The Petzl 100km Ultra

Saturday 22nd 2025 - 6am Start

Study the maps of the Course Profile page!

The 100k course covers 2 maps, each loop starts and finishes in the same place – great to catch up with your supporters!

The first 50km loop take you from 200m above sea level (Start/finish) up near the most central point in New Zealand at around 1660m (2600m vertical climb). The second ‘loop’ is another 50km loop with a climb of 3750m.

There will be plenty of marshals along key areas of the course. The course will be well marked with directional arrows, plastic poles and reflective tape at night.

There will be two aid stations with nutrition and electrolyte supplements, each one about half way around each loop. You will also be coming back through the start/finish area at the 50k mark you will be able to pick up your personal refreshments/gear as required. There will be multiple fresh water re-fill positions (creeks) along the course so a water carrying capacity of about 2L per person should be adequate there will be some compulsory re-fill points.
