It's being called a story of extraordinary brotherly love — an 8-year-old boy determined to have his younger brother with special needs live a full, normal life helped him complete a youth triathlon.

Noah Aldrich said, "He most of the time doesn't get what I get to do. Like when I play sports, he has to just watch. I just wanted to finish with Lucas." (Via KIVI)

The boys' parents told NBC older brother Noah pulled and pushed 6-year-old Lucas the entire time as he swam, biked and ran in the Y-Not Mini Triathlon in Boise, Idaho, earlier this month.

According to KTVB, Noah pushed Lucas in a jogging stroller for the course's 1-mile run, pulled the stroller behind his bike for the 3-mile ride and made the 200-meter swim with a harness around his chest that was attached to a raft holding his brother.

But 8-year-old Noah's remarkably mature decision to help his brother came as no surprise to his family.

According to a blog about Lucas on the Aldrich family's CaringBridge page, Lucas was born with a rare genetic condition that's left him unable to walk, talk or eat on his own.

But even though he's only 8, Noah knows not to let that stop him from doing normal things with his brother every day. (Via NBC)

"I like everything about him; he's perfect. We go on walks. We just walk around the neighborhood. Are you having fun, little buddy?" said Noah. (Via KTVB)

Siblings have teamed up like this before.

​As for Noah and Lucas, they were able to finish the youth triathlon in just over 54 minutes. And their parents and even the announcer at the race that day said they couldn't be prouder.
