Lucas six, was born with Lissencephaly – a rare brain disorder which affects development – however his brother, Noah, eight, ensures that despite his disability, Lucas doesn’t miss out on anything.
The brothers’ incredibly close bond has even seen them participating in marathons together, with Noah pulling his brother around in a specially made cart.
The pair – who live in Idaho, in the US – most recently, completed a youth triathlon, involving a 200 metre swim, a one mile run and a three mile bike ride.
“They’re inseparable and they always have had a really close bond,” their mum, Alissa, told BuzzFeed.
“After the race, Lucas was just watching Noah’s every move and was just so proud… you could see it in his eyes.”
