Among the participants was Rotorua born and raised Olympic cyclist Sam Bewley, 27.
"It is a lot bigger than I thought it was going to be. It is going to be fun, it's a unique experience and has brought the crowds. Everyone wants to do something different.
"I have done the kilo before but I have never done this on a runway.
"I think it's going to be awesome, every year it gets larger and larger.
"Eventually we want to get everybody on bikes, and not just for a week."
