10 Essential Tips for Marathon Training During Winter
Training for a marathon is an enormous commitment at any time of year, but preparing for 26.2 miles during the British winter brings a unique set of challenges. Dark mornings, freezing temperatures, unpredictable weather and the temptation to stay indoors can make maintaining a consistent running routine particularly difficult.
However, winter can also be an excellent time to build the strength, endurance and mental resilience needed to complete a marathon.
For anyone preparing for a spring marathon, the colder months are often when the most important groundwork takes place. Long before race day arrives, runners need to develop their fitness gradually, establish good nutritional habits and learn how to balance demanding training sessions with adequate recovery.
The key to successful marathon training in winter isn’t simply pushing through difficult conditions. It’s about following a sensible training plan, making practical adjustments for the weather and understanding how to support your body as the distances increase.
Whether you’re preparing for your first marathon or hoping to improve on a previous performance, these ten winter marathon training tips will help you approach the challenge with greater confidence.
1. Create a Realistic Marathon Training Plan
One of the biggest mistakes aspiring marathon runners make is attempting to increase their running distances too quickly.
Enthusiasm is wonderful, particularly when you’ve secured a place in a major event, but marathon preparation requires patience and consistency.
A structured training plan allows your body to adapt gradually to the demands of long-distance running while balancing harder sessions with easier workouts and rest.
Most marathon training programmes include a combination of easy runs, longer endurance sessions and workouts designed to develop speed or sustained running pace.
The exact number of weekly runs will depend on your experience, fitness and available time.
Build Your Mileage Gradually
If you’re relatively new to running, establish a comfortable running routine before beginning a demanding marathon programme.
Those who already run regularly can work towards gradually increasing their weekly mileage.
Avoid making sudden jumps in distance simply because you’ve missed a training session or feel particularly energetic.
Your cardiovascular fitness may improve more quickly than your muscles, tendons and joints adapt to the extra workload.
This is one reason gradual progression is so important.
Plan Around Your Lifestyle
A training plan should fit around your life rather than becoming an unrealistic list of obligations.
Consider work commitments, family responsibilities and the amount of daylight available during winter.
If you know that weekday evenings are particularly busy, schedule shorter sessions during the week and reserve more time for your longer weekend run.
Winter marathon training tip: Treat your training plan as a guide rather than an inflexible rulebook. Adjusting a session because of dangerous weather, illness or unusual fatigue is often the sensible choice.
2. Dress for Winter Running Without Overheating
Choosing the right clothing can make the difference between an enjoyable winter run and an uncomfortable experience.
It’s tempting to wear your warmest clothing when the temperature drops, but running generates considerable body heat.
Overdressing can leave you excessively warm and sweaty, which may become uncomfortable when you slow down or stop.
The most practical approach is to wear lightweight layers that can be adjusted according to the conditions.
Choose the Right Winter Running Layers
A typical winter running outfit might include:
- A moisture-wicking base layer: Helps move sweat away from your skin.
- A lightweight insulating layer: Provides extra warmth when temperatures are particularly low.
- A breathable running jacket: Offers protection against wind and rain.
- Running tights or leggings: Provide additional coverage during colder sessions.
- Gloves and a lightweight hat: Help protect exposed areas when necessary.
Avoid relying on heavy cotton clothing, which can retain moisture and leave you feeling cold.
Consider Wind and Rain
The temperature displayed on your weather app doesn’t always reflect how cold you’ll feel outdoors.
Strong winds, heavy rain and damp clothing can make winter running considerably more uncomfortable.
Choose clothing that offers appropriate protection while remaining breathable.
Winter marathon training tip: Start your run feeling slightly cool rather than excessively warm, but make sure you’re adequately protected against genuinely cold conditions. Carry an additional layer for longer runs, particularly if you might need to stop.
3. Make Your Winter Running Routes Safer
Shorter days create additional challenges for marathon runners, particularly those fitting training around work.
During the winter months, it’s easy to find yourself running before sunrise or after sunset.
Although running in the dark can be perfectly manageable, it’s important to take sensible precautions.
Improve Your Visibility
Choose running clothing featuring reflective details, particularly when using roads or shared routes.
A lightweight running light or head torch can improve visibility, although it shouldn’t be treated as a substitute for reflective clothing.
When possible, select well-lit routes with pavements and clearly marked crossings.
Watch Out for Ice and Slippery Surfaces
Icy pavements, wet leaves and untreated paths can significantly increase the risk of slipping.
