Summary:
These ten running sessions offer different ways to support your marathon training as you prepare for the demands of the distance. Each workout brings a different focus, giving you options that can be adapted around the wider demands of your preparation.
Bringing Different Sessions Into Your Marathon Training
Marathon training places a considerable emphasis on running for longer, but the sessions around those longer efforts can still take many different forms. Changing what you ask from individual workouts gives you ways to develop your preparation without expecting every run to replicate the sustained demands of the marathon itself.
The ten sessions below give you a collection to draw from rather than a schedule you need to complete. Some may fit naturally into your training at one point and need adjusting at another as your overall running volume changes. The duration or number of repetitions can be reduced when needed, while recovery can be extended to make a harder session more manageable.
Explore the different intensities in our Why Do Running Zones Matter for Marathon Training? guide, which looks at how each zone can contribute to your preparation for the distance.
10 Example Marathon Run Sessions
1. Zone 2 Long Run
Purpose: Develops the endurance needed to sustain prolonged running while keeping the effort controlled enough to accumulate longer training volume.
Warm-Up: 10 min jog
Main Set: 90–150 min @ Zone 2
Cool-Down: 10 min jog
2. Zone 3 Tempo Run
Purpose: Adds a concentrated block of tempo work to marathon training, giving you prolonged exposure to a moderately hard pace without making the effort continuous.
Warm-Up: 10 min jog
Main Set: 3 x 15 min @ Zone 3 (4 min recovery between)
Cool-Down: 10 min jog
3. Zone 4 Threshold Intervals
Purpose: Introduces prolonged threshold work into marathon training, challenging you to hold a demanding pace for longer periods than you would typically encounter in shorter interval sessions.
Warm-Up: 12 min jog
Main Set: 3 x 10 min @ Zone 4 (5 min recovery between)
Cool-Down: 10 min jog
4. VO2 Intervals
Purpose: Adds a high-intensity stimulus to marathon training, challenging your ability to produce quality running well above the intensities used for most of your weekly mileage.
Warm-Up: 10 min jog
Main Set: 5 x 2 min @ Zone 5 (3 min recovery between)
Cool-Down: 10 min jog
5. Progression Long Run
Purpose: Adds a faster finish to a longer endurance run, asking you to raise the effort after an hour of steady running rather than doing the harder work while fresh.
Warm-Up: 10 min jog
Main Set: 90 min @ Zone 2, with final 30 min @ Zone 3
Cool-Down: 10 min jog
6. Marathon Pace Blocks
Purpose: Gives you extended practice at your intended marathon pace, helping you rehearse pacing and fuelling within a structured session.
Warm-Up: 10 min jog
Main Set: 3 x 5K @ estimated marathon pace (5 min recovery between)
Cool-Down: 10 min jog
7. Back-to-Back Long Runs
Purpose: Increases your running volume across consecutive days, with the second run adding tempo work while some fatigue from the previous day may still be present.
Day 1: 90 min @ Zone 2
Day 2: 60 min with final 20 min @ Zone 3
8. Threshold Cruise Intervals
Purpose: Uses short recoveries to accumulate a high volume of threshold running while keeping the demand relatively continuous across the set.
Warm-Up: 10 min jog
Main Set: 5 x 2K @ Zone 4 (90 sec easy jog between)
Cool-Down: 10 min jog
9. Tempo Into Threshold
Purpose: Creates a continuous increase in training demand, moving directly from tempo into threshold without a recovery break to reset before the harder work.
Warm-Up: 10 min jog
Main Set:
20 min @ Zone 310 min @ Zone 4
Cool-Down: 10 min jog
10. Active Recovery Run
Purpose: Provides a low-intensity run that helps maintain training frequency without adding the demands of another endurance or harder session.
Warm-Up: Optional
Main Set: 35–50 min @ Zone 1
Cool-Down: Gentle walk or mobility work
Considering the Wider Demands of Marathon Training
A marathon session does not exist on its own. As your preparation builds, the running you complete across the rest of the week can change how appropriate a particular workout is. Adding a demanding session simply because it appears useful can become counterproductive if it leaves you struggling to complete the training that follows.
This is where choosing between sessions becomes important. There may be times when a long run deserves more of your attention and a harder workout needs to be reduced or left out. At other points, your training may give you more room to explore one of the different sessions above. The aim is not to fit everything in, but to consider what makes sense within the training you are currently able to manage.

Final Thoughts
Marathon training can place considerable demands on your body as weekly running volume builds and long runs become more substantial. Those demands can take time to recover from, particularly when harder sessions are also part of your training. More intensity does not automatically make the training better if it begins to compromise your ability to recover.
These ten sessions provide different ways to approach your running, but they still sit within that much larger marathon workload. Give harder sessions the recovery they deserve and recognise when the accumulated demands of your training are already enough. Sometimes the most useful decision during marathon preparation is allowing your body the time it needs before asking for more.
