AUSTIN, Texas -- The 2018 Austin Marathon brought out runners from all 50 states and more than 30 countries.

Spectrum News Sports Director Ricky Doyle took part in the event to raise money for charity.

Doyle started in last place. The other runners got a head start, as he waited behind for his big take off. He was this year's "Charity Chaser”, which means for every runner he passed, High Five Events donated $1 to a non-profit.

"I kept telling myself when I started getting to mile 22, 23, when it was really starting to hurt that it's for a good cause. I'm raising money to help people,” said Doyle.

This year's charity, Camp Kesem, offers free summer camp for children whose parents have cancer.

"A lot of these kids, aren't even 12 yet and they are taking care of their parents. They are taking care of their siblings. They have to grow up way to fast,” said Kiri Chung with Camp Kesem.

An avid runner, Doyle managed to placed 331 in the race, passing thousands of runners along the way. While he is completely exhausted after his first marathon, remembering the faces of those benefitting from his run, kept him going.

“It’s much better than just running for yourself,” said Doyle.
