Post half marathon recovery: what to do in the days after

Post half marathon recovery, in one line: a couple of days of walking, eating and sleeping, a few days of short easy runs, then normal training again somewhere in the second week. Heavy lower-body lifting comes back last, not first. That's the whole plan. Most people get it wrong by doing too much in week one because they feel fine on Tuesday.

You ran 13.1 miles. Your legs know. Your ego may not have been told yet.

Below is a day-by-day post half marathon recovery plan, how the lifting fits back in, and what changes it. If you run and lift, this is exactly the week where two separate apps start fighting, which is why a running app that also coaches lifting is worth having for the comeback as much as the build.

One note up front: this is coaching practice, not medical advice. Normal post-race soreness fades over a few days. Sharp pain, swelling, pain that changes how you walk, or anything that gets worse instead of better is a reason to stop running and see a professional.

Post half marathon recovery: the short version

Here's what the week after usually looks like for someone who raced hard and also lifts:

These are coaching conventions, not rules. A gentle first half run by effort needs less. A flat-out PR attempt in heat needs more. If you're following a half marathon training plan, the week after the race should already be written in as recovery, not left blank for you to fill with guilt.

There's an old rule of thumb that you need one easy day for every mile you raced, which would make it roughly two weeks without hard running after a half. It isn't science. It's a decent reminder that "I feel fine" and "I've recovered" are different sentences.

If you're still building toward the race, start with more on how to train for a half marathon. This post picks up at the finish line.

Why some halves take longer to recover from

Two people can run the same course and need very different weeks afterwards. The usual differences:

• ›How hard you ran. A race effort costs more than a long run at easy pace over the same distance. A PR attempt costs the most.
• ›How you fueled. Running a half on an empty tank tends to make the last few miles, and the next few days, feel worse. Knowing how many gels for half marathon day you need is part of recovery, just done in advance.
• ›How long you were out there. Someone near the average time for a half marathon, female or male, spends more time on their feet than someone running 1:30. More time on feet, more pounding. Neither is easier. They're differently hard.
• ›How you paced it. Going out too fast and hanging on for the last 5K is a special kind of damage. Learning how to find your goal pace is the cheapest recovery tool there is.
• ›The course and the weather. Downhills, heat and cambered roads all add to the bill.
• ›What you were doing before. If the race came at the end of a well-built block with a proper taper, you'll bounce back faster than if you squeezed it into a heavy lifting week.

The first few hours

Don't stop moving the second you cross the line. Walk for a bit, collect your stuff, get warm clothes on. Then:

• ›Drink. Water, a sports drink, whatever's on offer. Then keep sipping over the next few hours.
• ›Eat something with carbs and protein once your stomach agrees. The banana and the bagel in the finish area count.
• ›Have a real meal later. The evening after, eat a normal, carb-forward dinner. It's the same kind of meal as what to eat the night before a long run: familiar, filling, nothing heroic.

Days 1 to 3: do less than you think

The first few days are for walking, eating and sleeping.

• ›Walk. Short walks loosen things up better than lying on the sofa feeling sorry for your quads.
• ›Run only if it feels genuinely easy. Many runners skip running entirely for two or three days after a hard half. Others do a 15 to 20 minute shuffle on day two or three. Both are fine. Pushing through a limp is not.
• ›Stairs will be funny. Especially going down. That's normal soreness, and it usually peaks a day or two after the race.
• ›Upper-body lifting is fine if you feel like it. Keep it light and short. You're moving, not training.
• ›Sleep more than usual if your life allows it. It's the boring answer and it's the right one.

Some runners like foam rolling, massage or compression in this window. If it makes you feel better, do it. Just don't count on any of it to replace time.

Days 4 to 7: easy running comes back

By the middle of the week, most people can run easy again without counting every step.