Be particularly cautious on bridges, shaded stretches of road and routes where water tends to collect.
If conditions are hazardous, consider moving your training session indoors.
A treadmill run is far preferable to sustaining an injury because you felt obliged to complete a particular outdoor route.
Let Someone Know Your Plans
For longer runs, tell someone where you’re going and roughly when you expect to return.
Carry a charged mobile phone and consider sharing your location with a trusted person.
Winter marathon training tip: Plan several alternative routes so you can adapt to changing weather, daylight and surface conditions without abandoning your training unnecessarily.
4. Prioritise Your Weekly Long Run
Long runs are a fundamental part of marathon preparation.
They help develop endurance, allow you to become accustomed to spending extended periods on your feet and provide an opportunity to practise the practical aspects of race-day preparation.
However, a long run shouldn’t automatically become a test of how quickly you can cover the distance.
For many runners, these sessions are most productive when completed at a comfortable, conversational pace.
Focus on Time and Distance
Your training plan should gradually prepare you for longer distances, with appropriate recovery built into the schedule.
A beginner’s long run will look very different from that of an experienced runner preparing for a personal best.
Rather than comparing your distances with other runners, concentrate on following a programme suited to your current abilities.
Practise Your Race-Day Routine
Long runs provide an excellent opportunity to experiment with:
- Pre-run breakfasts
- Hydration strategies
- Energy gels and other carbohydrate sources
- Running shoes and socks
- Clothing combinations
- Pacing strategies
Discovering that a particular energy gel upsets your stomach is considerably less inconvenient during a training run than halfway through a marathon.
Winter marathon training tip: Don’t attempt to make up for a missed long run by dramatically increasing the distance the following week. Resume your training sensibly and adjust the plan where necessary.
5. Fuel Your Body with the Right Nutrition
Nutrition becomes increasingly important as marathon training progresses.
Long-distance running requires considerable energy, and consistently eating too little can affect your performance, recovery and general wellbeing.
While there’s no single diet that works perfectly for every marathon runner, a balanced approach involving carbohydrates, protein, healthy fats and a variety of nutrient-rich foods provides a strong foundation.
Don’t Underestimate Carbohydrates
Carbohydrates are particularly valuable for endurance exercise because they help replenish the body’s glycogen stores.
As training distances increase, your carbohydrate requirements may rise.
Useful foods include:
- Porridge and other oat-based breakfasts
- Rice and pasta
- Potatoes and sweet potatoes
- Wholegrain bread
- Fruit
- Breakfast cereals
- Couscous and other grains
The amounts you need will depend on your body size, training intensity and overall activity level.
Include Protein for Recovery
Protein supports the maintenance and repair of muscle tissue.
Rather than concentrating all your protein intake into one large meal, consider including a source with your regular meals throughout the day.
Chicken, fish, eggs, yoghurt, tofu, beans and lentils can all contribute to your requirements.
Eat a Variety of Fruit and Vegetables
Winter training doesn’t require a complicated collection of supplements.
A varied diet containing vegetables, fruit, wholegrains and protein-rich foods can provide many of the nutrients your body needs.
Iron, calcium and vitamin D are also important considerations, although supplements should be selected according to individual needs and appropriate guidance rather than taken indiscriminately.
Eat After Longer Training Sessions
After a demanding run, a meal or snack containing carbohydrates and protein can help replenish energy stores and support recovery.
Something as straightforward as eggs on toast, Greek yoghurt with fruit and oats, or chicken with rice can work well.
Winter marathon training tip: Don’t deliberately restrict food intake to lose weight while increasing your mileage. Under-fuelling can undermine training and health, so seek advice from a qualified sports dietitian if you’re struggling to meet your energy needs.
6. Remember to Hydrate Even When It’s Cold
Many people naturally drink less during winter because they don’t feel as thirsty as they do in hot weather.
However, cooler temperatures don’t eliminate the need for hydration.
You still lose fluid through sweating and breathing during exercise, particularly when running for extended periods.
Develop a Sensible Drinking Routine
Drink regularly throughout the day and begin longer runs adequately hydrated.
For extended sessions, consider carrying water or planning routes that provide access to drinks.
Some runners may also benefit from sports drinks containing carbohydrates and electrolytes, depending on the duration and intensity of the session.
Avoid Drinking Excessively
More water isn’t always better.
Drinking excessive amounts during prolonged exercise can dilute sodium levels in the blood, potentially causing a dangerous condition known as exercise-associated hyponatraemia.
