The Tarawera Ultra-Trail is the best-known trail running event in New Zealand, drawing thousands of local and international runners to the forests, lakes and geothermal country around Rotorua in the Bay of Plenty. Run under the UTMB World Series banner, it offers five distances in 2027 – from an accessible 14 km through to a 163 km mountain miler – so first-timers and seasoned ultra runners line up at the same festival of trail running.
This guide pulls together the practical detail you need to go from entry to finish line: the current distances and dates, how to read the Rotorua terrain, how to train, what gear is mandatory, how to fuel, how to pace, the mistakes that end most days early, and how to recover afterwards. For the course route itself and past winning times, two companion guides go deeper, and both are linked below.

What is the Tarawera Ultra-Trail?
The Tarawera Ultra-Trail is an annual trail ultramarathon staged each February in Rotorua, a geothermal city in New Zealand’s central North Island. An ultramarathon is any running race longer than the standard 42.195 km marathon, and Tarawera spans several of those longer distances on a single race weekend. Courses thread through the Whakarewarewa Forest (the Redwoods), skirt a chain of lakes and cross land of deep cultural significance to local Māori iwi, who welcome runners with a traditional pōwhiri (welcome ceremony).
The event is point-to-point in character: the longer races start inland and finish at the Village Green on Rotorua’s lakefront, where the finish-line festival is held. Because the surfaces range from wide forestry road to rooty lakeside single-track, Tarawera suits runners who enjoy varied, flowing trails rather than steep alpine scrambling.
How the race grew from a local idea
Tarawera began in 2009 as an 85 km race created by Rotorua local Paul Charteris, who had been inspired by time spent near the Western States 100 course in California. That first edition was won by New Zealanders Kerry Suter and Jean Beaumont. Over the following years the event added longer distances, was acquired by The IRONMAN Group, and steadily built a reputation as the country’s flagship ultra. If you are new to the sport, our broader guide to the ultramarathon in New Zealand explains how events like this fit into the wider calendar.
Why UTMB World Series status matters
Tarawera joined the UTMB World Series from its 2023 edition, making it an official qualifying event for the UTMB World Series Finals held each year in Chamonix, at the foot of Mont-Blanc. Finishing a qualifying distance earns Running Stones – lottery tokens used to enter the finals – awarded by race category: one stone for the 20 km-class races (T14 and T21), two for the 50 km-class T50, three for the 100 km-class T102 and four for the 100-mile TMiler. The series status also means an internationally standardised mandatory-gear list and a strong overseas field alongside the Kiwi regulars.
The 2027 distances and how to choose yours
Choosing a distance comes down to your running background, your training consistency and how much time on feet you can realistically commit to. The 2027 event is scheduled for 13–14 February and offers five races, with the long events run on the Saturday and the short T14 on the Sunday. The table below sets out the verified distances, climbing, start times, entry prices and Running Stones so you can match a race to your experience.
Distance Comparison
| Race | Distance | Elevation gain | 2027 start | Entry (NZD) | Running Stones |
|---|---|---|---|---|---|
| T14 | 14 km | 161 m+ | Sun 7:30 am | $160 | 1 |
| T21 | 23 km | 400 m+ | Sat 10:00 am | $195 | 1 |
| T50 | 52 km | 1,150 m+ | Sat 7:00–7:20 am | $445 | 2 |
| T102 | 102 km | 2,300 m+ | Sat 7:00 am | $625 | 3 |
| TMiler | 163 km | 3,800 m+ | Sat 4:00 am | $1,090 | 4 |
The shorter T14 and T21 focus on fast, flowing forest trails and are the natural first step for newcomers. The T50 is a genuine introduction to ultra distance, demanding real pacing and fuelling discipline. The T102 is the historic heart of the weekend and the race most people mean when they talk about “doing Tarawera”, while the 163 km TMiler is an elite-level challenge with a 36-hour limit and a 4:00 am start. For a closer look at how these numbers compare with other events, see our breakdown of ultra marathon distance standards.
Stepping up from the road to the trail
Moving from road marathons to a trail ultra means abandoning your usual pace expectations. Trail times are far slower because of climbing, technical footing and the need to walk steep sections to protect your legs for the back half. Expect to power-hike the hills, eat far more than in a marathon, and think in hours on feet rather than kilometres per minute. A sensible progression is to run a shorter distance one year before stepping up, letting your body adapt to the specific demands of long days on trail.
Understanding the Rotorua terrain
The Tarawera course is often described as faster and more runnable than New Zealand’s rugged alpine races, but that reputation hides a sting: the near-constant short, sharp rollers quietly drain your legs well before the flatter finishing sectors. The region sits on an active geothermal field shaped by the dramatic 1886 eruption of Mount Tarawera, the volcano that gives the event its name (Wikipedia), so underfoot you will meet everything from hard-packed gravel and boardwalk to soft pine needles and slick, rooty lakeside single-track.
Knowing how the surface changes across the race is central to pacing it well. The early forest sections feel cushioned and easy and can lure you into running too hard, while the technical lake tracks later in the day reward short, careful strides. For the full route, elevation and checkpoint layout, our dedicated Tarawera Ultra map guide breaks each distance down section by section.
