Officer Jayme Green is getting ready for one of the most important bike rides of his life. But instead of heading out to protect the public, he's using his biking skills to raise money for his cousin Granton Bayless. He's been diagnosed with Severe Combined Immunodeficiency and is unable to fight off disease.

"Even though he's got a lot of tubes coming out of him, he's still a happy baby," says Green.

He is getting sponsors and raising money to help pay for Granton's enormous medical bills.

"I can help with the financial trouble and medical bills. Most likely they're going to have some sort of medical care for the rest of his life" he says.

"We're going to be keeping in contact with our walkie-talkies," says his brother Toby Grundman.

Green won't be alone on his 300 mile, five-day trek to Granton's hometown of Boliver, Missouri. His brother Toby will drive the support truck.

"I wanted to help him out cause you don't want to go alone on something like this and make sure he keeps hydrated," says Grundman.

As Jayme begins his trip, officers Jerry Monasmith and Sergeant Guy Gardener ride beside him. His police escort ends at the edge of the city limits.How are his legs feeling?

"Oh they're great. I've got 60 more miles to go," answers Green.

Then Jayme is left to finish the ride on his own. Sgt. Guy Gardner has no doubt Jayme will make it all the way.

He says, "He's in good shape. He's a good bike officer. If anybody can do it, he can."

And it's the thought of Granton that keeps Jayme going.

"Keep praying for him. Make sure he gets better. Lot of prayer, gonna need a lot of prayer," says Green.

Jayme and Toby will be camping Monday night in Burlington, Kansas.