Rather than forcing yourself to drink large quantities, develop an individual hydration strategy informed by your thirst, sweat losses, training duration and conditions.
Winter marathon training tip: Practise your hydration approach during long runs so you understand what works comfortably for you before race day.
7. Include Strength Training to Support Your Running
Marathon preparation isn’t exclusively about running.
Strength training can help runners develop the muscular capacity needed to tolerate repeated loading and may improve running performance.
It can also address weaknesses that become more noticeable as weekly mileage increases.
You don’t necessarily need an elaborate gym programme to benefit.
A selection of well-performed exercises targeting your legs, hips and core can complement your running routine.
Useful Strength Exercises for Marathon Runners
Consider incorporating exercises such as:
Squats: Help strengthen the quadriceps, glutes and other muscles involved in running.
Lunges: Develop single-leg strength and control.
Calf raises: Target the calf muscles, which play an important role in running mechanics.
Glute bridges: Strengthen the muscles around the hips.
Step-ups: Provide a practical way to build lower-body strength.
Planks and other core exercises: Help develop trunk strength and control.
Avoid Doing Too Much
Strength sessions should complement your running rather than leave you too exhausted to complete important workouts.
Start with manageable resistance and increase the challenge gradually.
If you’re inexperienced with strength training, consider seeking guidance on technique.
Winter marathon training tip: Indoor strength sessions are particularly useful when poor weather makes outdoor running less appealing, but they shouldn’t automatically replace the endurance training required for a marathon.
8. Take Recovery and Sleep Seriously
Rest is an essential part of marathon preparation, not a sign that you’re failing to train hard enough.
Running creates physical stress, and the body requires sufficient time and resources to adapt.
Without adequate recovery, fatigue can accumulate, performance may decline and the risk of injury can increase.
Schedule Rest Days
Include rest days or appropriately easy sessions within your training programme.
The exact balance will depend on your experience and the demands of your schedule.
Some runners benefit from complete rest, while others enjoy gentle activity such as walking or easy cycling.
The important thing is to avoid turning every day into another demanding workout.
Protect Your Sleep
Sleep supports numerous processes involved in recovery and general health.
Consistently short or disrupted sleep can make demanding training feel considerably harder.
Try to maintain a regular sleeping routine and allow yourself sufficient time to rest, particularly after longer runs.
Recognise Signs of Excessive Fatigue
Persistent tiredness, declining performance, unusual irritability and recurring aches can indicate that your training load needs reviewing.
A single difficult run isn’t necessarily concerning, but repeated problems shouldn’t be ignored.
Winter marathon training tip: Schedule easier training periods rather than waiting until you’re completely exhausted. Progress comes from balancing training stress with sufficient recovery.
9. Look After Your Mental Motivation During Winter
Winter marathon training isn’t just a physical challenge.
Getting out of a warm bed for an early morning run or heading outdoors after a long working day requires considerable determination.
When the weather is miserable and race day still feels months away, motivation can understandably fluctuate.
Fortunately, there are several ways to make winter training more enjoyable.
Break the Challenge into Smaller Goals
Rather than constantly thinking about the full marathon distance, concentrate on manageable milestones.
These might include completing a consistent month of training, comfortably increasing your long-run distance or improving your running routine.
Small achievements provide a sense of progress throughout the programme.
Find a Running Partner or Group
Running with others can make long winter sessions feel less daunting.
A local running club may also offer structured sessions, experienced members and routes you wouldn’t otherwise discover.
For those who prefer running alone, arranging an occasional session with a friend can still provide encouragement.
Make Training Enjoyable
Not every run needs to feel like a serious athletic performance.
Explore new routes, listen to a favourite podcast where it’s safe to do so, or occasionally choose a scenic location for your weekend long run.
Allow yourself to appreciate the process rather than focusing exclusively on the finish line.
Winter marathon training tip: Motivation naturally comes and goes. A realistic, established routine can help you remain consistent without relying on feeling enthusiastic every single day.
10. Know When to Adapt Your Training
Perhaps the most valuable lesson for anyone training through winter is learning when to change the plan.
Unexpected illness, dangerous weather, work commitments and periods of fatigue can all interfere with even the most carefully organised schedule.
Missing one training session won’t automatically derail your marathon preparation.
Attempting to compensate by overtraining, however, can create unnecessary problems.
Don’t Run Through Injury
There’s an important difference between ordinary muscle fatigue and pain that may indicate an injury.
Persistent pain, swelling or symptoms that change the way you run should be taken seriously.
