It’s called the World Marathon Challenge and starts this Sunday.

When asked if he is ready for the biggest physical challenge of his life Fallon said, “As ready as you can ever be. I’ve done the physical training for it the last couple of months, and now it’s the mental preparation for it.”

The task is obviously and overwhelming one, but the reason he is doing this all lies in the story of an 8-year-old boy from Illinois.

Fallon said, “In the back of mind I’m going to be thinking about Jonny.”

Jonny Wade died last Christmas from a rare form of brain cancer at 8-years-old. Fallon never met the boy or his family but he followed his brave fight through social media.

Now Fallon is out to raise money and awareness for pediatric cancer in Jonny’s memory.

The first marathon will be in Antarctica, and the last one will be in Australia.

Fallon says when he will undoubtedly fall weak, and need a pick me up, he will have a picture of Jonny on him to give him the extra encouragement he may need to cross the finish line.

He added, “I think there is going to be a little angel carrying me.”

If you would like to help raise money for the cause you can do so here.
