The 100 Mile.
4AM & 8AM FRI 5 DECEMBER 2025 | THE TRAILS OF WHAKATU - NELSON
Why the 100 Mile?
Warning: this race is not for the faint-hearted!
This might just be the hardest miler in Aotearoa. It’s 160km of single track, unformed track, and forestry roads, thousands of metres of vert, sweat, dirt, dust and probably some tears, and will be an adventure like no other.
Are you game enough to take it on?
The 2025 course.
Embark on an unforgettable 100-mile adventure from the heart of Nelson’s CBD. The journey begins on Selwyn Place, with the ultimate send-off down Nelson’s vibrant main street, Trafalgar Street. From there, join the Maitai River Trail, following its banks past Waahi Taakaro Golf Course to tackle your first climb — the 2.5km ascent to Tantragee Saddle.
From the saddle, link onto the historic Dun Mountain Railway for a steady climb to Third House Shelter, then along the ridge to Jenkins Hill, where sweeping views over the Barnicoat Range await. Descend into Stoke, soaking in the cheers of locals as you reach Saxton Hockey Pavilion — your second crewed aid station and a chance to recharge.
Fuelled and ready, you’ll climb back into the Barnicoat Range via the winding Bike Trails in Silvan Mountain Bike Park, skirting the ridge before returning to Jenkins Hill. Descend once more to Stoke and revisit the Saxton Hockey Pavilion aid station before tackling the Bike Trail ascent again, this time descending through lush forest toward the Roding River and Hacket Carpark. Stock up here — the most rugged section lies ahead. The Hacket Track leads deep into Mount Richmond Forest Park, past the remote Hacket Hut and onto the Te Araroa Trail. For a short stretch you’ll share the path with northbound hikers, navigating steep, technical terrain over Dun Mountain and Little Twin, before descending to Dew Lakes and the Maitai Dam.
From here, link to the Pipeline Trail along the Maitai River before ascending once again to Tantragee Saddle. Enjoy the gradual rise along the Dun Mountain Trail to Third House Hut, cross Coppermine Saddle, then summit Dun Mountain and Little Twin for a second time before returning to the Maitai Dam aid station via Dew Lake.
With the finish line calling, retrace the Pipeline Trail, then face the final push over Tantragee Saddle to the Brook Street Aid Station. One last climb over the imposing Grampians delivers you into a fast, flowing descent into the city. Pass historic treasures like Fairfield and Melrose Houses and the striking Christ Church Cathedral before crossing the finish line on Selwyn Place — the victorious end to a monumental 100-mile journey.
ELEVATION DATA:
Total Ascent: ~6200m

Competitors are required to carry the gear listed in the mandatory gear lists for their event. This contains the minimum gear recommended to keep our athletes safe during The Spectacle. Mandatory gear will be randomly spot checked at the start line and throughout the course. See below for mandatory gear lists.
Trekking poles are permitted for the 10km, 21km, 50km, 100km, and 100 mile races, subject to the following rules:
a. Trekking poles must be fully collapsible so they can either fit inside a running pack or be strapped to the outside of a running pack (and not protrude) when not in use.
b. Trekking poles must always be used in a safe manner so as not to affect the safety of others.Athletes must ensure their bib number is visible at all times on the outside of their clothing and on the front of their body over the abdomen or chest. It must not be worn on pants or legs. Athletes must not cover their bib number with any backpack strap or article of clothing (such as thermal top, waterproof jacket (including see-through jackets) or, if mandatory, a high visibility safety vest. Athletes must not fold, cut or change their bib number in any way. It must be worn as is, unfolded.
Timing chips must be worn on your shoes at all times. If changing shoes during the event, it is up to the athlete to transfer the timing chip to the new shoes.
Headphones are not recommended, but are permitted for all trail races subject to the following rules:
a. Athletes must ensure that using headphones will not impact their mobile phone battery to the extent that the mobile phone will not be able to be of use throughout the entire duration of the race.
b. Athletes must switch off headphones, or lower the volume and use headphones in one ear only, when running on single track so that they can hear communication from other athletes attempting to pass and on any public roads so that they can hear approaching traffic.
c. Athletes must switch off headphones at all aid stations so that instructions from event staff can be heard and followed.
d. Athletes who choose to use headphones must do so in a safe and sensible manner and at a volume which still allows the athlete to remain aware of their surroundings.Athletes must carry all Mandatory Gear specified for their Race Distance on the Race website (and must do so at all times during the Race).
Random gear checks will be performed during the Race. If the athlete is found not to be carrying a mandatory item/s, this could result in disqualification or time penalties.
Refusal to participate in a Mandatory Gear check will also result in disqualification. For on-course gear checks, any time penalty will be served at the location of the gear check so athletes will not be able to proceed on course until the time penalty is served. During this time, the athlete must arrange for the missing item(s) to be replaced or they will not be allowed to continue on course even after the time penalty has been served. Where an athlete is found to be missing any Mandatory Gear items in a subsequent gear check, the athlete may be disqualified. Where it is not feasible to serve a time penalty on course, the time penalty will be added to the athlete’s overall Race time. The time penalty will also be listed within the Race results spreadsheet.Athletes should pay particular attention to any communications received from the Organiser in Race week indicating which weather dependent Mandatory Gear items are required to ensure they are aware of changes to any gear requirements.
MANDATORY GEAR
The mandatory gear list contains the minimum gear recommended to keep our athletes safe during The Spectacle and in Nelson’s unpredictable weather systems, especially while summiting various peaks within the Richmond Ranges. If you would normally take additional gear on a run of this duration and over this terrain, please take it.
The course passes through remote sections of trail, where protection from the elements and medical/support services could be some time/distance from athletes needing assistance. It is therefore imperative that the mandatory gear is carried at all times.
Mandatory gear will be spot-checked before the race and those without the required gear will be unable to compete. Please thoroughly read the mandatory gear list for your race.

The Safety Info.
CUT OFF TIMES
We do not have any mandatory qualification standards. However, the 100 mile is extremely challenging and enters mountainous environments.
To enter you must have adequate fitness, mountain running or hiking experience to complete the course in the available time.
A Race Cut Off: 29 hrs (this start is for those with an estimated finishing time under 30 hrs)
B Race Cut Off: 39 hrs (this start is for those with an estimated finishing time between 30-39 hrs)
START WAVES
We have purposely designed the schedule with two different start times for the 100 mile to allow participants to take on this challenging distance at their own pace. Due to the differing start times and the potential for each group to face different conditions out on the course, results will be recorded and presented as two separate events.
Therefore, if you wish to be eligible for the podium, you must start in the second heat and compete head-to-head, ensuring a level playing field.
It is up to each athlete to determine which start time is appropriate for them.
AID STATIONS
Aid stations will be available on the course. There will be a mix of crewed and field aid stations. You can find more info here when available.
