Dreydon Sobanja's aim is to spark kiwi kids by writing stories about inspirational athletes. His latest book is the Kiwi Runners' Family Tree - Volume Two.
It's a history of athletes and their coaches - running stars of the last twenty years.
Volume one covers the 1800s to 1999.
Dreydon Sobanja has also published three children's books about mountaineer Sir Edmund Hillary, aviator Jean Batten and motor racer Bruce McLaren.
Dreydon has an inspirational story of his own to tell as well: beating depression, and shedding a huge amount of weight to become a competitive triathlete.
He talks to Kathryn Ryan, along with Olympian middle distance runner Angie Pettie.
