How fast should you run during marathon training?

It depends on the purpose of the run.

One of the most common mistakes marathoners make is trying to run too fast on ordinary days. An easy run starts feeling good, so they speed up. A steady run turns into a workout. Warmups, cooldowns, and recovery runs get pushed too hard. Over time, that creates unnecessary fatigue and makes it harder to run your workouts and long runs well.

Every run should have a purpose. Some runs should be easy. Some should be moderate. Some should be fast. Some should be race-specific. The key is to run each day at the intensity that matches the goal of the run.

Quick Answer: How Fast Should You Run Each Day?

Most of your marathon training should be relatively comfortable, with smaller amounts of faster running layered in intentionally throughout the week and throughout the training cycle.

Easy days should usually feel easy. Faster running should be saved for workouts, long runs with a purpose, and race-specific training. Going faster on a run that is supposed to be easy does not automatically make it better.

In this video, I explain how the different training paces fit together and why running faster does not automatically make your training better.

The Biggest Marathon Training Pace Mistake

The biggest mistake is spending too much of your training in the middle.

You are not really running easy, but you are not running hard enough to get the full benefit of a workout either. I sometimes think of this as running “fast-ish.”

That kind of running can feel productive because you finish the run knowing you worked, but it often creates extra fatigue without accomplishing as much as either truly easy running or a deliberately structured workout.

The correct pace is the pace that matches the goal of the run.

Pace and Intensity Chart

This is the basic framework I use to think about training intensity. Each pace has a different role in marathon training.

Perceived Effort Level	Name of Pace	Specific Training Focus
10	Sprint / Finishing Kick	Improves running form + top speed
9	1-Mile Pace	Improves running form + top speed
8	5K Pace	Speed development for marathon
7	10K Pace	Speed development for marathon
6	Half Marathon Pace	Speed + specific endurance for marathon
5	Marathon Pace	Specific endurance for marathon
4	Long Run Pace	General endurance for marathon
3	Easy Pace	Aerobic and musculoskeletal strength
2	Recovery Pace / Jog	Aerobic and musculoskeletal strength
1	Walk	Aerobic and musculoskeletal strength

Marathon Pace vs. Everyday Pace

One of the most important concepts for marathoners to understand is that your everyday running pace should usually be slower than marathon pace.

Running too fast on easy days, warmups, cooldowns, and recovery runs is one of the most common mistakes runners make. Easy running should help you build aerobic fitness and stay consistent while recovering from your harder training.

Below is a useful rule-of-thumb chart. It is not a rigid law, but it gives a practical starting point for how marathon pace and everyday pace often relate.

Goal Finish Time	Marathon Pace	Everyday Pace
2:30:00	5:42	6:35 ~ 7:15
2:45:00	6:15	7:15 ~ 8:00
3:00:00	6:50	7:50 ~ 8:40
3:15:00	7:25	8:25 ~ 9:20
3:30:00	8:00	9:00 ~ 10:00
3:45:00	8:33	9:40 ~ 10:40
4:00:00	9:05	10:10 ~ 11:15
4:15:00	9:43	10:35 ~ 11:40
4:30:00	10:15	10:55 ~ 12:00
4:45:00	10:50	11:15 ~ 12:25

There are always exceptions. Terrain, heat, humidity, accumulated fatigue, and individual ability can all affect where your appropriate easy pace falls. But for many marathoners, the big takeaway is simple:

Do not try to run your easy days anywhere close to marathon pace.

How Fast Should You Run Throughout the Week?

This chart shows the difference between how many runners think they get faster and how they actually get faster.

How most people think you get faster…
Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
Off	75% Hardish Run	Off	75% Hardish Run	Off	60 to 75% Hardish Long	Off

How you actually get faster!
Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
Off	80% Speed	30% Recovery	70% Tempo	Off	40 to 50% Specific Long	30% Recovery

The message here is not that every runner should follow this exact weekly schedule. The message is that improvement usually comes from variety, structure, and appropriate pacing, not from hammering moderately hard every day.

Easy Pace

Easy running should feel comfortable and conversational. You should be able to breathe under control and finish the run feeling like you could have kept going.

Easy runs help you build aerobic fitness, support your mileage, and recover from harder sessions. These runs are not meant to prove your fitness. They are meant to support your fitness.

Easy pace is especially important during base building, when the goal is to establish consistent volume and develop your aerobic foundation.

Long Run Pace

Long run pace usually sits a little quicker than easy pace but should still be controlled unless the long run has a specific workout built into it.

Some long runs are purely aerobic. Others become marathon-specific over time. The appropriate pace depends on the goal of the session and the phase of training you are in.

If you want to understand how all of these efforts fit together, my article on The Pyramid of Marathon Training is a good companion to this one.

Marathon Pace

Marathon pace is the pace you are preparing to sustain for 26.2 miles. It should be based on your current fitness, not just on your dream goal time.

During shorter marathon-pace workouts, this pace should feel controlled. During longer race-specific workouts, it becomes more demanding, which is part of what makes marathon-specific training so useful.

Marathon pace becomes a bigger focus during the race-specific quality phase of marathon training.

Half Marathon Pace, 10K Pace, and 5K Pace

These faster efforts help develop the speed, strength, and efficiency that eventually support your marathon performance.

Half marathon pace often blends speed with specific endurance. 10K and 5K pace are commonly used for speed development and faster aerobic work. The faster the pace, the more important it is that the workout be structured and intentional rather than something you stumble into accidentally during a normal run.

That is why I typically place a greater emphasis on these faster paces during the speed development phase.

You Do Not Need Every Pace Every Week

One of the most important things to understand is that you do not need to force every pace category into every week of training.

Your emphasis should change throughout the training cycle. The six-phase framework I use looks like this:

1. Base Building
2. Speed Development
3. Race-Specific Quality
4. Taper
5. Race Day
6. Recovery

You may emphasize easy mileage and strides during base building, faster repetitions during speed development, and longer marathon-pace work as your race approaches. The paces remain available, but their importance changes depending on the phase.

For a full overview, read The Six Phases of Marathon Training.

Why Most of Your Running Should Be Relatively Easy

Most marathoners improve best when most of their training is performed at lower intensities, with smaller doses of faster running added strategically.

This allows you to build more aerobic volume, recover better, and perform your quality sessions more effectively.

A recent study looking at the training of more than 150,000 marathon performances found that faster runners accumulated more low-intensity running and that a pyramidal intensity distribution was very common among stronger marathoners. A systematic review of middle- and long-distance runners has also supported the broad idea that high volumes of low-intensity training combined with smaller amounts of threshold and high-intensity work tends to work very well.

Common Marathon Training Pace Mistakes

• Running easy days too hard
• Using goal pace instead of current fitness
• Racing workouts instead of training through them
• Forcing pace in heat, hills, or fatigue
• Running the same pace every day
• Trying to use every pace category every week

Final Thoughts

If there is one idea I want you to remember, it is this:

Give every run a purpose. Then have the discipline to run it at the intensity that accomplishes that purpose.

Going faster on an easy day does not make it a better easy day. In the same way, running too slowly in a workout may prevent you from getting the intended benefit. The goal is not to run fast every day. The goal is to train intelligently enough that each run supports the rest of your training.

That is how marathoners get faster.
