Phase 1: Building the Foundation (Weeks 1-5)


In the initial phase, the goal is to ease your body into the training volume and physical demands of running while developing a consistent running routine. During these weeks, you'll start with a modest weekly volume of around 20 kilometers. Your runs should be easy to moderate, allowing your body to adapt gradually.


I remember my first few weeks of training; it was tough to establish a routine. Setting realistic goals and celebrating small milestones kept me motivated. One of the biggest challenges was finding the right pair of running shoes. I spent hours researching and trying different brands until I found the perfect fit. Don’t hesitate to invest time and money in quality gear—it makes a significant difference.


Example Schedule:


  • Monday: 3 km easy run

  • Tuesday: 3 km easy run

  • Wednesday: Rest or cross-training

  • Thursday: 3 km easy run

  • Friday: 3 km easy run

  • Saturday: 5 km easy run

  • Sunday: Rest


Consistency is key in this phase. Keep showing up no matter how you feel, as building a habit is crucial. Invest in high-quality shoes and gear to prevent injuries and discomfort. Alternating running surfaces can also help reduce the risk of injury.


Phase 2: Increasing Intensity (Weeks 6-10)


This phase focuses on incorporating high-intensity sessions to build aerobic capacity and speed while gradually increasing your weekly training volume. Aim to increase your weekly mileage to approximately 30-35 kilometers. Introduce one high-intensity interval training (HIIT) session per week to boost your performance.


Example Schedule:

  • Monday: 5 km easy run

  • Tuesday: 5 km moderate run

  • Wednesday: Rest or cross-training

  • Thursday: 5 km easy run

  • Friday: 7 km moderate run

  • Saturday: 7 km easy run

  • Sunday: Rest


Experiment with different training methods to find what works best for you. Proper nutrition before, during, and after your runs is essential. Fuel your body with the right nutrients to enhance performance and recovery. For detailed nutrition plans and training tips, download the Ripletic app and explore the resources available.





Phase 3: Peak Training (Weeks 11-16)


This is the most intense phase, designed to maximize your endurance and stamina. Your weekly mileage should peak at around 45-50 kilometers. Your routine will now include one interval training session and one long run per week.


Example Schedule:


  • Monday: 7 km easy run

  • Tuesday: 10 km moderate run

  • Wednesday: 6 x 800m intervals with 400m jog in between

  • Thursday: 7 km easy run

  • Friday: 15 km easy run

  • Saturday: Rest or cross-training

  • Sunday: Long run (20-25 km)


Training with others can keep you motivated and accountable. Pay close attention to hydration, optimal nutrition, and proper recovery practices during this high-demand phase. I found that joining a running group provided a much-needed boost in motivation and camaraderie. Sharing the journey with others who had similar goals made a significant difference.

Phase 4: Tapering (Weeks 17-20)


In the final phase, reduce your training volume to allow your body to recover and be race-ready. This tapering phase helps maintain fitness while minimizing fatigue. Gradually decrease your weekly mileage to about 20 kilometers, focusing on short, easy runs with a few race-pace runs.


Example Schedule:


  • Monday: 7 km easy run

  • Tuesday: 5 km easy run

  • Wednesday: 3 x 2 km intervals with 400m jog in between

  • Thursday: 5 km easy run

  • Friday: 3 km easy run

  • Saturday: Rest

  • Sunday: Marathon race day


Stick to your routine to avoid any surprises on race day. Prioritize sleep, hydration, and stretching to ensure you’re in peak condition. I remember feeling anxious during my tapering phase, worried that reducing my mileage would affect my performance. However, trusting the process and focusing on recovery made a substantial difference on race day.

Nutrition: 20-Week Marathon Training Plan for Beginners.


Proper nutrition is crucial for optimal performance during marathon training. Before your runs, focus on easily digestible carbohydrates like fruit, oatmeal, and toast with condiments. Consuming 3 mg of caffeine per kilogram of body weight can also enhance endurance. During your runs, maintain energy levels with energy gels, sports drinks, and easily digestible snacks, aiming for 0.5 to 0.6g/kg of rapidly absorbed carbohydrates every 30 minutes. After your runs, replenish glycogen stores with sports drinks, protein shakes, and balanced meals that include complex carbohydrates, lean proteins, and healthy fats.


In general, the ideal macronutrient breakdown for marathon training is 50-60% carbohydrates, 15-20% protein, and 20-30% fat. The American College of Sports Medicine recommends consuming 6-10g/kg of carbohydrates per day to support your training demands. Planning and preparing meals in advance helped me stay on track with my nutrition goals. I found that having a variety of snacks and meals ready ensured I was fueling my body correctly without having to make last-minute decisions.


Recovery Practices: 20-Week Marathon Training Plan for Beginners.


Recovery is essential for muscle repair and overall performance improvement. Aim for 7-9 hours of sleep per night to facilitate muscle repair. Cold therapy, such as cold water immersion, can reduce muscle soreness and inflammation. Incorporate dynamic stretching before runs to increase blood flow and static stretching after runs to improve flexibility. Consider supplements like omega-3 to reduce inflammation and sports drinks to maintain hydration and electrolyte balance.


Additionally, foam rolling and massage therapy can be beneficial for relieving muscle tension and promoting recovery. Integrating yoga into your routine can also improve flexibility and mental clarity, helping you stay balanced and focused throughout your training.

Race Day Tips


Preparation is crucial for race day. Arrive early to avoid stress and ensure you have ample time to warm up. Familiarise yourself with the course to plan your pacing and prepare for challenging sections. During the race, start slow to conserve energy and avoid early burnout. Stick to your race plan and break the race into manageable sections. Focus on proper hydration and nutrition throughout the race. After the race, celebrate your achievement with friends and family, as completing a marathon is a significant accomplishment.


A detailed checklist can be incredibly helpful for race day preparation. Make sure you have all your gear, nutrition, and hydration needs sorted out the night before. Knowing that you are well-prepared can alleviate stress and allow you to focus on the race.
