Why aim for a 4-hour marathon?
A 4-hour marathon is a fantastic goal for many runners. The median marathon finish time is 4 hours 17 minutes, so running a 4-hour marathon will place you in the top half of the field at most races.
This race demands endurance, but also a balanced approach that respects your pace and lifestyle. If you are looking for a rewarding marathon experience without excessive pressure, this is the perfect plan for you.
Requirements for running a 4-hour marathon
First, make sure you have a solid running base. If you can comfortably run 30 to 40 kilometres per week, you are ready to begin this plan. Remember, the key is to progress at your own pace.
Running a marathon in 4:00 means holding an average pace of 5:41 per kilometre, or 10.5 km/h. Ideally, you should be able to run 10K in 50 minutes and have already completed a marathon in under 4:30.

12-week 4-hour marathon training plan
A 12-week training plan will help you progressively build distance and endurance. It includes long runs at a moderate pace, marathon pace sessions, easy runs for recovery and essential rest days. The focus is on building strong endurance without overtraining.
You can also begin your marathon build-up later, for example with an 8-week plan if you run year-round.
To run a marathon in under 4 hours, the minimum is two to three runs per week. We recommend running three to four times per week during your preparation. If you are not used to running, you can replace one weekly session with cycling or swimming.
In addition, strength and conditioning, including core work and leg strengthening exercises, is highly recommended.
Here is an extract from your 12-week 4-hour marathon training plan (shown below):
| DAY 1 | DAY 2 | DAY 3 | |
| Week 1 Specific preparation | 1-hour easy run | 25 min easy run + 5 x 3 min at 10K race pace (1 min 30 recovery) + 5 min easy run | 50 min easy run + 4 strides |
| Week 7 Recovery week | 1h30 easy run | 25 min easy run + 8 x 1 min at vVO2max pace (1 min recovery) | 50 min steady endurance |
| Week 10 Specific preparation | 2h15 easy run | 10 min easy run + 2 x 30 min at marathon race pace (5 min recovery) | 1h15 easy run |
Sub-4 marathon preparation: 8 weeks and 4 sessions per week
Fueling for a 4-hour marathon
For a 4-hour marathon, your nutrition should support your training without becoming overly complicated. Focus on balanced meals and regular hydration. The goal is to maintain your energy and health throughout the programme.
During the race, eating around ten gels can be difficult and may lead to stomach issues. You can choose a mixed fueling strategy, alternating gels and fruit purées. Test your race-day strategy in training. For example, during the marathon you could have a fruit purée after 50 minutes, then a gel 25 minutes later, another fruit purée 25 minutes after that, and so on until the finish.
Remember to hydrate at every aid stationif they are spaced every 5 kilometres, and even more regularly if the aid stations are farther apart. You do not need to finish the whole bottle or cup, take between 5 and 8 sips depending on the heat.
Equipment for a 4-hour marathon
Having comfortable, suitable gear is crucial. Choose well-fitting running shoes and breathable clothing.
You can also use accessories such as hydration belts to carry your gels and fruit purées. Hydration packs are not essential, as aid stations are available roughly every 25 minutes, but use one if you need it to carry a phone as well, for example. If so, run with it occasionally during training so you can get used to it.
Carbon-plated shoes are not necessarily needed, as they provide limited energy return at 10.5 km/h and require suitable running biomechanics, particularly strong core stability to avoid lower back pain late in the race.
Race strategy for running a sub-4 marathon
As you prepare for a 4-hour marathon, stay positive and motivated throughout your training. Set weekly goals and celebrate every small win. The key is to enjoy the process and remember why you started this adventure.
On race day, aim to stay consistent, reaching halfway in 2 hours, or even a little faster in 1:55, as the final kilometres are often challenging for marathon runners when the infamous marathon wall hits.
If you feel the need, you can walk through aid stations to drink or fuel.
If you want to go further and build your race strategy, we have developed a tool that lets you create a personalised race plan: split times, paces, fueling and hydration management, everything you need to manage your race on the big day.

Mistakes to avoid in a 4-hour marathon training plan
Be careful not to neglect rest and recovery. Avoid increasing your mileage too quickly and make sure you respect your rest days. Listen to your body and watch for signs of fatigue, pain and even cramps.
Make sure to test your gear and fueling strategy during your marathon preparation.
Another common mistake is running a little too fast too often. Respect easy run paces to recover properly and build your aerobic fitness.

FAQ: 4-hour marathon training plan
What pace do you need to run a 4-hour marathon?
To finish a marathon in 4 hours, you need to maintain an average pace of around 5:41 per kilometre. The marathon pace sessions in the plan help you become familiar with this rhythm and build the endurance needed to hold it all the way to the finish line.
What half-marathon time do you need?
A half marathon run in around 1:50 to 1:55 is generally a good foundation for targeting a 4-hour marathon. Specific marathon training remains essential, however, to sustain the effort over the full distance.
How can you run your first marathon in under 4 hours?
To run your first marathon in under 4 hours, it is essential to follow your training plan, start at a controlled pace and test your fueling strategy before race day.
What race strategy should you use?
The best strategy is often to run steadily from the start without getting carried away by the race atmosphere. Managing the opening kilometres conservatively helps prevent a major slowdown late in the race.
How many long runs do you need?
Most marathon training plans include between 8 and 12 long runs. These sessions build endurance, improve your use of energy stores and prepare your body for prolonged effort.
