Taper

Taper is the strategic reduction in training volume before a key race to maximize freshness and performance. Learn how to taper effectively without losing fitness.

Quick Answer

Taperis the strategic reduction in training volume before a key race while maintaining some intensity. A proper taper reduces fatigue without significantly decreasing fitness, allowing peak performance on race day.

What is Tapering?

Tapering is the intentional reduction of training load in the 1-3 weeks before an important event. It allows accumulated fatigue to dissipate while fitness remains high.

The key principle:

  • Fitness fades slowly (weeks)
  • Fatigue clears quickly (days)
  • Taper exploits this difference

Why Taper Works

During hard training, fatigue masks fitness:

Research shows proper tapering can improve performance by 2-6%.

Taper Duration by Race

Race TypeTaper Length
5K5-7 days
10K7-10 days
Half Marathon10-14 days
Marathon14-21 days
Half Ironman10-14 days
Ironman14-21 days

Longer events and higher training loads require longer tapers.

Taper Types

Progressive Taper

Gradual volume reduction:

  • Week 1: 80% volume
  • Week 2: 60% volume
  • Race week: 40% volume

Best for: Most athletes, longer tapers

Step Taper

Sudden volume drop:

  • Immediately drop to 50% volume
  • Maintain until race

Best for: Short tapers (5-7 days), experienced athletes

Exponential Taper

Volume drops more rapidly over time:

  • Week 1: 75%
  • Week 2: 50%
  • Race week: 25%

Best for: Very long tapers, recovery from overtraining

What to Do During Taper

Keep Doing

ActivityWhy
Short intense effortsMaintain neuromuscular sharpness
Race-pace workStay calibrated
Normal routineMental stability
Easy workoutsMaintain blood flow

Reduce or Stop

ActivityWhy
Long workoutsNot enough recovery time
New exercisesInjury risk
Maximum effortsToo fatiguing
Extra volumeDefeats purpose

Taper Feelings

Normal Taper Sensations

FeelingCause
Phantom painsHeightened body awareness
RestlessnessReduced training hormones
Legs feel flatLow adrenaline
Doubt about fitnessNot seeing hard training
Excess energyRecovery happening

These feelings are normal and don't indicate lost fitness.

Warning Signs

SignMay Indicate
Persistent fatigueTaper not long enough
Worsening moodMay need more activity
IllnessImmune system dip (common)
Weight gainAdjust nutrition slightly

Nutrition During Taper

Carbohydrate Loading

TimingCarb Intake
3-4 days beforeIncrease carbs to 8-10g/kg
Day beforeHigh carb, low fiber
Race morningFamiliar pre-race meal

Hydration

TimingFocus
Taper weekStay normally hydrated
Day beforeDon't overhydrate
Race morningSip fluids, don't chug

Common Taper Mistakes

1. Not Tapering Enough

Many athletes fear losing fitness and don't reduce volume enough. Trust the taper.

2. Tapering Too Long

Excessive taper can lead to:

  • Feeling flat on race day
  • Lost sharpness
  • Mental staleness

3. Adding Intensity

Taper isn't the time for new hard workouts. Maintain, don't increase.

4. Changing Everything

Race week isn't the time for new nutrition, gear, or routines. Stick with what works.

5. Over-analyzing Feelings

Taper feelings are unreliable. Don't mistake phantom fatigue for real problems.

Taper for Multiple Races

If Racing Frequently

SituationApproach
Weekly racesMini-taper (2-3 easy days)
Two races close togetherShort taper for first, longer for second
A-race and B-raceFull taper only for A-race

Maintaining Racing Fitness

If racing every few weeks, maintain:

  • Base volume between races
  • Short tapers before each
  • One full taper per year for A-race

Common Questions

Will I lose fitness during taper?

Minimal fitness loss occurs in 2-3 weeks of reduced training. The performance gains from reduced fatigue far outweigh any fitness loss.

What if I feel terrible during taper?

Normal! Taper feelings are notoriously unreliable. Some of the best performances come after awful-feeling tapers.

Can I do other sports during taper?

Light cross-training is fine, but avoid:

  • New activities
  • High-impact sports
  • Anything with injury risk

How do I know if my taper was too long?

Signs of over-tapering:

  • Feeling flat on race day
  • Legs feel heavy (not fresh)
  • Loss of competitive edge
  • Next time, shorten taper by 2-4 days
