The taper is where many ultrarunners get restless. Training has given you something to do for months, and a reduction can feel suspicious. The appropriate change depends on the load you are carrying and how you have responded to previous reductions.
The Purpose of the Taper
A taper is intended to reduce accumulated fatigue while preserving readiness. Studies in endurance runners support a pre-competition load reduction, but most do not study 24-hour or multiday races directly. Apply those findings as context, not as a race-specific prescription.
Planning the Taper
| Planning factor | Question to ask | Possible implication |
|---|---|---|
| Preceding training load | How much volume and intensity are you recovering from? | A larger load may require a larger or earlier reduction |
| Prior taper response | What left you rested without feeling disrupted before? | Use your own history rather than copying another runner |
| Pain or illness | Are symptoms changing normal movement or daily function? | Pause the plan and seek qualified assessment |
| Race logistics | Will travel, altitude, climate, or mandatory kit add load? | Protect time for travel recovery and organization |
Decide the taper with a qualified coach when possible. A clinician or physiotherapist should guide decisions affected by injury, illness, medication, or a medical condition.
The Last Long Run
Do not force a late long run merely to prove readiness or rescue a missed training block. Any final race-specific session should already fit the plan and current health. Equipment, fueling, and lighting are better tested repeatedly earlier in training than introduced near race day.
For race-specific plans, see 24-hour, 48-hour, and 6-day training guides.
Race Week Priorities
- Protect a consistent sleep opportunity instead of chasing a fixed target.
- Keep only the familiar movement included in your taper plan.
- Finalize required gear early enough to resolve problems without panic.
- Follow the practiced nutrition and thirst-led hydration plan unless a clinician advised otherwise.
- Check travel, start time, crew rules, and mandatory kit.
- Pack lighting, chargers, clothing, and foot-care items required by the event or your tested system.
What Not to Do
Avoid adding an unplanned hard workout or compressing missed training into race week. New strength work, aggressive stretching, unfamiliar footwear, tape, food, drink, or last-minute equipment changes can create problems that have not been tested.
Use the 24-hour race gear checklist as a final systems check even if your race is longer.

These studies concern endurance athletes and marathon runners rather than direct comparisons of taper schedules for 24-hour, 48-hour, or multiday races. The article therefore does not infer one optimal schedule for those formats.
Frequently Asked Questions
How long should you taper for a 24-hour race?
There is no ultramarathon-specific duration that is right for everyone. Evidence from endurance and marathon runners supports reducing training before competition, but the timing and size of that reduction should reflect the preceding load, experience, injury or illness, and response to prior tapers.
Should you stop running during an ultra taper?
Not by a universal rule. Some runners retain familiar short sessions while reducing load; pain, illness, or a clinician's advice may call for more rest. Do not copy another runner's frequency or intensity without considering your own training and health.
Can you gain fitness during race week?
Trying to add a large new training stimulus in race week is more likely to add fatigue than solve a preparation gap. Keep decisions consistent with the plan agreed with your coach or clinician, particularly when pain or illness is present.
