RACE PREPARATION
How should I taper before a race?
Taper by reducing training volume while keeping the routine familiar
A taper reduces accumulated training fatigue before a race, usually by lowering volume while retaining some familiar running. The amount and duration depend on the event and your training; the final days are not the time to make up missed work.
Reduce fatigue without reinventing the week
Tapering is a change in dose, not an invitation to add unfamiliar workouts. Keep the routine recognizable and reduce the amount of demanding work. The aim is to arrive ready for the event rather than to prove your fitness immediately beforehand.
A systematic review of endurance tapering found performance benefits from reduced training volume in studied athletes. Its findings describe groups and protocols, not a universal race-week prescription. A first 5K and a heavily trained marathon runner do not need identical tapers.
Understand the arithmetic
| Period | Training distance | Change |
|---|---|---|
| Comparable usual period | 40 km | Baseline |
| Taper period | 24 km | 16 km less |
| Relative reduction | 16 ÷ 40 | 40% |
This demonstrates a calculation, not a recommended reduction for everyone. Compare the same number of days, and state whether race distance is included. A marathon added to race-week totals can make a reduced training week appear unusually large.
Keep familiar intensity in proportion
A small amount of familiar faster running may remain in a plan while total volume falls. That does not mean keeping the full hard workout and simply removing all easy days. The dose and the recovery cost still matter.
Do not introduce new hill sprints, heavy strength work or a long confidence-building test. Familiarity is valuable because you have some evidence of how you respond. An experiment that creates soreness or fatigue adds uncertainty at exactly the time you are trying to reduce it.
Expect the numbers to behave differently
Training-load models respond to less recent work. Some displayed values can decline during a taper even when reducing work is intentional. Trying to keep every score rising can undermine the purpose of the week.
A single sluggish or unusually lively short run also should not determine a last-minute race target. Sleep, nerves and normal variation affect how a day feels. Focus on the established plan, practical preparation and any symptoms that actually require attention.
Review the plan on the same time basis
In Runome, compare equivalent periods and separate training from race distance. The taper arithmetic guide shows why mismatched date windows can produce the wrong conclusion.
Read why modeled fitness can fall during lower training, then use race splits to prepare checkpoints from a realistic target. If preparation was interrupted, adjust the goal; a late high-volume week cannot recreate several weeks of training and recovery.
