FORT WORTH — Rob Davis was just four years old when his mother died from heart-related issues at age 29.
"I was the one who found her in bed having trouble breathing," he recalled.
A few years later, Davis' dad died of a heart attack. He was 42.
For Davis, who is a cardiac nurse, heart disease is both personal and professional.
"I take care of patients who are usually older in their 50s to 70s all the way up to 90s who have done a lot of damage to their hearts," he said.
In his professional role, Davis helps save the lives of patients at Texas Health Harris Hospital Fort Worth, but he wants to do more.
So he's pedaling with a passion to promote heart health.
Davis will bike his way across the country to raise awareness and money for the American Heart Association.
He's now in training — riding 20 to 35 miles at least three times a week for now — and will gradually increase those distances.
"I know I can do it" Davis said.
The 30-year-old Burleson man will be on the road for 60 to 100 miles each day, facing unknown weather conditions and varying terrain.
Davis couldn't do anything to save his parents from an early death, so now it's the care of others he's worried about.
"If we are able to make a difference in one person... if we are able to make a difference in 10 people... even better, what I am promoting is people to go out and get screened," he said.
