How to Taper for Your First Marathon

By Haleigh Hockenberry · Thu, Jul 2, 2026, 2:57 PM

The marathon taper is the final phase of training before race day and is designed to help your body recover, rebuild, and reach peak performance. After months of high mileage and demanding long runs, the taper allows accumulated fatigue to fade while preserving the fitness you've worked so hard to build.

Many runners fear they'll lose fitness by running less, but research consistently shows that reducing training volume while maintaining some intensity improves performance and reduces race-day fatigue. A successful marathon taper combines reduced mileage, strategic workouts, proper recovery, and a well-planned nutrition strategy.

How Long Should a Marathon Taper Be?

Most marathon training plans use a taper of two to three weeks. The exact length depends on your experience level, training volume, and recovery needs.

Runners averaging 30–45 miles per week often do well with a two-week taper, while those running 50–70+ miles per week generally benefit from a three-week taper.

The goal is simple: reduce overall mileage while maintaining enough running frequency to keep your legs feeling sharp.

What Should Mileage Look Like During Taper Weeks?

A common approach is to gradually reduce weekly mileage while keeping a few quality workouts in your schedule.

Three Weeks Before Race Day

Reduce mileage to approximately 80–85% of peak volume.

For example:

• Peak training week: 60 miles
• Taper Week 1: 48–52 miles

This is often when you'll complete your final significant long run, usually 16–20 miles depending on your training plan.

Two Weeks Before Race Day

Reduce mileage to approximately 60–70% of peak volume.

For example:

• Peak training week: 60 miles
• Taper Week 2: 36–42 miles

Long runs are typically shortened to 10–14 miles. Most runners still include a workout featuring marathon pace segments or short tempo efforts.

Race Week

Reduce mileage to approximately 30–50% of peak volume.

For example:

• Peak training week: 60 miles
• Race Week: 18–30 miles plus the marathon

Runs should be short, easy, and focused on staying loose. Most runners complete one light workout early in the week that includes a few marathon pace miles or short strides.

How Many Workouts Should You Do?

One of the biggest taper mistakes is eliminating all intensity. While volume decreases significantly, maintaining some race-specific effort helps preserve fitness and confidence.

A typical taper schedule may include:

• One marathon pace workout each week
• One shorter speed or tempo session during the early taper
• Easy recovery runs
• One long run that gradually decreases in length

Avoid hard interval sessions, excessive hill workouts, or attempts to test fitness. The purpose of the taper is recovery, not gaining additional fitness.

Nutrition Becomes Even More Important During the Taper

As mileage decreases, your body begins repairing muscle tissue and restoring depleted glycogen stores. This makes nutrition one of the most important aspects of a successful taper.

Focus on:

• Consistent carbohydrate intake
• Lean protein at every meal
• Healthy fats
• Daily hydration
• Adequate electrolyte intake

Many runners mistakenly reduce calories too aggressively when mileage drops. While you may not need as much food as during peak training, this is not the time to diet or restrict carbohydrates.

Carbohydrate Loading Before Race Day

During the final 48–72 hours before the marathon, gradually increase carbohydrate intake to maximize glycogen storage.

Good carbohydrate sources include:

• Rice
• Pasta
• Potatoes
• Oatmeal
• Bread
• Fruit
• Sports drinks

Avoid overeating or "stuffing yourself" the night before the race. Effective carbohydrate loading occurs over several days, not a single meal.

Prioritize Recovery During the Taper

The taper is when training adaptations occur. Prioritize:

• 7–9 hours of sleep per night
• Hydration throughout the day
• Mobility and light stretching
• Stress management
• Consistent meal timing

Many runners experience "taper madness," where reduced mileage creates anxiety about fitness. Trust your training. The hard work is already done.

Peak on Race Day

A successful marathon taper isn't about doing more, it's about doing less strategically. By reducing mileage, maintaining a small amount of intensity, prioritizing recovery, and following a smart nutrition plan, you'll arrive at the starting line rested, fueled, and ready to perform at your highest level.
