Overview

The taper is the final phase of your training before a goal race. You reduce volume while maintaining some intensity so your body can recover, repair, and supercompensate (adapt beyond its previous fitness level — your body overcompensates for the training stress). Done right, it can be worth 2–3% improvement on race day. Done wrong, you'll feel flat or overtrained.

Golden Rule: The hay is in the barn. The taper is about arriving fresh — not getting fitter.

Why Taper?

What Happens During a Taper	Benefit
Muscle fibres repair and strengthen	More power on race day
Glycogen (your muscles' stored carbohydrate energy) stores fully replenish	More fuel available
Immune system recovers	Less chance of pre-race illness
Mental fatigue lifts	You feel sharp and motivated
Inflammation reduces	Less soreness, better range of motion

How Long Should You Taper?

Race Distance	Taper Length	Volume Reduction
5K	5–7 days	20–30%
10K	7–10 days	30–40%
Half Marathon	10–14 days	40–50%
Marathon	2–3 weeks	40–60%
Ultra Marathon	2–3 weeks	50–70%

The Three Rules of Tapering

1. Reduce Volume, Not Intensity

Do	Don't
Cut the number of reps or distance of runs	Cut out quality sessions entirely
Reduce long run distance significantly	Drop all running and do nothing
Keep some tempo or race-pace work	Add new sessions or try new workouts

2. Reduce Gradually

Week	Volume vs Peak Training	Example (60 km/week peak)
3 weeks out	75–80%	45–48 km
2 weeks out	60–65%	36–39 km
Race week	30–40%	18–24 km

3. Trust the Process

The taper feels wrong. You'll feel restless, sluggish, and convinced you're losing fitness. You're not. This is normal.

The Taper Crazies

Almost every runner experiences psychological weirdness during the taper. It's so common it has a name: the taper crazies.

Symptom	Why It Happens	What to Do
Feeling sluggish	Your body is repairing — this takes energy	Trust it. You'll feel sharp on race day
Phantom injuries	Less running = more body awareness. You notice things you normally ignore	If it's new, rest. If it's always been there, it's fine
Restless energy	You're used to training hard — the sudden drop feels strange	Go for walks, do light cross-training
Doubt and anxiety	"Am I fit enough? Did I train enough?"	You did the work. The taper proves it
Irritability	Running is your stress release — less running = more stress	Channel energy into race prep, visualisation

Race Week Checklist

Day	Action
Monday	Rest. Confirm travel plans and logistics
Tuesday	Short quality session. Check race day kit
Wednesday	Easy run. Pack your race bag
Thursday	Rest or very easy 3 km. Eat well — begin carb focus
Friday	Shakeout jog + strides (if racing Sunday). Pin race number to top
Saturday	Rest. Lay out kit. Eat your pre-race meal. Early night
Race morning	Tested breakfast 2–3 hours before. Arrive early. Trust your training

Nutrition During the Taper

Focus	Details
Maintain calories	Don't cut food because you're running less — your body needs fuel to repair
Increase carbs (final 2–3 days)	8–10g per kg bodyweight to top up glycogen (stored energy)
Stay hydrated	Aim for pale yellow urine
Avoid new foods	Stick to what your stomach knows
Limit alcohol	It impairs recovery and disrupts sleep

Common Taper Mistakes

Mistake	Problem	Fix
Not tapering at all	Arrive at the start line fatigued	Trust the research — tapering works
Doing a last big session	One session can't improve fitness — it just adds fatigue	Your last hard session should be 10–14 days before race day
Cutting all intensity	You lose sharpness and feel flat	Keep some short, fast work in the taper
Eating less because running less	Under-fuelled on race day	Maintain or slightly increase food intake
Stressing about the taper	Stress is stress — it affects recovery	Relax. Read. Sleep. Visualise race day
