Do you have a 100k Ultra-Marathon on your bucket list? Are you a seasoned Ultra runner looking for a PB? This fast, almost entirely off-road course offers a great opportunity to test yourself over the 100km ultra distance, without hills and traffic.

Race from Kaiaua on the beautiful Seabird Coast to Waihi Train Station on this fast and flat course. The new 48km Hauraki Rail Trail extension from Miranda to Kopu is complete, and the 14km from the start at Kaiaua School to the trail head at Miranda is made up of a mixture of tarmac, footpath, gravel path and grass, including a cool section through the Robert Findlay Miranda Wildlife Reserve.

Pop on your head-lamp, tie on your tail-light and follow the lead bike as you head out on the quiet country road and trails in the wee-small hours on your way to the first aid station at Miranda. From there it’s 100% trail as you mooch down to Waitakaruru then head east across the Firth to Pipiroa and on to Kopu. Enjoy the early morning tranquility of rural New Zealand and say hello to the grazing cows and horses before you arrive in downtown Paeroa. 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, crossing bridges and passing through a 1km long train tunnel in the spectacular Karangahake Gorge. You’ll soon arrive at the 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 100m and that's nearly all in the last 15km before Waihi. The first 80% of the ultra is essentially flat and the last 20% is slightly rolling with a couple of short pinches to test your stamina.


The Miranda Holiday Park is just 10 minutes drive from the start line and is a great place to base yourself for this event. Don and Sue are kindly offering a 10% discount to all Trail Trilogy folks for the event and they have all sorts of accommodation options plus fantastic hot mineral pools!

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

Note that the aid station 5km from the finish is not accessible to race entrants or the public, so it is not a relay change point.

If you have some gear you'd like to discard and leave at the start line, then pick up again at the finish line, that's cool. We'll have a gear drop area at the start line and we'll happily transport your stuff to the 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.


There won't be buses taking competitors to the start line, you must make your own arrangements. Please try and car-pool where possible. You can do this via our Facebook page.
