The Emerson’s Dunedin Marathon is New Zealand’s great southern road race, run each spring around the sheltered waters of Otago Harbour and finishing in the heart of the city beside the Emerson’s brewery. First held in 1979, it is one of the oldest and most scenic marathons in the country, and the 2026 edition — the 46th running — takes place on Sunday 13 September 2026, with the full marathon starting at 7:00am.
This guide covers everything you need to plan your race: where the course actually starts and finishes, how the harbour-side route runs, the distances on offer and their entry fees, and practical advice on training, gear, fuelling, pacing and recovery for Dunedin’s changeable late-winter conditions. Whether you are stepping up to your first 42.2km or walking the 5km with family, the facts below will help you line up relaxed and well prepared.

What is the Emerson’s Dunedin Marathon?
The Emerson’s Dunedin Marathon is an annual road-running and walking festival held in Dunedin, on the South Island’s southeast coast. It began in 1979 and has grown into a multi-distance event that now draws runners from Christchurch, Invercargill, Auckland and overseas, alongside a strong local Otago field. The 2026 event is the 46th edition and is title-sponsored by Emerson’s, the Dunedin brewery next to the finish line.
The full marathon course is AIMS-certified, which means it has been measured to the international standard used for record-eligible and qualifying races. In practice that lets you use a Dunedin finish time to qualify for events such as the Boston Marathon, provided you hit the relevant qualifying standard. It is one of only a handful of certified mainland South Island marathons, which is a large part of its appeal to time-chasing runners.
Why the race carries a brewery’s name
Emerson’s is the naming sponsor, and the race deliberately finishes right outside the brewery on the edge of central Dunedin, turning a hard day into a celebration. This is the single most important correction to make if you have read older guides: the Dunedin Marathon does not finish inside or beside the Forsyth Barr Stadium. Every distance finishes by crossing a railway bridge and heading down the Ward Street ramp to the brewery forecourt near the Steamer Basin. The stadium sits nearby in the same Logan Park precinct — a venue better known for rugby, including sevens (Wikipedia) — but it is not the finish line.
The Dunedin Marathon course explained
The marathon is essentially an out-and-back along the western shore of the Otago Peninsula, tracing the flat, sheltered edge of Otago Harbour. Runners head northeast out of the city along Portobello Road and the harbour-side shared path, turn around near the far end of the peninsula between Penguin Place and Te Rauone Reserve, and then retrace the water’s edge back toward the central city to finish at Emerson’s. The route is almost entirely sealed road and paved shared path, with no alpine climbs — its defining challenge is exposure to the elements rather than hills.
Where each distance starts and finishes
The start arrangements are simpler than many older descriptions suggest, and getting them right matters for your race-morning plan. The full marathon has its own start at Portobello Recreation Reserve, roughly halfway along the peninsula, so that the out-and-back measures the full 42.2km back to the brewery. Every other distance — the half marathon run, the half marathon walk, the 10km run, the 10km walk and the 5km fun run and walk — starts together in the city at Caledonian Ground on Logan Park Drive. All distances share the same finish line beside Emerson’s Brewery.
What the harbour route feels like underfoot
Because the course hugs the water, the surface and the wind change more than the gradient does. The table below breaks the route into the sections you will notice on the day and the tactical focus each one rewards.
| Route sector | Dominant surface | Wind exposure | Tactical focus |
|---|---|---|---|
| Peninsula roadway (Portobello Road) | Older sealed road with slight camber | High, with harbour crosswinds | Keep your stride compact and run the flattest line |
| Harbour shared path | Modern flat asphalt and concrete | Exposed to the water | Stay light-footed; avoid over-striding on hard concrete |
| City approach to Emerson’s | Flat urban streets, railway bridge and ramp | Low, more sheltered | Lift your cadence, stand tall and drive to the line |
Distances and how to choose one
The Dunedin Marathon runs six timed events over the Sunday, so there is a sensible option whether you are a seasoned marathoner or a first-time walker. A separate ASB George Street Mile programme — kids’, social, university and the NZ Mile Championships — is held in the city centre on the Saturday before, making it an easy two-day weekend for families and clubs.
