Race Tapering: How to Arrive in Top Shape on Marathon or Race Day
What tapering really is, how long it should last, and how to manage training and nutrition in the final weeks before a running race.
Written by the editorial team at Velunite
After weeks of training, the final phase before a race is often the most mismanaged: caught between the urge to squeeze in one more hard session and the fear of showing up already tired, many runners ruin three months of work in the last two weeks. Tapering exists precisely to avoid that mistake.
What tapering actually is
Tapering is the progressive reduction of training volume in the final weeks before a race, while keeping some intensity in the mix. The goal isn't to "rest" in the sense of stopping, but to let the body clear accumulated fatigue while holding onto the adaptations built over months of work.
How long it should last
For a marathon, a 2-3 week taper is the most common approach: volume drops by about 20-30% in the first week, further in the second, and in the final week it drops noticeably, keeping only short sessions with a few pickups to stay "sharp". For shorter distances, like a 10K or half marathon, tapering can last as little as 5-10 days.
The most common mistake: cutting intensity too
Many runners, while cutting mileage, also strip out any quality work. That's a mistake: keeping a few strides or short race-pace repeats, even in the final week, helps the legs stay reactive, while cutting everything often leaves you feeling "heavy" or flat on race day.
Nutrition in the final days
In the 2-3 days before the race, slightly increase carbohydrate intake without overhauling your usual diet: the goal is to show up with full glycogen stores, not to experiment with new foods. This is also the time to confirm what you'll use during the race itself, gels and electrolytes included, so you don't discover intolerances or digestive issues on race day itself.
Managing the mind as much as the legs
Tapering is also a mental challenge: with less training, there's more time to think about the race, and it's not unusual to feel more nervous or even convinced you've lost fitness. That feeling is normal and temporary: trust the work done in the previous months, and use these days to sleep well, sort out race-day logistics, and arrive rested rather than overtrained.
Recommended products
Energy gels for running: test these during the taper, not on race day, to find out which formats and flavors your stomach handles best.
Electrolyte supplements: especially useful for long races or hot conditions, worth trying in advance during your final training sessions.
