Pacing the Auckland Marathon: How to Master the First Half
The Auckland Marathon is a race of two halves. A hilly, deceptive opening followed by a flat and fast run home. In 2019, I ran my personal best here by pacing those early kilometres with patience and precision. In this post, I share practical pacing strategies, key course insights, and fueling tips to help you master the first half, and set yourself up for a strong finish.
It’s 4:30 a.m. on race morning and the ferry is humming across the harbour, packed with quiet, nervous runners. Everyone’s clutching coffee cups or sipping on carbohydrate drinks, quiet whispers as they shuffle for space. The city skyline glows behind, while out front, the North Shore awaits...dark, hilly, and full of potential pitfalls.
This is what makes Auckland unique. Before you’ve even crossed the start line, your day has already been shaped by preparation. The early alarm, the pre-dawn breakfast, the ferry ride across to Devonport. It sets the tone. Auckland rewards planning, patience, and discipline.
I learned that lesson well in 2019, when I ran my personal best of 2:35 here. That race remains one of my most satisfying marathons, not because of a finishing sprint or a dramatic negative split, but because I nailed the pacing strategy over those crucial opening kilometres.
The Big Race Feel
Auckland has something that no other New Zealand road marathon quite matches and that is scale. The start line has that big-race hum, the roads are closed, the crowd support builds as you cross the bridge, and the final stretch along the waterfront and into the city has genuine atmosphere. It’s a race that feels bigger than its size, and that energy can pull you along, for better or worse.
Where you stay matters too. Most runners stay in the city and take the ferry over in the morning, which adds a layer of excitement (and early logistics). Personally, I like that ritual. It sets the day apart and makes it feel like a calm before the storm that builds anticipation.
Why the First Half Matters So Much
The Auckland Marathon is a race of two distinct halves. The second half is flat and fast, a scenic out-and-back along the waterfront however the first half is deceptive. From the start at Devonport through to the Harbour Bridge, the course rolls constantly. They’re not “big” hills, but they’re relentless enough to punish anyone who tries to hold goal pace from the gun.
In a marathon, early overexertion doesn’t show up straight away. It shows up at 30 km, when your legs suddenly stop responding. That’s why your pacing decisions in the first 10 kilometres are so important, even more-so at Auckland.
The Plan: Control Early, Cash In Later
In 2019, I lined up with my mates Chris and Ben. We’d trained together all through the winter. A lot of cold early mornings, long Sunday runs, and plenty of K-Park fierce laps. By the time race day rolled around, we were in sync and ready. Chris had a secret weapon, local knowledge. He grew up in Takapuna and knew every rise, dip and camber on those North Shore roads. In our final weeks, he kept repeating the same message, “Don’t get greedy early.”
That became the backbone of our strategy. The first 10 kilometres of Auckland are where discipline pays off. The terrain is rolling, energy is high, and you’ve just spent the morning on a ferry with hundreds of other jittery runners. It’s incredibly easy to run the first few kilometres too hard and ruin your race althogether.. The damage this does doesn’t show up right away. It creeps in around 30 km when your legs suddenly stop responding.
Our goal wasn’t to jog the early stages, it was to run with control, not caution. That meant respecting the undulations, backing off on the climbs, and letting the pace flow naturally on the flats and gentle descents. We wanted to find a rhythm that felt comfortable but measured, so we’d have something left to work with after the Harbour Bridge.
If you’re racing Auckland, think about this first section as an investment window, not a test. One practical way to apply this is to allow yourself to run 5–10 seconds per kilometre slower than goal pace over the first 5 km, especially on the climbs. Keep your breathing under control, hold back on any surges, and resist the urge to “bank time.” As the course flattens out, you’ll be able to gradually settle into race rhythm without carrying lactic debt into the second half. This is where patience turns into free speed later.
My numbers tell the story. We deliberately gave away time in the opening 5 km, then earned it back effortlessly in the next 10 km as the course dipped down and flattened out. It wasn’t forced, our legs simply had more to give because we hadn’t burned our matches too early.
