How To Taper Correctly To Be Ready For Your Marathon – Maximize Your Performance

The moment has arrived! You’ve spent countless hours training, pounding the pavement, and preparing yourself both mentally and physically for the marathon ahead. But, as the big day draws closer, it’s crucial to ensure you’re in optimal condition to perform your best. This is where the tapering phase comes into play. 

Often overlooked, this is a crucial element of marathon preparation that can make or break your race day experience. In this comprehensive guide, we’ll dive into the importance of tapering, the science behind it, and how to taper correctly to ensure you’re fully prepared for your marathon. So, grab your water bottle, lace up your shoes, and let’s get started!

The Importance of Tapering

Tapering is the process of reducing your training volume and intensity in the weeks leading up to a marathon. It’s a crucial aspect of the overall marathon training plan, as it allows your body to recover from the accumulated fatigue of months of training. Doing this properly can lead to the following benefits:

1. Enhanced performance

Research has shown that a well-executed taper can improve marathon performance by 2-3% [source]. While this might not seem like a significant figure, it can translate to several minutes off your finishing time.

2. Injury prevention

Tapering allows your body to heal and repair any minor injuries sustained during training. Continuing to push through high-intensity training without allowing time for recovery increases the risk of injury and can derail your marathon plans.

3. Mental preparation

Tapering provides an opportunity to mentally prepare for the race ahead. The reduced training load allows you to focus on race strategy, visualization, and building your confidence.

4. Boosted immune system

Intense training can put a strain on your immune system, making you more susceptible to illness. Tapering helps to restore your immune function, ensuring you’re in peak health for race day.

The Science Behind It

The Science Behind Tapering

To understand how tapering works, it’s essential to recognize the physiological adaptations that occur during this process:

Glycogen stores

During the taper, your muscles have time to replenish their glycogen stores, providing you with the necessary energy to power through the marathon.

Muscle repair

Intense training can lead to microscopic muscle damage. Tapering allows these muscles to repair and rebuild, ultimately making them stronger and more resilient.

Hormonal balance

Overtraining can cause hormonal imbalances, such as increased cortisol levels. Tapering helps to restore hormonal balance, ensuring your body is functioning optimally on race day.

VO2 max and lactate threshold

Studies have shown that tapering can lead to improvements in VO2 max and lactate threshold, both of which are critical factors in marathon performance.

How to Taper Correctly

Now that we understand the importance of this process and the science behind it, let’s dive into how to execute a successful taper:


The ideal taper duration varies depending on your level of experience and the intensity of your training plan. Generally, a 2-3 week taper is recommended for most marathoners.

Training volume

Your overall training volume should decrease progressively during the taper. Aim for a reduction of around 20-30% in the first week, followed by a 40-60% reduction in the second week. During the final week, reduce your training volume by 60-80%.


While it’s crucial to reduce your training volume, it’s equally important to maintain some level of intensity. Include some marathon pace workouts and short interval sessions to keep your legs feeling sharp and your cardiovascular system primed. However, avoid overexerting yourself or introducing new workouts during this time.

Rest days

Incorporate more rest days to allow for adequate recovery. A good rule of thumb is to include at least two rest days per week, especially in the final week leading up to the race.



Maintain your fitness level by incorporating low-impact cross-training activities, such as swimming or cycling. This will help keep you active without putting undue stress on your joints and muscles.


During the taper, it’s essential to maintain a balanced diet rich in carbohydrates, protein, and healthy fats. This will ensure that your body has the necessary fuel to rebuild and recover. Additionally, consider increasing your carbohydrate intake in the final few days before the race to maximize your glycogen stores.


Staying well-hydrated is crucial during the tapering process. Aim to drink at least 8-10 glasses of water per day, and consider incorporating electrolyte drinks to maintain a proper balance of fluids and electrolytes.


Prioritize sleep during the tapering period, as it plays a vital role in recovery and overall well-being. Aim for at least 7-9 hours of sleep per night to ensure your body is well-rested and ready for race day.

Mental preparation

Use the additional free time during your taper to focus on mental preparation. Visualize yourself crossing the finish line, practice positive self-talk, and develop a race day strategy.

Trust the process

It’s normal to feel anxious or doubt your fitness during this process, but trust in your training and remember that reducing your workload is essential for optimal performance. Embrace the taper and enjoy the opportunity to rest and recharge before your big day.

Mistakes You Need to Avoid

Tapering Mistakes

To ensure a successful taper, be mindful of these common mistakes:

1. Over-tapering

While it’s essential to reduce your training volume, completely cutting out workouts or dramatically reducing your intensity can leave you feeling sluggish and unprepared on race day.

2. Under-tapering

On the flip side, not reducing your training volume enough can lead to accumulated fatigue and poor performance.

3. Changing your routine

The tapering period is not the time to try new workouts, introduce new gear, or make significant changes to your nutrition. Stick to what has worked for you during your training.

4. Overeating

With reduced training, it’s easy to consume more calories than you’re burning. Monitor your calorie intake to avoid unwanted weight gain before the race.

5. Neglecting mental preparation

Don’t underestimate the importance of mental preparation during the tapering period. Use this time to build your confidence and develop a solid race day strategy.

Final Words

Tapering is a vital component of your marathon training plan. Understanding its importance, the science behind it, and how to execute it properly will allow you to set yourself up for success on race day. So, trust the process, prioritize recovery, and approach the starting line feeling strong, confident, and ready to conquer those 26.2 miles.
