While it won't be a physical challenge for him, unlike some of the other children participating, it will be his way of giving back to the charity that helped his family so much when he was young, his mother Chris Lilley said.
"We are very blessed it could have been very different."
Taylor's journey started well before he was born.
He was an IVF baby after seven years of fertility treatment.
At the 12-week scan, the Lilleys were told that Taylor's major organs including his heart were outside his body.
"As you can imagine Trevor and I were extremely distraught."
Following his 20-week scan it was confirmed that Taylor had an Omphalocele (sack outside his body) that contained his liver and gut.
Tyler was born on January 17, 2006. Two hours later he was off to surgery.
"Unbeknown to us Taylor also had a diaphragmatic hernia, pericardial defect and hypoplastic left lung. Apart from the lung all was repaired during his surgery."
At 5 days old, he was diagnosed with a hole in heart. The Lilleys were told to "wait and see" how their son developed.
Aged one, Taylor weighed just 6.4kg and his gross motor development was lagging. Four months later he was in Starship having his heart fixed.
Fortunately, he recovered well and at 2-and-half-years old Taylor was being discharged from his specialists.
"Taylor has a zipper on his chest and no belly button to show for the start he had but takes this all in his stride."
He is now a very healthy boy, Mrs Lilley said.
"He is small for his age but has more energy than most kids and does not let anything hold him back."
Mrs Lilley calls him her "pocket rocket." He's the sort of child that comes home from school signed up to "everything". He's busy taking swimming lessons, softball and cricket this term.
"He's done very well."
