The NZ 6 Day Ultra Marathon is an endurance event scheduled from 29 September to 5 October 2025. The race takes place in Hagley Park, Christchurch. Participants will navigate through 2km loops at their own pace, with the flexibility to start, stop, and rest as desired. There are no check point cut-offs or hourly BYU whistles. The event offers round-the-clock catering.
The race route features a scenic, fast, and flat course on concrete paths. Participants will traverse through mature shaded woodlands, alongside picturesque lakes, and beside the winding Avon River.
In addition to the 6-Day challenge, the event also consists of other timed events spread across the week. The 72-hour race commences on Thursday, a 48-hour race starts on Friday, and a 24-hour race begins on Saturday.
