A Michigan teen walked 40 miles in effort to raise awareness for cerebral palsy with his younger brother who suffers from the disease strapped to his back on Sunday.

14-year-old Hunter Gandee planned the walk for weeks in support of his 7-year-old brother Braden, who suffers from the disorder that makes him unable to walk. But, according to
Fox News, all the planning did not prepare him for what he would endure over the two day walk from Bedford, Michigan to Ann Arbor, Michigan.

The teen almost gave up halfway. "Honestly, yes, there was a point that we did consider stopping," Hunter said to Fox. "Braden's legs — the chafing was getting pretty bad. We did have to consider stopping. It was at about the 30-mile point."

With encouragement and aid from family and friends the boys were able to complete the race, even though it took longer than anticipated. The brothers were accompanied by their parents and other two siblings and were also joined by a caravan of cars and supporters.

"Whenever I'm going through something that's difficult and doing something that's hard, I see him and how he worked through it, and it just kind of pushes me through," Hunter said to CBS News.

The ultimate goal was to raise awareness for those who suffer from Cerebral palsy, like Bredan, in hopes to inspire new mobility aids and medical procedures, Fox reports.
