Weeks before the race

This is the time to adapt your training for the marathon and test everything from gear to fuel and hydration.

  • The longer you train for the marathon, the more likely you are to complete the distance feeling stronger. While favorable conditions may enhance your performance, always prepare for the conditions you'll encounter on race day to maximise your potential. The more prepared you are, the better equipped you'll be to handle whatever challenges arise.

  • Understanding the race course enables you to tailor your training and pacing strategy. Assess whether the course is flat or hilly, on paved or dirt roads; whether it's point-to-point, loop, or out-and-back. Consider if the course is predominantly straight or features numerous turns, and whether the roads are open or shaded. Take note of the aid station placements.

  • Preparing for the weather conditions is crucial for a successful marathon experience. Whether it's facing hot or cold temperatures, sunny or cloudy skies, humid or dry air, or windy or calm conditions, adapting your training regimen is essential. Train specifically for the anticipated weather, acclimatising your body to extreme temperatures and adjusting pacing goals accordingly.

  • When running with high effort, most of the energy exerted turns into heat, which the body must disperse to keep functioning. The warmer the climate, the harder it is for the body to cool down, causing performance to drop as core body temperature rises. Consequently, the hotter it is, the slower you will run. For every +5°C increase, you can easily add an extra 5 minutes to your marathon finish time. Slower runners are even more affected by heat than faster runners.

  • Fuel your long efforts, test what works best for you, and train your gut to handle more carbs. Practice your pre-race meals. Increase carbs and reduce fibre before the race - the last few days are critical. Hard activity for 1.5-2 hours depletes energy stores. Start taking carbs early, every 20-30 minutes, aiming for 30-60g per hour. Most gels contain 25-50g of carbs. Find the right consistency, flavor, and check if they can be taken without water. Take a gel ~15 minutes before the race (practice this!). Consume 3-6 mg of caffeine per kg of body weight, noting that caffeine metabolism varies and can take up to 45 minutes.

  • Drinking plain water is enough to replace sweat losses up to a certain point. But as you sweat more, you need to replace sodium (Na) too, to keep your body's fluid balance. How much you sweat and how much sodium you lose is very individual. On hot days, or if you’re a salty sweater, you'll need more sodium. Find out what drinks the aid stations provide and test it before race day. If it's hot, consider carrying your own electrolyte drink. Drink often and start adding sodium before the race.

  • By testing your race kit and shoes before race day, you can avoid unexpected issues and ensure a smoother marathon experience. Ensure your clothing is comfortable and appropriate for the expected weather conditions. Try different methods to carry your fuel during training runs to find the most convenient solution, or plan how to get fuel and hydration on the course. Experiment with pockets, belts, or handheld options. Make sure your race shoes are well-fitted and have been worn in to prevent blisters and other discomforts.

  • Participating in 10k or 21k test races before the marathon provides an opportunity to test your fitness level and understand what you are capable of running. Additionally, test races allow you to fine-tune your race day strategy, such as hydration and fueling, and identify any areas for improvement before tackling the full marathon distance. They can also help build confidence and set realistic goals for your marathon.

  • Calculating your expected race pace involves considering optimistic, realistic, and pessimistic race scenarios. Setting an A, B, and C goal helps maintain motivation and provides flexibility on race day. To understand your capabilities, consult with your coach or ask KULG to predict your marathon race time. Knowing your average expected race pace allows you to approach your race with confidence and adapt to varying conditions while striving to achieve your best performance.

  • During the taper period, typically advised to last around two to three weeks before the marathon, it's crucial not to leave your best performance in your training. Avoiding excessive activity during race week allows your body to rest and recover, ensuring you're well-prepared for the marathon. Overdoing it in the final days can lead to fatigue and potential injury, undermining your hard work and training efforts. Embracing the taper phase allows your body to fully absorb the training adaptations, restoring energy levels and optimising performance on race day. Trust in your training, prioritise rest, and arrive at the starting line feeling fresh and ready to give your best effort.

