OLATHE, Kan. -- Six fathers sharing a common but heartbreaking bond have decided to fight for their children by hitting the road.

Their children all suffer from a rare and fatal form of cancer called neuroblastoma.

The men have been riding their bicycles across the country to raise money and awareness for the disease. They call it the Loneliest Road Campaign because of the long, difficult road ahead for their children.

The group spent Wednesday evening at an Olathe fire station.

"My name is Michael Love, and I'm riding for my daughter, Taylor, who was diagnosed December 2006," Love told KMBC's Martin Augustine. "It came out of nowhere and it came on fast."

"My name's Randy Monroe and I'm riding for my daughter, Marissa Monroe," Monroe said.

"My name is Kevin Sims, and I'm riding for my daughter, Sydney Sims," Sims said.

"My name is Ven Davis, and I'm riding for my son, Kai Elijah Davis," Davis said. "Kai has shown me how to be a man, I guess. Through the pain, through all the injections, radiation, he knows that it's going to be OK."

"My name is Richard Brown, and I'm riding for my son, Jack," Brown said. "It gives you time to think about your son and what they're going through. And it also resolves the determination to continue on."

"My name is Alec Oughton, and I'm riding for my daughter, Grace," Oughton said. "My daughter Grace is definitely my motivation. She's been through way more than climbing the Rockies or being short of breath because of the altitude."

The road is grueling and the men miss their families, but they said they keep fighting for their kids.

"It's hard, but this is where we need to be," Love said.

On Thursday the group will bike to the Sprint Campus, one of the sponsors for the ride, and then they will continue on to Columbia.
