A brilliant relay event for teams — grab some running mates, club mates, schoolmates, or workmates and see if you run 100 km through the night from Waihi to Kopu, and back to Waihi. Challenge your corporate or club rivals to the ultimate workplace team-building experience.

The experience of running through the night and encouraging your teammates to reach your final destination will be something you will all learn from and cherish. On this amazing "made-for-a-relay" course you'll discover the good, the bad, and the ugly side of yourself and your mates, and learn about tackling a seemingly monumental challenge, overcoming it, and reaching your shared goal together.



It may be flat, but it ain't easy! Whether you have a 100 km Ultra-Marathon on your bucket list, or you're a seasoned Ultra runner looking for a PB, this is the event for you. The course breaks down into nice, achievable chunks so you can 'tick off another 10 km' at each aid station. You'll experience the deep-dark night, the sun coming up over the Coromandel Ranges, and the Hauraki Plains coming to life, then the beautiful scenic Karangahake Gorge and Ohinemuri River as you make your final push for the finish line...


This fast, almost entirely off-road course offers a great opportunity to test yourself over the 100 km ultra distance, without hills and traffic.

Race on the Hauraki Rail Trail from the historic Waihi Train Station out to Kopu (just short of Thames), and back to the Waihi Train Station on this fast and flat course.

Pop on your head-lamp, tie on your tail-light and follow the Rail Trail in the wee-small hours on your way to the first aid station at Waikino. From there you'll head west through the Karangahake Gorge to Paeroa and on to Hikutaia. Enjoy the early morning tranquility of rural New Zealand and say hello to the grazing cows and horses before you arrive at the Aid Station turnaround point in Kopu.

Check your gear, check your watch, take a deep breath and then head back south down the trail to Pipiroa and on to Paeroa again. Negotiate the pathway through town to the aid station before you depart Paeroa and enter the most scenic and varied section of the Hauraki Rail Trail. The course runs alongside the Ohinemuri River, through the spectacular Karangahake Gorge - in daylight this time. You’ll soon arrive at the aid station at Victoria Battery in Waikino then follow the beautiful river-side trail all the way to the finish line at Waihi Station.

The course rises only 100 m and that's nearly all in the last 15 km before Waihi. The first 80% of the ultra is essentially downhill or flat and the last 20% is slightly rolling with a couple of short pinches to test your stamina.




  • There are Male, Female, and Mixed team categories (no age groups).

  • A team can have up to 10 members.
  • A mixed team must have at least 2 female members.
  • Each team member can run as many or as few legs as they like.
  • The only stipulation is that your baton changeover is at one of our Aid Stations. See note re AID STATIONS below.
  • Your timing transponder is your baton, and it must be passed from one team member to another at an Aid Station.
  • Your transponder must be securely fastened to your ankle or the timing mat will not register your time.
  • There is a $50 charge for a lost transponder - secure it firmly!


There are 9 aid stations (which are the relay change points) on the Hauraki Hundee Ultra Marathon course. They are at Waikino (10 km), Paeroa (21 km), Hikutaia (33 km), Puriri (42 km), Kopu (50 km), Puriri (58 km), Hikutaia (67 km), Paeroa (79 km), Waikino (90 km).

They will provide water, fruit, and electrolyte drinks.

You can arrange for your support crew to meet you at any of the Aid Stations to supply you with your preferred hydration and nutrition (see course map).

There is also an Aid Station 4.5 km from the finish but it is not accessible to support crews or the public, and it is not a relay change point.


Cups will not be provided at the aid station. Please BYO cup/bottle or carry your own nutrition/hydration requirements to help us reduce our event waste.

You should prepare to be self-sufficient for the duration of the race. The aid station will have some fruit, water, and electrolyte drink available to help with your race nutrition, however this should be considered a top-up only, and you shouldn't rely on it for your full race energy or hydration needs.


There will be cut-off points at the Kopu aid station (50 km) at 9.30 am, Paeroa aid station (79 km) at 1.00 pm, and the final cutoff at the finish line will be 4.00 pm.

You are responsible for your own navigation. You should take time to learn the course before you start your race. See course maps.


If you have some gear you'd like to discard and leave at the start line, then get to again at the finish line, that's cool. We'll have a gear drop area at the start/finish line/event HQ for you so you can wrap up warm again after your race. Be sure to clearly mark your gear bag so it doesn't get picked up by somebody else by mistake.
