How to Taper For Your Next Race

A taper is the period of reduced training that takes place before an important race. During this time, runners gradually decrease their overall mileage and training stress so the body can fully recover while still maintaining fitness. The goal of a taper is simple: arrive at the start line feeling fresh, energised and ready to perform.

When you train, every run places stress on your body. Long runs challenge your aerobic system, workouts stress your muscles and nervous system, and high weekly mileage accumulates fatigue over time. This stress is not what actually makes you stronger. Instead, the improvements happen afterward, during recovery, when your body repairs and adapts to the training you have completed.

Without adequate recovery, the body cannot fully absorb the benefits of training. Fatigue builds up and performance can suffer. A taper allows runners to reduce that accumulated fatigue while holding onto the fitness they have worked so hard to build.

This balance between recovery and maintaining fitness is the central purpose of a taper. Done correctly, it allows the body to repair muscle damage, restore energy stores and stabilise hormone levels, all while keeping the neuromuscular system sharp for race day.

Many runners feel nervous about reducing their mileage before an important race. After weeks or months of consistent training, it can feel counterintuitive to suddenly run less. However, research and decades of coaching experience consistently show that tapering improves performance.

During heavy training periods, runners accumulate what is often referred to as 'training fatigue'. This fatigue affects muscle function, energy levels and overall performance. When training volume is reduced, the body begins to shed this fatigue while retaining most of the physiological adaptations created during training.

As a result, many runners notice that their legs begin to feel lighter and more responsive in the days leading up to a race. This is often referred to as “fresh legs”, and it is one of the primary goals of tapering.

The ideal taper length depends on the race distance and the amount of training you have been doing. Longer races typically require longer tapers because they involve higher training volumes and more accumulated fatigue.

A general guideline looks like this:

These timelines are not rigid rules. Experienced runners with high training loads may benefit from slightly longer tapers, while beginners may only need modest reductions in training. The key principle is gradual reduction rather than sudden rest.

The first phase of the taper typically begins after your final major training session. For most runners this is the last long run or hardest workout of the training cycle.

At this stage, the goal is to begin reducing fatigue while maintaining the rhythm of your normal training routine. Rather than dramatically cutting the number of runs you do each week, it is usually more effective to shorten the duration of those runs.

A common guideline is to reduce your weekly mileage to roughly 60–70 percent of your highest training week. Maintaining the same number of running days helps preserve routine and keeps the body moving, while shorter runs reduce cumulative fatigue.

Workouts can still occur during this phase, but they should be shorter and slightly less demanding than normal. The aim is simply to remind the body how race pace feels without creating new fatigue.

For example, a runner preparing for a half marathon might perform a short tempo session or a few race pace intervals during this period, but the total amount of hard running should be noticeably reduced compared to earlier weeks of training.

The final week and days of the taper focuses on freshness and recovery. By this stage, most of the heavy work has already been done. Your priority now is to arrive at the start line with fully restored energy levels and minimal fatigue.

During this week, total mileage often drops to around 40 percent of peak training volume, not including the race itself. Runs should feel relaxed and comfortable, with plenty of time for recovery between sessions.

Some runners benefit from including a few short race pace efforts early in the week. These are not full workouts, but brief reminders to keep the legs responsive. For example, a few short strides or controlled race pace intervals five or six days before the race can help maintain coordination and rhythm.

If you have not been doing speedwork in training, this is not the time to introduce it. The taper is about refining what you have already built, not experimenting with new stimuli.

The final few days before the race should consist mostly of short, easy runs or rest days, depending on what your body responds to best.

Although the principles of tapering remain the same across all race distances, the emphasis shifts slightly depending on the event.

Shorter races such as the 5 km and 10 km require less tapering because the training load leading into them is typically lower. Runners often only need to reduce mileage slightly during the final week while maintaining some intensity.

Half marathons require a slightly longer taper because long runs and weekly mileage are higher. Two weeks is generally enough time to reduce fatigue while maintaining endurance.

Marathons usually demand the longest taper. Marathon training often involves months of high mileage and extremely long runs, which can create significant cumulative fatigue. For this reason, marathon tapers often begin two to three weeks before race day.

Regardless of distance, the guiding principle remains consistent: reduce fatigue without losing the rhythm of regular running.

One of the most overlooked aspects of tapering is the psychological adjustment. Many runners experience what is commonly known as “taper anxiety.” Reduced training can leave athletes feeling restless, sluggish or even worried that they are losing fitness.

In reality, these feelings are completely normal. The body is transitioning out of a heavy training phase and into recovery mode. Temporary feelings of heaviness or sluggishness are common early in the taper, but they usually give way to increased freshness closer to race day.

Using the extra time created by reduced training can help ease this transition. Runners can focus on race logistics, sleep quality, nutrition and mental preparation. Visualising the race, planning pacing strategies and reviewing course details can all contribute to a calmer and more confident race day experience.

Consistency and restraint are the most important ingredients of a successful taper. Many runners sabotage their taper by adding extra training when they begin to feel restless.

Instead, focus on the basics. Prioritise sleep, maintain balanced nutrition and stay hydrated. Continue to run easy miles to keep the legs moving, but avoid the temptation to prove your fitness in the final days before the race.

Light mobility work, gentle stretching and short strides can help maintain coordination and prevent stiffness. However, avoid introducing new strength routines or unusually intense cross-training sessions that could create unnecessary soreness.

Above all, trust the training you have already completed.

The taper is the final stage of your training cycle. It allows your body to absorb months of consistent work and convert that training into peak performance.

By gradually reducing mileage, maintaining small touches of intensity and prioritising recovery, runners give themselves the best possible chance to arrive at the start line feeling strong and prepared.

When race morning arrives, the goal is simple. Your legs should feel fresh, your energy levels should be high and your mind should be calm. If your taper has been successful, you will stand on the start line with the quiet confidence that the hard work has already been done.
