How to taper for a half marathon (a 2-week half marathon taper plan)
A half marathon taper is 7 to 14 days of less running, a little speed, and no heroics. A day-by-day half marathon taper plan, including the lifting.
A half marathon taper is the last 7 to 14 days before the race, when you cut your running volume, keep a little race-pace work, and stop doing anything new. Most runners need about ten days. The fitness is already built. The taper just clears enough fatigue for you to use it.
Below: how to taper for a half marathon, how long, how much to cut, a full half marathon taper plan for the last two weeks, and what to do with the gym. If your build got messy, a coach that adapts when life gets in the way can rebuild the last weeks around the race date.
Why a half marathon taper works
A training block works by stacking stress. By the end of it you're fitter than you've ever been, and more tired than you realize. The taper removes the tired part.
The research on tapering is consistent on the basics. A meta-analysis of 27 studies in competitive athletes found the most effective taper lasted about two weeks, with training volume cut by 41–60%, while intensity and frequency stayed the same (Bosquet et al., 2007).
The taper is the final phase of the way your training is structured over months: base, build, peak, taper. Any decent plan, including a ready-made hybrid schedule, ends with one. If yours just stops abruptly the week before, or doesn't change at all, it's skipping the bit that turns training into race day.
How long should a half marathon taper be?
For most runners, 7 to 14 days.
- About 7 days: newer runners on lower mileage, or anyone whose long run peaked at 10 miles or so.
- About 10 days: the sweet spot for most.
- About 14 days: higher-mileage runners, or anyone coming off a big, tiring build.
That's shorter than a marathon taper, which usually runs two to three weeks, because a half build carries less accumulated fatigue. A big observational study of recreational marathoners found strict tapers of up to three weeks were associated with better finish times (Smyth & Lawlor, 2021), but that was the full marathon. Don't copy a marathon taper for a half. Three weeks of easing off before 13.1 miles is usually more rest than the race needs.
How to taper for a half marathon: the rules
Every race-week taper follows the same logic. For a half:
- Cut volume gradually. Total weekly running drops across the taper, by roughly half by race week. Gradual beats sudden; a review of taper research found progressive tapers did better than abrupt step cuts (Mujika & Padilla, 2003).
- Keep intensity. Short efforts at goal pace or a bit faster stay in the plan. They keep your legs sharp.
- Keep frequency. If you run four days a week, keep running four, just shorter.
- Last long run about two weeks out. The weekend before race week gets a shorter, easy long run.
- Nothing new. No new shoes, gels, workouts, or stretching routines.
A taper is not the same as a lighter week in the middle of a block. A deload cuts everything a bit to set up more training. A taper cuts volume harder and keeps race-pace work, to set up one performance.
A half marathon taper plan (two weeks)
This assumes you've been running four or five days a week and lifting twice. Adjust distances to your own training. The pattern matters more than the numbers.
Two weeks out
| Day | Run | Lift |
|---|---|---|
| Mon | Rest or easy short run | Last full lower-body session, moderate |
| Tue | Quality session: shortened version of a familiar workout, e.g. 3 × 2 miles at goal pace | — |
| Wed | Easy | Upper body, normal |
| Thu | Easy with 4–6 strides | — |
| Fri | Rest | Light full body or mobility |
| Sat | Easy | — |
| Sun | Long run, shorter than peak, easy | — |
Half marathon taper week (race week)
| Day | Run | Lift |
|---|---|---|
| Mon | Easy, short | Light upper body or mobility, 20–30 min |
| Tue | Short sharpener: 10–15 min easy, then 3–4 × 3 min at goal pace, easy jog between | — |
| Wed | Easy, short | — |
| Thu | Easy with 4 strides | — |
| Fri | Rest | — |
| Sat | 15–20 min very easy with 3–4 strides, or rest | — |
| Sun | Race | — |
That's a taper week for a half marathon: everything still happens, nothing is hard, and the only effort with any bite is short and early in the week.
What to do with the gym during a taper
Lifting is where hybrid athletes accidentally sabotage the taper. Heavy squats or deadlifts too close to race day leave your legs heavy in a way no amount of easy running will fix.
The practical rules:
- Last real lower-body session: about 7 to 10 days before the race.
- After that: light upper body, core and mobility only. Short and familiar.
- Race week: one short, light session early, or nothing. Nothing that makes you sore.
You won't lose strength in ten days of lighter lifting. You'll pick up where you left off after the race, and resume progressing week to week once you've recovered.
The final days before the race
Sleep. The night before the race rarely goes well because of nerves. The two or three nights before matter more. Bank sleep then.
Food. Eat normally, with a bit more carbohydrate in the last day or two, and nothing unfamiliar. Your race-morning breakfast should be something you've eaten before a long run.
Kit. Lay it out the night before. Shoes you've run in. Clothes you've run in. Gels you've used in training.
Pacing plan. Decide your opening pace now, while you're calm. The first mile on race day will feel ridiculously easy because you're tapered. That's the taper working, not a sign to go faster.
Common half marathon taper mistakes
- The guilt workout. Running a hard session four days out because you feel slow. You won't get fitter in four days. You will get more tired.
- Over-tapering. Barely running for two weeks. You'll feel stale, not fresh.
- Testing your fitness. A time trial or parkrun race in the final week. Save it for Sunday.
- Making up missed runs. If you lost a week to illness in the build, the taper is not the place to make it up. Run the taper you were given.
- Panicking about how you feel. Heavy legs and restlessness are normal during a taper. Everyone gets them. They're gone by race morning.
Where the taper fits in the bigger plan
A half marathon build is usually three or four blocks: base, build, peak, taper. If you've ever wondered what is a mesocycle, each of those blocks is one: a few weeks with one job, ending in a lighter week or, at the very end, the taper.
If the half is a stepping stone to a marathon, the same skeleton stretches out across longer phases, and the marathon taper at the end is longer too. That stretched-out version is what marathon training blocks are, and the logic behind block periodization more generally: one focus per phase, built in sequence, with recovery between.
How exrsz handles the taper
exrsz builds your half marathon plan around your race date, so the taper is on the calendar from day one, with running and lifting cut together. It adapts each week to how you actually trained, and if you miss sessions in the build it reshuffles them rather than cramming them into race week.
FAQ
How long should a half marathon taper be?
Usually 7 to 14 days. About ten days suits most runners; newer runners on lower mileage can taper for a week, and higher-mileage runners coming off a big build may want the full two weeks.
What should I do during taper week for a half marathon?
Run your usual number of days but shorter, keep one short session with a few goal-pace efforts early in the week, add strides, and rest the day before or do a very short shakeout. No new workouts, shoes or food.
How much should I cut mileage in a half marathon taper?
Aim for roughly half your usual weekly volume by race week, cut gradually. A meta-analysis of taper studies found volume cuts of 41–60%, with intensity kept, worked best (Bosquet et al., 2007).
When should my last long run be before a half marathon?
About two weeks before race day. The weekend before the race gets a shorter, easy long run instead.
Should I lift weights during a half marathon taper?
Lightly. Do your last real lower-body session 7 to 10 days out, then stick to light upper body, core and mobility so your legs are fresh on race day.
