"Just because I couldn't find a way to help her, I couldn't go in a lab and discover a cure for this disease, but I could try to raise money to get people who could find a cure for this disease," Bill said.
Bill ran alone at first, with Hayley joining her senior year in college.
I would come home like every other weekend so we could do our training runs together," Hayley said.
"I think it's definitely brought us closer together."
This year for the first time, they're bringing Ramona along.
"I'm so excited she can come with us and experience it with us. It's going to be incredible," Hayley said.
All they hope is that their story will help you think of the story, to build awareness and find a cure for Huntington's Disease.
Hayley's brother did take the test for HD, and it was negative.
The Johnstons would love for you to learn more about Huntington's Disease, and maybe even consider donating to the cause.