Race week

Prioritise rest, fueling, logistics, and final adjustments. Now is not the time to experiment anymore.

  • Increasing carb intake before the race (to 8-10g per kilogram of body weight) boosts glycogen levels in muscles, providing sustained energy for endurance performance and helping to prevent hitting the wall - a phenomenon where glycogen stores are depleted, leading to sudden fatigue and loss of performance.

  • Prioritise rest and reduce stress in the days leading up to the race to ensure optimal physical and mental readiness. Try to work less and reduce social interactions that may compromise your immunity.

  • Avoid experimenting with new foods, gear, or things you found from the marathon expo in the final days before the race to prevent potential disruptions to your routine. Stick to familiar foods that you know work well with your digestive system and trust in the training plan you've followed.

  • Aim to increase sleep duration in the days leading up to the race to optimise rest and recovery as you may not be able to sleep that much on the night before the race. Create a relaxing bedtime routine, limit screen time before bed, and ensure your sleep environment is comfortable.

  • Remind yourself of your "why," focusing on your motivations and goals to maintain perspective and boost confidence. Approach the marathon as a celebration of your hard work and dedication, rather than a test or trial, to alleviate pressure and stress. While a little race anxiety can be beneficial, try not to overthink it, and trust in your preparation and abilities to carry you through the race.

  • As race day approaches, stay updated on the weather forecast and adjust your race plan accordingly. If conditions are hot, humid, or windy, modify your pacing strategy and opt for lightweight, breathable clothing. A little rain or wind on a sunny day might even work to your advantage. Stay flexible and adapt to the weather conditions to optimise your performance on race day.

  • To ensure a smooth and stress-free race day experience, plan your logistics in reverse order, starting from your arrival time at the start line and working backward to your wake-up time. Consider factors such as transportation, bag drop, and pre-race rituals, all of which require time. By organising your schedule in this manner, you can allocate sufficient time for each task and arrive at the start line feeling prepared and relaxed.

  • Pick up your race bib early. This allows you to avoid last-minute stress and ensures you have ample time to prepare and mentally focus before the start of the race. Avoid doing long walks around the city the day before the race to conserve energy and prevent unnecessary fatigue.

  • Create a pacing strategy aligned with your training and race objectives to maintain a steady and sustainable effort during the marathon. Divide the race into manageable sections and aim for either a negative split or even splits to optimise performance and mitigate fatigue. It's essential to have a realistic understanding of your average expected race pace to execute this strategy effectively (see our marathon time calculator).

  • Set A, B, and C goals for the race to stay motivated and maintain focus during the event, even if things don’t play out perfectly. Establishing multiple goals allows you to adapt to changing circumstances and maintain a positive mindset, regardless of the outcome. Your A goal could be for example “running a marathon below 4 h”, your B goal “below 4 h and 10 min” and C goal “to finish”.

Focus on what you can control, let go of the rest.

Race day

This is it. You've prepared for this and you've planned every aspect of the race. But you cannot control everything. Listen to your body, quiet the mind.

  • Consuming a carb-rich breakfast 3-4 hours before the race ensures that you get to the start with full glycogen stores. Opt for what you have tested as your pre-race fuel before and what works for you - e.g. white bread with jam or oatmeal and a cup of coffee. Avoid fibre and fat.

  • Arriving early to the race area helps you get settled, avoid stress, and take care of any last-minute details calmly. This way, you have plenty of time to warm up, hand your things to the baggage drop, and get to the starting line without feeling rushed. Here's a sample race day agenda:

    5:30 Wake up
    5:45 Breakfast
    6:15 Get ready
    6:45 Leave building
    7:00 Transport
    7:30 Arrive to race area
    7:45 Warm-up
    8:15 Bag drop
    8:30 Find your corral
    8:45 1st gel
    9:00 Start

  • Hydrating with water containing sodium up until about an hour before the race helps maintain electrolyte balance and prevents dehydration. Sodium aids in fluid retention, ensuring your body stays hydrated longer. This practice can help you start the race well-hydrated and better prepared for the physical demands ahead.

