Boy, 8, completes triathlon with his disabled younger brother

Never has the lyric "He ain't heavy, he's my brother" been more appropriate.

Eight-year-old Noah Aldrich's brother, Lucas, 6 is his best friend.

And they like going everywhere together - including a mini-triathlon.

Lucas has a rare genetic condition, lissencephaly, which leaves him unable to eat, walk and talk on his own.

Noah didn't let Lucas' condition stop them from taking part in the triathlon together.

He completed the run by pushing his brother on a stroller.

For the bike ride, he attached a stroller carrying Lucas, and pulled it along.

Both Noah and Lucas completed the swim after Noah strapped himself to a harness that he attached to a floating raft safely carrying Lucas.

Their father, Brian Aldrich said that they have always been close.

"They definitely have a special bond, the two of them," he said.

"You see Lucas light up so much when Nolan enters the room. It just brings a smile to your face when you see the love between the boys."

This is what Noah had to say about his little brother: "I like everything about him. He's perfect."

Can someone pass the tissues please?
