The short answer: in the final race week, reduce training volume while retaining brief, familiar efforts and enough frequency that swim, bike and run still feel normal. The exact reduction and taper length depend on race distance, prior load, experience and your response.
A taper is not complete rest and it is not a final fitness block. It is a planned reduction in load that gives the work already completed a better chance to appear on race day.
Race week is for arriving with your fitness intact.
Why You Feel Terrible
This is the part nobody warns people about, and it causes most of the damage.
When training load drops sharply, your body does not immediately feel fresh. For the first few days it often feels worse. Heavy legs, poor sleep, a sluggish easy run, a swim where nothing works. Athletes read this as evidence that the taper is going wrong.
Heavy or unfamiliar legs do not automatically mean the taper has failed. Do not diagnose readiness from one session. Look at the trend across sleep, mood, soreness and easy movement, and avoid adding an unplanned hard test for reassurance.
What Actually Comes Down
Volume comes down. A 2023 meta-analysis found performance benefits across several taper durations and reported effective strategies that progressively reduced volume by roughly 41 to 60 percent while maintaining intensity and frequency. That is a research range, not a compulsory individual prescription.
Intensity can often be retained in much smaller doses while volume falls. For some athletes, that means a few hundreds at race pace in the pool, short familiar efforts on the bike or a handful of strides. Keep the work controlled and already rehearsed.
Those efforts are not there to build new fitness. They can preserve familiarity with race pace without adding much load, but they are optional when illness, injury, travel or poor recovery makes rest the better choice.
Frequency is often maintained, but not at any cost. A travel day, poor sleep, illness or injury can justify a different choice. The goal is familiarity without accumulating new fatigue.
Evidence: 2023 systematic review and meta-analysis of tapering in endurance athletes. The included studies span endurance sports, so use the range as context rather than a personalised triathlon prescription.
The Things People Do That Cost Them
A last long session to prove fitness can add fatigue without creating meaningful new adaptation before race day. The work is already done, so avoid using a late four hour ride as a confidence test.
A new bike fit, new shoes, new saddle, new nutrition. Race week is the single worst time to change anything, and the urge to optimise gets strongest exactly when it should be resisted.
A sudden nutrition overhaul. Use the foods, fluids and timing already rehearsed, and follow qualified guidance appropriate to your event and health needs.
A complete change in sleep routine can also create more pressure. Protect several nights of normal sleep rather than treating one perfect night as essential.
What I Actually Ask For
Keep your normal week's shape and shrink it. Same days, same disciplines, much shorter, with a small amount of race pace in each.
Do the transition rehearsal once, early in the week, not the night before.
Read the race brief properly, on Monday, when you can still solve a problem. Half the race morning stress I see comes from discovering a rule or a road closure at seven in the morning.
Get your kit out on Thursday, laid out, complete. Not Friday night at eleven.
And keep the rest of your week ordinary. Athletes who take Friday off work and spend it thinking about the race arrive at the start line having already run it forty times in their head. A normal Friday is better preparation than a dedicated one.
The Nerves Are Not a Problem
Elevated heart rate, poor appetite, broken sleep, needing the toilet repeatedly. That is a nervous system preparing for something hard, and it is appropriate.
Trying to make it go away tends to make it worse. What helps is having somewhere for it to go: a long exhale, four in and six or eight out, for a few minutes at a time. Not to feel calm, but to keep the arousal at a level you can use.
The Bottom Line
Reduce volume, retain brief familiar efforts and keep the week's shape where practical. Avoid last-minute equipment, nutrition or training experiments. If you are ill, injured or experiencing concerning symptoms, the race plan is secondary to appropriate medical advice.
The work is already done. Race week is about arriving with it intact.
Keep race week responsive
Use Unbroken Protocol to place readiness beside each planned session and decide whether today's work should stay, shrink or become recovery.
