Organised by the Taupo Half Marathon Society the Mizuno Half Marathon, one of Taupo's iconic events, is held on the first Sunday in August each year.

With around 3000 entrants expected, it is New Zealand's largest stand-alone half marathon. Popular with runners and walkers of all abilities, the flat, scenic out-and back route takes in fantastic views of the mountains and Lake Taupo.

Proceeds from the event are distributed to young sports people within the Taupo District council area through the Mizuno Half Marathon Sports Fund. The society supports Lake Taupo Hospice and entrants in the Mizuno Half Marathon may add a donation to their entries.

Sponsorship is also given to Waipahihi School’s Ironkidz and the Taupo Harrier Club’s 5K series with a schools participation competition encouraging school children to give sports a go, and to Taupo’s inter-primary schools cross country.
