A 15-year-old successfully carried his eight-year-old brother, who suffers from cerebral palsy, 57 miles to raise awareness for the disease, the Huffington Post reported.

Hunter Gandee’s exhausting effort raises a powerful message that should be heard throughout the world about the traumatizing effects of cerebral palsy, including the inability to walk.

This is Hunter’s second time completing the heroic challenge which he dubs the “Cerebral Palsy Swagger” to demonstrate “the physical and mental challenges faced everyday by those affected by cerebral palsy.”

This emotional moment demonstrates the great things somebody like Hunter can do for their community and to inspire others around them.

It only takes one pebble to start an avalanche and Hunter seems like the right pebble for the job.
