Archie - Living with cerebral palsy
Ellie Symonds, Tom Aggar and Sarah Storey are just three athletes hoping to win gold at the Paralympic Games.
Some of the athletes taking part have a condition called cerebral palsy which means that their brains have trouble communicating with their muscles.
It affects around 1 in every 400 children in the UK, including 10-year-old Archie who tells his story in the video.
