ANN ARBOR, Mich. — A Michigan teenager carrying his 7-year-old brother on his back has battled heat, rain, fatigue and more to finish a 40-mile walk to raise awareness about cerebral palsy.

Fourteen-year-old Hunter Gandee walked from his high school not far from the Ohio boundary to the University of Michigan in Ann Arbor. He packed his brother, Braden, throughout the two-day journey.

On Sunday, they strolled up a winding road toward the university's wrestling center. Asked how he felt, Braden said simply: "Tired."

Hunter acknowledges there was talk of stopping the walk around the 30-mile mark due to chafing on his brother's legs.

Called the Cerebral Palsy Swagger, the trek's goal was to raise awareness about cerebral palsy and to put a face on the muscle disorder.