  • A light warm-up helps get your muscles ready for the race without using too much energy. Simple stretches and a short jog are enough. Make sure your laces are tied well but not too tight to avoid tripping and blisters, making your race smoother.

  • Consuming a gel about 15 minutes before the race provides a quick energy boost from carbohydrates, helping to top off your glycogen stores. This can give you an initial energy surge to start the race strong without spiking your glucose level too early and feeling sleepy at the start. Be sure to practice this in training to ensure it agrees with your stomach.

  • Starting the race at a conservative pace helps you avoid early burnout and conserve energy for the latter stages of the marathon. Begin slower than your expected pace for the first 1-5k, then transition to your average pace from 5-21k, maintaining an effort level of 6-7/10. From 21-35k, pay attention to how hard it feels and adjust your pace if needed. Expect to slow down a bit from 35-40k, and if you have energy left, push yourself to a 10/10 effort for the final 2k. Aim for a negative split or a slightly positive split, keeping your heart rate on the lower end for as long as possible to maximise endurance.

  • Monitor your exertion level. If the race feels more challenging than you anticipated, adjust your pace immediately. Slowing down can help manage fatigue and prevent burnout, allowing you to recover and maintain a sustainable effort. You decide what's sustainable by comparing how you feel to how you expected to feel at that point in the race.

  • During the race, stay cool by pouring water over your head, using a water sponge, or running through misting stations. Drinking cold fluids and a light breeze provide natural cooling. These methods help keep your body temperature in check, especially in hot and humid weather. Wear light and breathable clothing, drink plenty of fluids with sodium before and during the race, and try to stay in the shade before starting. You can also use cooling vests, ice packs, or wet towels on your neck for extra relief.

  • Implement coping strategies like positive self-talk, visualisation, and focusing on your breathing to manage the physical and mental challenges of the race. Motivational self-talk and a race mantra ("you can do this!") can keep you motivated, while slicing up the distance into "recognisable" segments and setting mini milestones can make the race feel more manageable. Use mental distraction by thinking what you are grateful for, and focus on maintaining good form if possible.

  • Pay close attention to your body's signals to make necessary adjustments but understand that some pain and discomfort is inevitable. Your brain will urge you to slow down long before the body reaches its limits. Embrace the pain rather than fearing it. Having B and C goals can help prevent you from giving up if things get tough. Above all, remember to enjoy the experience, celebrate your progress, and take in the atmosphere. Embracing the journey can make the marathon more fulfilling and rewarding.

Marathon stages

Train smarter. Run better with KULG.

After the race

Analyse your race. You may think you’ll remember but you won’t. Write it down.

  • Compare how you executed your planned hydration and nutrition strategy during the race to see if you need to improve something.

  • Review your race splits to analyse how your pace changed throughout the marathon. Check if you ran a negative (2nd half faster) or positive split (2nd half slower).

  • Examine your heart rate data, including your average and maximum heart rate, and effort levels, to understand how your body responded to different phases of the race.

  • Evaluate your race tactics, pacing strategy, and race kit choices to determine what worked well and what might need to be adjusted for future races.

  • Reflect on your taper period to assess if you allowed adequate time for rest and recovery leading up to the race.

  • Identify the aspects of the race that went well and those that didn't, to better understand your performance and areas for growth.

  • Consider what improvements you can make for your next race, whether it's in training, strategy, or mental preparation.

  • Decide what things you should test more in your training before your next race to help you improve - e.g. in connection with nutrition, pacing, et al.

  • Avoid dwelling on negative aspects of the race for too long and focus on positive takeaways and lessons learned for future improvement. The only way to improve is through learning.

  • Keep in mind that the marathon is not just a test of performance but also an experience to embrace and learn from, enjoying the journey along the way.
