(WBIR - Knoxville) Hundreds of people laced up their sneakers to raise money for a program that helps battle childhood cancer.

The Butterfly Fund held its annual 5k race Saturday morning. The organization was started by 10News producer Brian Barger, his wife, Misty, and another family in 2008 after both families' daughters passed away from a rare cancer.

The race raises money for the East Tennessee Children's Hospital's oncology program and helps families with the costs of fighting cancer.

"We donate to the hospital to a fund that they have. And it helps families because anytime you have a child with cancer, one child cannot work, they have to take care of the child. So, it helps out financially," said Misty Barger, a Butterfly Fund co-founder. "It may help with a house payment, it may help out with gas money, food, water or electric bills, that kind of thing."

But they've also invested in ways to make families feel more at home during the most difficult time in their lives. "We have also developed a couple of Butterfly Fund rooms at the hospital. They're for long-term patients who are going to be there for a while. And they have a more home-like setting. So, there's a bed for the parents, more in the room. A refrigerator, a microwave, just to make it more comfortable for the family.

Saturday, about 1,200 people ran in the race, and expected to raise somewhere around $30,000.
