. We're excited to bring some notoriety to Chattanooga. Yeah. it's definitely inspiring," said Team Hagler.

The half marathon totaling about 13 miles - led runners from Coolidge Park, over three downtown bridges like Market Street, down the Tennessee Riverwalk and eventually to the finish line.

Runners got to choose between a full relay, 5k or Family Run, and for the brave ones, a 26.2 mile full marathon that was carefully marked after last year's miscalculation. 

A full day of sweat and determination prompting the question if Sunday's runners will return next year. 

"Absolutely, I think this is something you can build upon and improve every year it's a great healthy goal," said Team Hagler.

A goal Quinn says benefits the city.

"It's really to just keep promoting scenic city and to let people know that Chattanooga is a destination to come run," said Mindy Quinn.

The movie "Hicksaw Ridge" is centered around Desmond Doss' heroic contributions in World War II. You can check it out in theaters November 4th.