Avoid continuing to train through significant pain, and seek advice from an appropriate healthcare professional when necessary.
Take Illness Seriously
Winter is a particularly common time for respiratory infections.
If you’re unwell, especially with a fever, chest symptoms or significant fatigue, rest and allow yourself to recover.
Don’t attempt to catch up on missed mileage immediately after an illness.
If you’ve experienced a significant infection or ongoing symptoms, seek medical advice before resuming demanding exercise.
Have an Indoor Alternative
A treadmill, stationary bike or other suitable indoor activity can help maintain aspects of your fitness when outdoor running isn’t safe.
However, cross-training isn’t always a direct substitute for the specific endurance and physical demands of running.
Use alternative activities thoughtfully within the overall training programme.
Winter marathon training tip: Consistency matters, but so does flexibility. A sensible adjustment today may be what allows you to continue training successfully next week.
What Should a Winter Marathon Training Week Look Like?
A structured week usually combines different types of running with recovery and strength work.
The following is an illustrative routine for someone who already has an established running base. It’s not a complete beginner’s programme or a personalised marathon plan.
| Day | Training focus |
|---|---|
| Monday | Rest or gentle recovery activity |
| Tuesday | Easy run |
| Wednesday | Strength training |
| Thursday | Controlled pace or endurance workout |
| Friday | Rest |
| Saturday | Easy run or suitable cross-training |
| Sunday | Long, comfortable-paced run |
The duration and intensity of each session should reflect your experience and training programme.
Beginners may need fewer running days, while experienced marathon runners might benefit from additional sessions.
If you’re starting from little or no running experience, build your fitness through shorter distances before beginning marathon-specific training.
What Should You Eat Before a Winter Long Run?
A suitable pre-run meal can make longer training sessions considerably more comfortable.
Many runners prefer a carbohydrate-rich breakfast that is easy to digest and doesn’t contain unusually large amounts of fat or fibre.
Possible options include:
- Porridge with banana and honey
- Toast with jam
- A bagel with a familiar topping
- Breakfast cereal with milk
- Rice cakes with banana
The best choice depends on your digestive tolerance, the timing of your run and how long you expect to be exercising.
Allow sufficient time for digestion and avoid experimenting with unfamiliar foods immediately before a demanding session.
For longer runs, you’ll also need to consider whether to consume carbohydrates during exercise.
Energy gels, sports drinks, chews and certain familiar foods can all provide carbohydrate, but the appropriate amount varies according to the runner and session.
Practise during training rather than introducing a completely new fuelling strategy on race day.
Is It Better to Train for a Marathon Outside or on a Treadmill?
Both outdoor running and treadmill training have advantages.
Outdoor running allows you to practise coping with changing terrain, wind, weather and the practical challenges of running longer distances away from home.
It can also help you become familiar with the conditions you might encounter during a race.
Treadmills, meanwhile, provide a controlled environment that can be particularly useful during icy weather or when daylight is limited.
They also allow you to monitor your pace and complete structured sessions without worrying about traffic or slippery surfaces.
A combination of both can work well.
However, if your marathon takes place outdoors, it’s sensible to include sufficient outdoor running in your preparation whenever conditions permit.
When Should You Start Training for a Spring Marathon?
The ideal starting point depends on your current fitness, running history and marathon goals.
Many structured marathon plans cover approximately 16–20 weeks, although some runners benefit from a longer preparation period.
It’s important to understand that these programmes often assume a certain level of existing running fitness.
Someone who already completes regular 10km runs or half marathons will have different preparation needs from someone who has never run consistently.
For beginners, building a comfortable running base before starting a marathon plan is generally advisable.
If you’re preparing for a spring event, autumn and early winter can therefore be valuable months for gradually establishing endurance.
Making Winter Marathon Training Work for You
Preparing for a marathon during winter requires commitment, patience and a willingness to adapt.
There will inevitably be mornings when the weather is unpleasant, training sessions that feel harder than expected and weeks when progress seems frustratingly slow.
But marathon preparation isn’t about completing every session perfectly.
It’s about building endurance consistently, learning how your body responds to longer distances and developing the confidence to approach race day feeling prepared.
By combining a realistic training plan with sensible nutrition, strength work, appropriate clothing and adequate recovery, you can make the colder months a productive part of your marathon journey.
And when the warmer weather finally arrives, all those carefully planned winter miles will have helped prepare you for one of running’s greatest challenges: crossing the marathon finish line.
