"Why can't everyone be like Bailey? If we had more Baileys in the world, like you, the world would be a better place." – Simon Cowell
Last year Bailey Matthews captured the nation's hearts when he crossed the finish line of his first triathlon.
This year the schoolboy from Doncaster, who has cerebral palsy, is in training once again - as he prepares to launch his own family triathlon, which will raise money to buy equipment to for other disabled school children to enjoy sport.
Bailey said "It gives people to the opportunity who are not confident enough but they want to do a triathlon."
Speaking on Good Morning Britain, the 9-year-old explained that the event would only be a short distance, allowing anyone to take part as long as they are accompanied by an adult.