• ›Keep runs short and conversational. 20 to 40 minutes. Full sentences, no watch-checking.
• ›No intervals, no tempo, no long run. Not even "just a few strides to see how the legs feel" until late in the week.
• ›Bring lifting back gradually. Full body, lighter loads, fewer sets. Leave several reps in the tank.
• ›Hold off on heavy squats and deadlifts. Your legs just did 13.1 miles of eccentric work. A max effort lower-body day now is a bad trade.

If you were a complete beginner, the timeline stretches. A first half off a short build, like couch to half marathon in 12 weeks, often needs a full easy week before running feels normal again.

Week 2: back to normal, mostly

In the second week, most people who raced hard can return to their normal easy volume and add one light quality session late in the week, like a short fartlek or some relaxed strides.

Lifting can return to moderate lower-body work. Heavy, PR-adjacent work waits until your easy runs feel easy again and nothing is still sore.

The test is simple: if your easy pace at a normal effort is back where it was before the taper, and you're not stiff on stairs, you're close. If your easy runs feel heavy and sluggish, give it a few more days. There's no medal for coming back early.

Lifting after a half marathon

This is the part most half marathon recovery advice skips, because it assumes you don't lift.

The principle is the same as during the build: running and lifting share the same legs. After the race, the legs are the bottleneck. Upper body can come back almost straight away. Heavy lower-body work should come back last, after your easy runs feel easy again.

Food in the days after

You don't need a special diet in race week plus one. You need to eat enough.

What to eat after a half marathon mostly comes down to normal meals with carbs and protein, and enough fluid, for the few days after the race. Don't use the week after as the moment to start a big calorie deficit. Your legs are rebuilding and your appetite may be up. That's expected.

And if you carb loaded before the race and the scale went up a little, that's mostly the extra carbohydrate and water you stored on purpose. Carb loading is supposed to do that. It comes back off as you return to normal eating.

Planning what's next

A lot of runners make their worst decision of the year in the week after a half: signing up for something big while still on a post-race high, or diving straight back into hard training to "not lose fitness".

A week or two of easy running is a cheap trade. A month off with an injury is not.

A sensible order:

1. ›Recover (the two weeks above).
2. ›Look honestly at the race. What went well, what went sideways, was the pacing right?
3. ›Pick the next goal. Another half, a marathon, a strength block, a Hyrox. Each needs a different next block.
4. ›Rebuild from easy volume, not from where you peaked.

Common mistakes

• ›Racing the Tuesday parkrun. You feel fine. You aren't.
• ›Heavy squats on day three. The fastest way to make a four-day recovery into a ten-day one.
• ›Skipping food because the race is over. Recovery needs fuel too.
• ›Running through a limp. Soreness is normal. Pain that changes how you move is not. See a professional.
• ›Starting the next plan at peak volume. Rebuild from easy mileage.

How exrsz handles this

exrsz builds a periodized plan from your goal, your schedule, your level and your equipment, with running and lifting in one plan. After race day, the next weeks adapt to how you trained, so recovery is planned instead of improvised, and missed sessions get reshuffled rather than crammed in.

FAQ

How long does post half marathon recovery take?

For most people who raced hard, a few days of rest and walking, then easy running, with normal training back in the second week. Heavy lower-body lifting usually comes back last.

When can I run again after a half marathon?

Many runners do a short, very easy run two or three days after the race, and some take a few days off completely. Either is fine as long as it genuinely feels easy and nothing hurts beyond normal soreness.

What does a post half marathon recovery plan look like?

Walking and rest for the first two or three days, short easy runs for the rest of the week, then normal easy volume and one light quality session in week two. Lifting returns upper body first, heavy legs last.

Can I lift weights after a half marathon?

Yes. Light upper-body work is fine within a few days. Bring lower-body lifting back gradually through the first week and save heavy squats and deadlifts until your easy runs feel normal again.

Is it normal to be sore for days after a half marathon?

Some soreness for a few days is common, especially on stairs. If pain is sharp, getting worse, or changes how you walk, stop running and see a professional.
