MEMPHIS, Tenn. -- This weekend thousands of runners from around the world will descend on Memphis for a very important cause, the St. Jude Marathon. This is the marathon's 15th year and it brings millions of dollars to St. Jude and the city of Memphis.
"You really appreciate things when you lose them," said Chandler.
Chandler, a junior in high school, suffers from a rare form of brain cancer.
"It wasn't until I got double vision that I really knew something was wrong and then from there I got two brain surgeries and from there it was what do we do now?"
His family turned to St. Jude. Where he has been receiving treatment. Chandler said he's not just fighting cancer, he's getting a new look at life.
"Who wakes up and says, 'wait, I didn't throw up this morning? This is a good day.'"
Helping children like Chandler is why thousands of runners from around the world descend on Memphis every year.
"At the end of this race. I want you all to think about the fact we expect to approach $60 million in funds generated for the lifetime of this event," said Rick Shadyac, the CEO of ALSAC, the fundraising arm of St. Jude.
It's not just money generated for St. Jude.
"This is about a $20 million economic impact to Memphis and its one we're extremely proud of," said Malvin Gipson, of the Memphis Sports Council.
Chandler, who plans to run the St. Jude half marathon next year, has a message for everyone running or helping, in some way, this year.
"I can never thank you enough for helping and supporting this," he said.
St.Jude's message to drivers on race day, who might have to take longer or alternate routes is be patient and know the extra time spent in the car is part of a much bigger cause.
Extra security along the race will be on hand and St. Jude is asking for race goers to bring clear bags to hold your belongings.
