100 miles is 161km folks, and this course will have you climbing and descending around 10,000m (32,808 feet) across some of New Zealand's finest landscape. Thats a good honest effort!

For those less keen on 100 miles, there is also the Petzl 100km Ultra, the Altra 50km Skyrun, and a 42.2km Sky Marathon.

Course Details

Northburn 100 Miler

The first 50km loop takes 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. The third and final loop is only 10ks longer but still with steep climbs distributed through it (4000m vertical climb).  Total climb of about 10,000m.

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 one aid station about half way round each loop with nutrition and electrolyte supplements. You will also be coming back through the start/finish area at the 50k and 100k marks so you will be able to pick up your personal refreshments/gear as required. There will be some extra 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.

This is a dry, hard, rocky course mostly run over high country 4WD tracks but also including some short sections of fence lines and sheep tracks. The weather can be ‘changeable’ so your minimum gear must be carried at all times.

Petzl 100km Ultra

The course covers the first two loops of the 100 Miler.

Altra 50km Skyrun

The course covers the first loop of the 100 Miler.

42.2km Sky Marathon

Bsically you are running the same course as the 50k loop except when you get to the ‘Mirror’ corner (800m from the finish) you run straight home while all the longer distance participants carry on around the ‘loop of deception’.

    • Did the Northburn 100 Miler in 2018

      I loved this race. The race briefing was gold. Terry was so entertaining. A combo between hilarious and terrifying as he described the race. There was even a light supper the night before. The race is on stunning alpine countryside. It has a lovely warm and caring atmosphere. Sadly I pulled out at 100km and hope to pull off the miler this coming year. Highly recommend this race for the sheer challenge and small event greatness.
    • Did the Northburn 100 Miler in 2016

      practising running in a wind tunnel would help
    • Did the Altra 50km Skyrun in 2015

      Would have liked a medal for finishing
    • Did the Petzl 100km Ultra in 2018

      It gets cold and windy up the top so light weight and easily manoeuvrable clothing would help. Heat and hand warmers are really helpful.
    • Did the Altra 50km Skyrun in 2018

      Its a race you will not forget. Great experience that everyone starts off together in all distances. Amazing running with the milers when youre battling doing just 50k! Its a race that you simply must do to have the experience of absolute hell!