Reading the underfoot conditions
Each type of trail calls for a different gear and a different mindset. Use the table below to plan where to push and where to conserve.
| Trail element | Typical underfoot conditions | Difficulty | Pacing strategy |
|---|---|---|---|
| Whakarewarewa Redwoods | Soft pine needles, wide smooth tracks, gentle gradients | Low to moderate | Conserve energy, hold a steady rhythm |
| Lakeside single-track | Exposed roots, narrow tread, mud when wet | High | Shorten your stride, focus on foot placement |
| Geothermal pathways | Hard-packed gravel and flat open boardwalk | Low | Keep efficient flat-running form |
| Forestry roads | Clay base, loose gravel, long sustained inclines | Moderate | Power-hike the climbs, control the descents |
How to train for the Tarawera Ultramarathon
Building the engine for Tarawera takes months of consistent, trail-specific work rather than raw road mileage. A common Kiwi mistake is to train almost entirely on flat tarmac, which leaves the quadriceps unprepared for the eccentric load of long descents and causes deep muscle damage in the final quarter. Your plan should prioritise time on feet, climbing and downhill practice over chasing fast splits.
Back-to-back long runs on consecutive weekend days are especially valuable: running on tired legs teaches your body to keep moving and fuelling when fatigued, mimicking the state you will be in late in an ultra. Add regular strength work to protect your knees and hips over many hours of repetitive impact.
Structuring your weekly volume
A balanced week blends easy aerobic running, one hard climbing session, long trail time and targeted strength. The table below shows a workable framework to adapt to your level and chosen distance.
| Session type | Main target | Frequency | Local tip |
|---|---|---|---|
| Aerobic base run | Endurance and fat-burning efficiency | 2–3 per week | Keep it conversational; ignore the watch |
| Hill repeats | Leg strength and climbing power | Once per week | Use a sustained gravel or clay incline |
| Back-to-back long runs | Fatigue resistance and fuelling practice | Fortnightly (weekends) | Wear your full race vest and mandatory kit |
| Functional strength | Core, glute and knee stability | 1–2 per week | Single-leg squats, lunges and calf raises |
Mandatory gear and what to carry
Tarawera enforces a mandatory-gear list on the longer distances because Bay of Plenty weather can swing from humid sunshine under the trees to cold, driving rain across the exposed lakes within an hour. The list exists so that any runner forced to slow or stop in a remote section can stay safe until help arrives. The exact requirements are published on the official site each year and are checked at registration and sometimes on course, so treat the list as non-negotiable.
Typical mandatory items on the longer races include a seam-sealed waterproof jacket with taped seams, a thermal base layer, a hat or beanie, a survival blanket, a basic first-aid kit, a whistle, a headlamp with spare batteries, a cup (the event is cupless at aid stations) and the capacity to carry a set minimum of fluid. Practise running with everything loaded during your peak training weeks to find any chafe points before race day. A well-fitted pack makes this far easier – our guide to choosing a hydration pack for NZ trails covers capacity and fit for exactly this kind of kit.
Shoes, poles and other choices
Trail shoes, not road shoes, are the right tool here: dedicated lug patterns grip muddy clay and wet roots that smooth road soles cannot, cutting your risk of slips and rolled ankles. Look for a shoe that balances grip with enough cushioning for long gravel forestry roads. Poles are permitted and can spare your legs on the TMiler and T102 climbs, but the rules require you to carry them for the whole race if you start with them – you cannot pick them up partway. If you plan to use poles, train with them so your upper body is conditioned to the extra work.
Nutrition and hydration for a long day out
Fuelling is the single most common reason runners fade or withdraw, usually from taking on too much sugar at once or losing too much sodium in the humid forest air. Aim for roughly 60–90 grams of carbohydrate per hour, mixing gels and chews with real food from the aid stations such as salted boiled potatoes, bananas and small sandwiches to keep your stomach settled and stave off flavour fatigue.
Hydration works best as a steady habit rather than occasional big gulps. Sip water and electrolyte fluid every 10–15 minutes so your gut can absorb it without bloating, and lift your salt intake on warm, humid afternoons to head off cramp. The golden rule is to test everything in training: never try a new gel, drink or food for the first time on race day.
Building a hydration schedule that holds up
Plan which aid stations will be your main refill points so you are not carrying unnecessary fluid weight between them, and know roughly how long each leg will take so you leave each station with enough on board. Rehearse the plan on your long weekend runs, in similar heat if you can, and adjust the carbohydrate and sodium amounts until your stomach is happy under sustained effort.
Logistics: drop bags, crew and aid stations
A smooth race day rests on organised logistics. On the longer distances you can send drop bags to designated aid stations, letting solo runners access spare nutrition, dry socks, a fresh headlamp or anti-chafe cream without a physical support crew. Label bags clearly at registration so you can grab what you need and move on quickly rather than losing time rummaging.
If you do have a crew, brief them well: supporting an ultra is its own endurance test of rural driving, parking and hours of waiting in changeable weather. Give them a realistic schedule based on your estimated splits and make sure they carry their own food, warm layers and wet-weather gear. Knowing the checkpoint spacing in advance helps everyone – the T102, for example, runs through eight aid stations between its Kawerau start and the Rotorua finish.
