They've walked more than 4,000 miles, from Disney Land to Disney world in honor of their daughter who lost her life after visiting Magic Kingdom.

Julia Cobb, 8 years old, lost her battle to Bone Cancer on October 29, 2013 after spending a wonderful day with her family at Walt Disney World.

"We should not have lost Julia to cancer. No father should have to watch his daughter die and go through pain and suffering," said Julia Cobb’s father, Jonathan.

After her death the Cobb family felt like they needed to do something to raise awareness about pediatric cancer.

Throughout their journey, family members have kept Julia Cobb (photo held up at right) in their hearts. Shown are Jonathan, Jennifer, Jonathan David, Jenna and Jaxi.

"We decided we needed to walk from one Magic Kingdom to the next,” Julia's mother, Jennifer Cobb said. “We can't go to Julia's Magic Kingdom just yet but we can go on a massive trip to encourage others and inspire others."

Almost one year ago the Cobb family, including their 13, 11 and 4-year-old children, slipped on their sneakers and hit the road.

The family from Texas traveled to DisneyLand in California, where they began their 4,000-mile journey across the country.

Over the course of their journey the family members went through several pairs of shoes as they hiked through Colorado snow and the Mojave desert.

Along the way they met with several families whose children are battling cancer, and they said meeting those families was the most rewarding part of their journey.

"We wanted to be her voice for millions around the world," Jonathan said.

Jonathan is a cancer survivor. After seeing his daughter’s fighting spirit, the family decided to start the JuCan Foundation.

“Julia was always focused on what she could do. That’s why we always called her the ‘Ju-Can’ because she was always focused on the can part of cancer,” Cobb said.

After 320 days on the road, the Cobb’s can say their journey is complete.

Saturday, with “JuCan” on their shirts, and Julia’s final Father’s Day card in their hands, the family took the last few steps in their journey as they walked into Magic Kingdom.

"You know this was the last place we saw her. So it's sad that it's over but I know that it's time for the next phase of our journey," said Jennifer Cobb.

Now the family has made it their mission to continue their work with JuCan, Julia's foundation.
