Marathon Pace Chart

Find your goal pace. Understand your splits. Run a smarter marathon.

Every pace chart gives you numbers. This one explains why they work — and gives you the tools to use them on race day. Find your finish time in the chart below, toggle between even and negative splits, and download a personalized chart to take with you. Then keep reading for the pacing strategy behind it.

How to Use This Chart

The chart works three ways.

Browse the reference table. Every goal finish time from 1:45 to 7:00 is listed with per-mile and per-km pace and key split checkpoints. No goal time entered? You still get everything you need to reference on race day.

Enter your goal time. Your row highlights, a detailed split breakdown appears below the table, and you can toggle between even and negative split strategies to see how each plays out across your race.

Download your splits. Once you’ve entered your goal time, grab a personalized PDF to carry on race day. If you’d like it sent to your inbox, just enter your email.

Even Splits or Negative Splits? The McMillan Approach

Most runners know they shouldn’t go out too fast. Fewer understand exactly why — or how much it costs them.

Pacing is an energy management and muscle protection problem. Your glycogen stores are finite. The faster you run early, the faster you burn through them — and the interest rate on that debt compounds the longer the race goes on. Going out too hard in mile 6 doesn’t just slow you down at mile 22. It can end your race entirely. And running fast for long periods causes microtears in the muscle fibers. Run too fast too early and fatigue-causing muscle damage is accelerated.

Even splits — holding identical pace from start to finish — is energetically efficient and achievable. On a flat course with good conditions, a well-executed even split produces a strong time. It’s a perfectly valid strategy, and it’s what many runners should aim for until they have enough race experience to feel confident managing effort over 26.2 miles.

My preference for most marathon courses, and what the data from elite performances and world records consistently shows, is a slight negative split: run the second half of the marathon a few seconds per mile faster than the first. Not dramatically faster. The difference is almost invisible early in the race — it’s patience, not slowness. What it buys you is a finishing surge when every other runner around you is fading.

Here’s how I think about it: your body is an engine, and every engine has an optimal RPM range. In a marathon, that range is narrower than most runners realize. Push above it early — even slightly — and you’re burning fuel you can’t replace and fatiguing your legs. Stay in range through 20 miles and you’ll have something left when it counts.

The runners who come through the second half strong aren’t a different breed. They’re the ones who resisted the crowd at mile 1 and trusted the plan.

Use the even/negative split toggle in the chart above to see exactly what this looks like for your goal time. Run the numbers. The difference between the two strategies — and when it matters — becomes very clear.

What Actually Determines Marathon Success

A lot of runners train hard for cardiovascular fitness and wonder why they still hit the wall. The truth is that marathons aren’t primarily won or lost in your lungs — they’re determined by your legs, your fueling, your brain, and how well you protect all three with smart pacing. Here’s what I focus on with every marathon athlete I coach.

Leg Durability

The average marathoner takes 35,000 to 45,000 steps during the race. That’s not a cardiovascular event — it’s a structural one. Runners with excellent aerobic fitness still hit the wall when their legs can’t absorb the pounding of the final miles. Building legs that hold their form and efficiency through mile 26 is the first priority in any smart marathon plan, and it’s why my training programs emphasize consistent mileage, long runs, and dedicated leg strengthening work like the Marathon Legs program.

Fueling

Your blood glucose (aka sugar) levels and your carbohydrate stores — glycogen — begin depleting after roughly two hours of running at marathon pace. Eliud Kipchoge finishes in under two hours. Most of us take considerably longer. That means fueling during the race isn’t optional, and it can’t be improvised on race day. You need a strategy you’ve practiced in training until it’s automatic. Here’s my guide to marathon fueling to help you build that plan.

Brain Training

Your brain monitors everything — heart rate, temperature, muscle fatigue, energy availability. When it detects too much stress, it responds by amplifying fatigue signals and, in extreme cases, reducing power to your working muscles to protect you. The irony is that the brain responds to perceived threat, not just actual damage. Train it right and your brain becomes an ally. Train it wrong — by going out too fast, skipping long runs, or neglecting race-specific suffering — and it becomes the thing that makes you walk at mile 20 (km 32).

My fast finish long runs are specifically designed to expose the brain, in small doses, to the fatigue it will face in the race. By the time you reach the start line, the suffering isn’t a surprise — it’s familiar territory.

Proper Pacing

We covered this in depth above. The short version: even splits or a slight negative split, executed with discipline and patience in the first half. Something many runners are surprised to discover is that later in the marathon, you have to ramp up your mental intensity considerably just to maintain pace — not to run faster. That’s the nature of the distance. My Go Zone Racing strategy is built specifically to prepare you for that mental shift.

Train for Your Marathon Goal

Knowing your goal pace is the starting point. Getting there is a different project — one built around your current fitness, your runner type, and a plan that fits your life.

My marathon training plans are available on Final Surge and TrainingPeaks at three levels — novice, intermediate, and advanced — and across different runner types: speedsters, combo runners, and endurance monsters. There are also specialty plans built for major marathons like Boston, New York, London, Tokyo, Berlin, Sydney and Chicago.

If you want coaching alongside your plan, Run Team gives you your training plan, prehab routines, weekly check-in emails, and direct access to ask questions as you train. Try it free for 14 days — no commitment required.

If you have more than three months until race day, consider starting with preparatory training. A prep block builds the aerobic base and leg durability that make the marathon plan more effective — and dramatically reduces the injury risk that derails so many training cycles before they ever reach the start line.
