Please read this page before entering. Entry link at the bottom of page

Full event details/briefing packs will be emailed to all competitors 2 weeks out from race weekend.

The WAI2K 100km Course Starts at the Woodside train station in Greytown. Runners head along Underhill road for 4.5km before hitting the new Swingbridge along Underhill to Bucks road turn off.
You then follow Bucks road around to the camp site and first Aid Station area. Stock up here as you have around 14km until the next Aid Station.
Frith track is tough. You follow this until you hit Pylon track where you follow this until you take on Puffer Saddle - some say the hardest part of the course. 5-6km away is the next Aid Station at Kaitoke.
From here there is a private land section before you head up Norbett Creek loop track - a tough climb before a steep technical downhill to Rivendell area.

Another Aid Station here before you follow Swingbridge loop track (closed until 2024 unfortunately) around and then you hit Kaitoke Ridge track. This trail is steep and takes you along the ridge line until you get to Te Marua Aid Station.
A short road section before you take forestry trails towards the underpass of SH2 which takes you to Station Drive.
Once here, you hit a 'T' intersection where you now follow straight through along Goat Rock track until you hit the incline trail.

Follow this all of the way down to Cross creek, taking in the Summit, tunnels and swing bridge along the way. Once at the Cross Creek Aid Station, turn around and follow the same trails back until just past the Summit. You take a right and follow Back road around until it takes you back to the incline trail.
Now you simply follow the trail back to the 'T' intersection, hang a left and carry on until you can see the finish line area.

You run past the finish line area, and follow the Mangaroa tunnel around the 5km circuit which takes you up to Mt Climie. Now you climb! Once you are at the top, you turn around here once you cross the timing mat/turn point. Now it's time for the downhill for 6km to the finish line.

  6. THIR and/or warm hat (Insulating/Thermal/Polyprop)

  7. Water (At least 1L capacity). Front bottles advised as we have NO CUPS at all Aid Stations

  5. Tramping poles (Not for everyone I know, but if you wish to use them - feel free).

01 - Timing

This event will be timed by Onetime/Barefoot Sports NZ

You will be given a shoe tag to attach securely to your shoe. Make sure it's on PROPERLY. We need to track you over the course.

Cross all timing mats you see as you run the event. Mats will be at Aid Stations, and some select parts of the course, plus start/finish locations. Live tracking will be enabled for spectators - this can be patchy at times with signal drop-outs.

  • Final Aid Station at Upper Picnic area (14km to go) by 9 p.m. 15 hours to get to this point.

01 - The Course

Please review the course prior to registering
GPX DL available also

The WAI2K 100km course will take you on a journey of mental and physical challenges. There is around 4km of elevation over the course with a lot of vert in the first half of the run. There is a perfect mix of gravel road, single track, mud, river, tunnels, bridges, and open forestry trails to enjoy!

Please note that Swingbridge track at Rivendell is currently closed until 2025 (this shaves off 1km from the event)
