The 8th annual Covenant Health Knoxville Marathon set a new record with Sunday's race.
With the sound of the gun bright and early Sunday morning, more than 7,500 runners began their trek. Participation was up by 1,000 people compared with last year's race.
Throughout the course, hundreds of people all across Knoxville were there to cheer on the racers. But the best part of the day for many of the runners was crossing the finish line.
All of the races ended on the 50 yard line in Neyland Stadium.
But the Mulholland family had extra motivation behind each step.
Twenty-one members of the family ran to raise money for a cure for their brother's disease.
Pat Mulholland, a runner and ORNL scientist, lives with ALS or Lou Gherig's disease.
The disease effects your muscles and motor functions. It doesn't allow Pat to run anymore.
To celebrate his life and raise money for a cure, his family decided to travel from all across the country to run together in his honor.
"It was great to do it for him, for the family, for the cause. Hopefully they will find a cure soon," said Monica Erb, Pat's sister.
The family raised $13,000 for the Tennessee ALS Association, an organization dedicated to research and patient services. The family says the ALS Association has helped Pat tremendously in his fight with the disease.