Distance Comparison
| Event | Distance | Start | Best suited to | 2026 entry (NZ$, early–late) |
|---|---|---|---|---|
| Full marathon | 42.2 km | Portobello Reserve | Experienced endurance runners; Boston qualifiers | ~$110–150 |
| Half marathon run | 21.1 km | Caledonian Ground | Regular runners and goal-race seekers | ~$80–120 |
| Half marathon walk | 21.1 km | Caledonian Ground | Committed walkers building distance | ~$70–110 |
| 10 km run | 10 km | Caledonian Ground | Newer runners and stepping-stone goals | ~$65–100 |
| 10 km walk | 10 km | Caledonian Ground | Walkers wanting a full finish experience | ~$50–90 |
| 5 km fun run & walk | 5 km | Caledonian Ground | Families, children and first-timers | ~$25–60 |
Stepping up to a longer distance
Move up a distance only when your training load genuinely supports it, not on race-week enthusiasm. The jump from the half marathon to the full is the biggest single step: the flat harbour course removes the excuse of hills, which means there is nowhere to hide if your long-run endurance is not there. A good rule of thumb is to have comfortably run at least 30km in a single training session, and to have logged several weeks of consistent mileage, before you commit to the 42.2km. Walkers moving from 10km to the half should build their time-on-feet the same way runners build distance.
- 5km fun run and walk — the most accessible option, ideal for children, beginners and anyone wanting the finish-line atmosphere without a big build-up.
- 10km run or walk — a popular stepping stone that still delivers harbour views and a proper finisher’s experience.
- Half marathon run or walk — a strong goal race in its own right and a logical bridge toward the full distance.
- Full marathon — the 42.2km out-and-back along the peninsula, and the only AIMS-certified option.
Entry fees and how to enter
Entries are handled online through the official event site, with pricing that rises in three tiers as race day approaches — early bird, standard and late — so entering early is the cheapest way in. For 2026 the full marathon ran from about NZ$110 early bird to NZ$150 late, the half marathon run from roughly NZ$80 to NZ$120, the 10km run from about NZ$65 to NZ$100, and the 5km from around NZ$25 to NZ$60; the recreational walk categories sit a little below their running equivalents, and children 11 and under receive a discount on the 5km. Always confirm the current tier and closing dates on the official site before you commit, as prices and cut-off dates are set each season.
If you are weighing Dunedin against other southern options, it slots naturally between the fast, flat Christchurch Marathon and the scenic, hillier Queenstown Marathon, and our overview of New Zealand’s major marathons compares dates and terrain side by side.
Training for a flat harbour marathon
Training for Dunedin rewards consistency and time-on-feet more than raw speed, because the course asks you to hold a steady effort for hours against wind rather than to attack climbs. A common mistake among road runners is to do all of their preparation on flat treadmills or wind-free indoor tracks, which leaves the legs underprepared for the gentle rollers and the open, exposed harbour edge. Spend your long runs outdoors, ideally on roads and paths that mimic the race surface, and in weather you might actually meet on the day.
A balanced training week
A reliable weekly structure blends easy aerobic running, one quality session, a weekend long run and genuine recovery. This mix lets your tendons, joints and connective tissue adapt between hard efforts, which is what keeps you healthy through a long build.
| Session type | Main purpose | Frequency | Practical tip |
|---|---|---|---|
| Easy conversational run | Builds aerobic base and efficiency | 2–3 times per week | Hold a pace at which you can speak in full sentences |
| Tempo or steady session | Lifts your sustainable race pace | Once per week | Run a rolling road to rehearse holding effort into a breeze |
| Weekend long run | Builds endurance and mental resilience | Once per week | Wear your exact race-day shoes and test your fuelling |
| Mobility and rest | Allows repair and reduces injury risk | 2–3 days per week | Add core, calf and glute work plus quality sleep |
A marathon pace chart is worth building into your long runs so you rehearse your target splits rather than guessing, and if the half is your goal the same logic applies to the half marathon distance.
Weather and gear for Dunedin’s spring
Mid-September in Dunedin can swing from a crisp, frosty start to bright sun within a couple of hours, and a cool breeze can come off the harbour at any time. Dress in versatile, moisture-wicking layers rather than a single heavy top, and avoid cotton completely, because it holds sweat against your skin and chills you fast once the wind picks up. A packable wind layer is sensible if the forecast looks unsettled.
Footwear is your most important choice. The course is entirely sealed road and paved path, so a well-cushioned road shoe is ideal; aggressive trail shoes with deep lugs are unnecessary and feel heavy over long, hard stretches. Break your shoes in with at least several training runs beforehand, and never wear brand-new socks on the morning of the event. Reliable kit such as technical running socks can be the difference between a comfortable finish and a blistered one.
Fuelling and hydration on course
A well-tested nutrition plan matters as much as your mileage. Running for several hours drains the glycogen stored in your liver and muscles, so you need to take on carbohydrate during the race to hold your blood-glucose steady. Most endurance runners aim for roughly 60–90 grams of carbohydrate per hour from gels, chews or sports drink — but only use products you have rehearsed in training, never something new on race morning.
Drink to a plan rather than waiting until you are thirsty. Take regular, controlled sips at the on-course drink stations from early on, which lets your stomach absorb fluid steadily without bloating. Slowing to a brief walk through a station makes it far easier to swallow cleanly. On an unusually warm day, salt or electrolyte capsules can help stave off cramp.
