Now in its 43rd year, it's one of the biggest annual sporting events in New Zealand. The Lake Taupo Cycle Challenge held on Saturday didn't disappoint, with thousands taking part.
It began in 1977, with just 26 riders raising money for charity.
For some riders it's become an annual tradition, coming back year after year. Colin Anderson is one of those people - this time, riding his 100th lap.
"My first lap was in 1988," Anderson said. "I'm driving up in massive thunderstorms and I'm asking myself 'why did I ever go to Taupo?'. Anyway, it's my 32nd year coming here and love the place."
This year Anderson had a support crew along for the ride, wanting to help him celebrate his impressive achievement. And one of those supporters flew all the way from the US to support him, having met him in Paris during a cycling competition in 2007.