I see this mistake often as a coach...runners lock into goal pace from the gun, even when the course or conditions demand otherwise. They chase the number on their watch instead of tuning into effort. In Auckland, that’s a huge trap. If you try to hit your goal pace over every roller in those early kilometres, you’ll pay for it later. If you can keep your ego in check and run the opening section a touch within yourself, the flat stretch after 10 km becomes a launchpad and not a rescue mission.
Know the Key Climbs
Hayden Shearman wrote a brilliant breakdown of the Hills of the Auckland Marathon. It’s definitely worth reading in full, but a few climbs stand out from both his analysis and my own race data:
Around 3 K: There’s a long, steady rise at what Hayden calls Hill #4. It’s about a kilometre long, and it’s where I ran 13 seconds slower than my race average. That’s not a failure, that’s smart pacing. If you attack this hill, you’ll pay for it later.
The Harbour Bridge (15 K): By the time you hit the motorway, you’ve had a few kilometres of flat running. Then the bridge looms. It’s always steeper and longer than you remember from the car. I ran a 4:00 split for that kilometre, over 20 seconds off average pace, and that was entirely intentional. The key is to stay within yourself, focus on effort rather than pace, and avoid spiking your heart rate
The Shelly Bay Pincher: Just after you descend the bridge, there’s a short, sharp climb on Shelly Bay Road (around 20 m of gain). It hits tired legs unexpectedly. Don’t let it catch you off guard.
Respect the Downhills
One of the easiest ways to ruin your legs is to hammer the downhills trying to “make up time.” The reality is, you never get the full benefit back. It’s like wind...a tailwind never fully cancels out the work you did into a headwind.
In Auckland, the descent off the bridge is particularly dangerous for the quads. Treat the downhills as aerobic recovery, not opportunities to bank seconds. Keep your stride smooth, stay relaxed, and let gravity do the work without forcing it.
Fueling: Get It Right, Reap the Rewards
Pacing is only part of the Auckland Marathon equation, fueling is the other half. As Auckland starts very early, it's vital that you wake up early enough to get a good breakfast in and allow time for digestion.
Your body has limited glycogen stores, and at marathon intensity those reserves can run low after 60–90 minutes. Research indicates that when your glycogen stores drop below 50%, performance decreases dramatically. If you’re not topping up early and consistently, even the best pacing plan can unravel in the final 10 km
Most reputable guidelines recommend taking in around 30–60 g of carbohydrate per hour for the average runner, and up to 60–90 g per hour for faster or more experienced athletes but only if you’ve trained your gut to handle it. The key is to work out what’s right for your body, then practise that strategy well before race day.
In my own marathons, the turning point came when I started calculating exactly how much carbohydrate I needed, rather than guessing. I broke my race into 30-minute segments and included the 30mins just prior to the gun. I used a mix of Maurten high-carb drink and gels, and treated fueling like another key part of my race plan, not an afterthought.
A good starting point for most is to:
Eat a carb-rich breakfast 2–3 hours before the race (1–4 g/kg body weight depending on timing).
Start fueling early, within the first 30 minutes of the race.
Aim for a steady intake, delivered in small, regular doses (e.g. a gel every 30 mins plus sips of drink in between).
Practise this during your long runs so your gut and pacing plan are in sync.
Fueling isn’t glamorous, but it’s decisive. Get it right, and you give yourself the best possible platform to hold your pace and finish strong.
Final Thoughts
The Auckland Marathon rewards smart runners. The first half isn’t about hitting perfect splits. It’s about controlling effort, respecting the course, and setting yourself up for the flat, fast run home from St Heliers.
Start conservatively, stay smooth over the hills, fuel early and consistently, and resist the urge to chase time on the downhills. If you do, you give yourself the best chance to finish strong.
For me, that strategy turned 2019 into a career-best day. For you, it might be the difference between hanging on in the final 10 K…or flying home down the waterfront.