Pacing the out-and-back harbour course
The flat profile makes it dangerously easy to start too fast, so a disciplined, even effort is the key to a strong finish. Split your race mentally into three phases: a controlled, comfortable opening; a steady rhythmic middle where you settle onto goal pace; and a progressive push home over the final kilometres. On an out-and-back you will quickly learn which direction the wind favours — bank a little effort while it is at your back and run the sheltered line into a headwind rather than fighting it.
| Race phase | Portion of course | Target effort (1–10) | Mindset |
|---|---|---|---|
| Opening | 0–25% | 4–5, very comfortable | Find clear space, settle your breathing and resist the early surge |
| Middle | 25–75% | 6–7, steady and rhythmic | Lock onto goal pace; stay relaxed through the crosswinds |
| Final push | 75–100% | 8–10, strong and focused | Lift your cadence and drive down the ramp to Emerson’s |
Race-day logistics
Because the marathon starts out on the peninsula at Portobello while the shorter events start in the city at Caledonian Ground, plan your morning around your specific start. Arrive at your assembly area in good time — at least 45 minutes before your start is sensible — so you can collect yourself, warm up gently and use the facilities without rushing. Check your timing chip is secure before you travel to the start, and carry a throwaway warm layer you can discard once you get moving.
The organisers run a drop-bag service so you can send a bag of warm, dry clothing from the start to the finish village at Emerson’s. Confirm the bag cut-off and collection details in your race information when you register, and label your bag clearly with your bib number so it is easy to find in the finish area.
Common mistakes to avoid at Dunedin
Most problems on the day come from preparation, not fitness, and they are easy to pre-empt once you know the course.
- Expecting a stadium finish. Plan your meeting point and bag collection around Emerson’s Brewery and the Ward Street ramp, not Forsyth Barr Stadium.
- Going out too hard. The flat, fast start tempts runners into a pace they cannot hold once the wind and distance bite later.
- Underdressing — or overdressing. A frosty start does not mean the whole race is cold; use layers you can shed rather than one heavy top.
- Training only on flat, sheltered routes. You need to have run in wind and on open roads to pace the harbour edge confidently.
- Trying new fuel or shoes on race day. Rehearse everything — gels, drinks, socks and shoes — on your long runs first.
After the finish
Crossing the line at Emerson’s is a genuine celebration, but look after yourself before you relax. Keep walking gently for a few minutes rather than stopping dead, which helps your heart rate settle and reduces stiffness. Change into dry, warm clothing quickly, because your core temperature drops fast in the southern air once you stop moving. Rehydrate with water or an electrolyte drink and eat a carbohydrate-and-protein snack to kick-start recovery before you enjoy anything from the brewery. Give your legs several easy days afterwards before returning to hard training. If you have caught the southern bug, the broader New Zealand running calendar will help you line up your next goal race.

Frequently Asked Questions (FAQ)
When is the Emerson’s Dunedin Marathon 2026 and where does it finish?
The 2026 event is held on Sunday 13 September 2026, with the full marathon starting at 7:00am. Every distance finishes in the central city by Emerson’s Brewery, reached by crossing a railway bridge and running down the Ward Street ramp — not at Forsyth Barr Stadium, as some older descriptions suggest.
What does the marathon course look like?
The marathon is an out-and-back along the sheltered western shore of Otago Harbour. It starts at Portobello Recreation Reserve, heads northeast up the peninsula along Portobello Road and the harbour shared path, turns around near Penguin Place and Te Rauone Reserve, and returns to the city. It is flat, sealed and paved throughout, and AIMS-certified.
What distances can I enter and where do they start?
There are six timed events: a full marathon, a half marathon run and walk, a 10km run and walk, and a 5km fun run and walk. The full marathon starts at Portobello Recreation Reserve, while all the other distances start together at Caledonian Ground on Logan Park Drive. A separate George Street Mile programme runs in the city on the Saturday.
What shoes and clothing should I wear?
Because the whole course is sealed road and concrete path, a well-cushioned road running shoe is the best choice; trail shoes are unnecessary. Dress in versatile, moisture-wicking layers you can shed, avoid cotton, and pack a light wind layer. Mid-September weather can move from a frosty start to sun and a cool harbour breeze within the morning.
How much does it cost and how do I enter?
Entry is online through the official event site and is tiered — early bird, standard and late — so entering early is cheapest. In 2026 the full marathon ranged from roughly NZ$110 to NZ$150, with the half, 10km and 5km priced progressively lower, and walk categories a little below their run equivalents. Confirm the current tier and closing dates before you commit, as pricing is set each season.
