CAMP MABRY, Texas -- More than 1,500 runners raced through Camp Mabry Sunday morning, including an Austin father battling brain cancer.
"It helps you both have hope and some contact with humanity," said Iram Leon.
Leon used to race by pushing his 8-year-old daughter Kaina in a stroller, and he even won a marathon doing that. Now they run together, and Sunday she set a personal record.
Kaina is her father's encouragement and training partner because he is battling brain cancer.
"My brain surgery was almost exactly four years ago, and you hear about some of the bad stories and low survival rates and it makes you want to put your head in the sand," said Leon.
Instead, he's sticking his neck out and helping fundraise for the Head for the Cure 5K. It's an event that has funneled money into brain cancer research and support.
"We've raised close to half million dollars in cancer research just from Austin in the past three years," said founder, Matt Anthony.
Leon and his daughter say this race is just a stepping stone into even bigger competitions. She's working toward a triathlon, and he is running the Boston Marathon this year.
"No matter what, I'm going to die at some point so I'm just trying to do some living," said Leon.
ESPN is featuring Leon in a documentary to be released this summer.