Pacing and race-day execution
The biggest race-day error at Tarawera is starting too fast. The festival atmosphere and flat early kilometres make it easy to burn through glycogen early, triggering a hard crash in the afternoon when the terrain turns technical. Hold yourself back through the first third, keep your breathing easy, and accept being passed early – a patient start lets you reel in fading runners late in the day.
On rolling trails, effort is a better guide than pace. Watching your per-kilometre split is counter-productive when the gradient keeps changing; instead keep your perceived effort or heart rate steady whether you are climbing a clay bank or cruising a gravel road.
Managing effort across the race
Think of the race in quarters and let your effort rise gradually, saving the hardest work for when the finish is in reach.
| Race phase | Target effort (1–10) | Tactical focus | Pitfall to avoid |
|---|---|---|---|
| First quarter | 4–5 (very comfortable) | Settle in, start fuelling early | Getting dragged along by the crowd |
| Second quarter | 5–6 (controlled) | Efficient movement, steady power-hiking | Neglecting hydration as it warms up |
| Third quarter | 7–8 (challenging) | Focus through technical trail, manage the mind | Letting self-doubt slow you down |
| Final quarter | 8–10 (maximum) | Empty the tank, short strides to the line | Long rests at the final aid stations |
Common mistakes runners make at Tarawera
Most did-not-finish stories trace back to a handful of avoidable errors rather than bad luck. Knowing them in advance is half the defence.
- Going out too hard: the flat opening lulls runners into a marathon pace that is unsustainable over ultra distance and terrain.
- Under-fuelling early: waiting until you feel hungry or flat is too late; start eating within the first hour and keep it steady.
- Trying new gear or food on the day: untested shoes, packs, gels or drinks are the classic cause of blisters and stomach trouble.
- Ignoring the mandatory list: skipping required kit risks disqualification and real danger if the weather turns.
- Dwelling at aid stations: several ten-minute stops add up to an hour lost and let your muscles stiffen.
- Fearing the low patch: expecting a dark stretch and breaking the course into small milestones gets you through it far better than panic.
Recovery after the race
Crossing the line is not the end of the job; a structured recovery protects the immune and digestive systems that an ultra leaves depleted. Change into dry, warm clothing straight away to stop your core temperature dropping, then take on a drink with both carbohydrate and protein to kick-start muscle repair even if your appetite is low. In the days that follow, prioritise sleep, gentle movement such as walking or easy swimming, and nutrient-dense whole foods.
Resist the urge to rush back into hard training. Returning before residual soreness has fully cleared raises the risk of overuse injury and overtraining. Most runners need at least a couple of weeks of easy movement before their first short, relaxed trail jog, and longer after the T102 or TMiler.
Who the Tarawera Ultra suits
Tarawera suits a wide range of runners precisely because it offers five distances on one weekend. The T14 and T21 welcome trail newcomers and road runners curious about off-road racing; the T50 fits a first-time ultra runner with a solid training base; and the T102 and TMiler reward experienced ultra athletes who have practised night running, fuelling and self-sufficiency. Its relatively runnable profile and strong aid-station network also make it a friendlier first big ultra than many alpine events. If you are weighing it against other local options, the nearby Taupō Ultramarathon and the city’s own Rotorua Marathon make useful comparisons, and the past Tarawera Ultra results show the spread of finishing times from the front of the field to the final cut-off.

Frequently Asked Questions (FAQ)
When and where is the 2027 Tarawera Ultra-Trail?
The 2027 event runs on 13–14 February in Rotorua, in New Zealand’s Bay of Plenty. The long distances (TMiler, T102, T50 and T21) are held on the Saturday and the shorter T14 on the Sunday, with the main finish-line festival at the Village Green on Rotorua’s lakefront.
What distances does the Tarawera Ultra offer?
In 2027 there are five races: the T14 (14 km), T21 (23 km), T50 (52 km), T102 (102 km) and the TMiler (163 km). Climbing ranges from about 161 m on the T14 to roughly 3,800 m on the TMiler, so there is a step for almost every level of trail runner.
Do I need trail shoes, or will road shoes do?
Trail shoes are strongly recommended. While some forestry roads are smooth and firm, the lakeside single-track has exposed roots and mud where road soles lack grip and protection, raising the risk of slipping or turning an ankle. Dedicated trail lugs give the traction the course demands.
How do the UTMB Running Stones work at Tarawera?
As a UTMB World Series event, finishing a qualifying race earns Running Stones used as lottery entries for the UTMB World Series Finals in Chamonix. Stones are awarded by category: one for the T14 and T21, two for the T50, three for the T102 and four for the TMiler.
What mandatory gear do I have to carry?
The longer races require items such as a seam-sealed waterproof jacket, a thermal layer, a beanie, a survival blanket, a first-aid kit, a whistle, a headlamp with spare batteries, a reusable cup and a minimum fluid capacity. The official list is confirmed each year and checked at registration, so carry everything specified for your distance.
