Quick summary
- First hour: keep walking, put on warm clothes, drink to thirst and eat carbohydrate with some protein.
- First 48 hours: rest, walk gently, sleep, and eat well. Soreness usually peaks 24–72 hours after the race.
- Week 1: no running for at least 3–5 days, then short, very easy runs only if you feel good.
- Weeks 2–3: gradually rebuild easy running. Hold off on hard workouts and racing.
- Get help for chest pain, confusion, very dark or cola-coloured urine, or pain that gets worse instead of better.
Crossing the finish line is the end of the race but the start of recovery. A marathon causes muscle damage, depletes your energy stores, stresses your immune system and leaves you short on sleep. Recovering well means you'll feel better sooner, avoid injury, and come back stronger for your next goal.
The first hour after the finish
- Keep moving. Walk for 10–15 minutes after you finish rather than sitting or lying down straight away.
- Get warm. Put on dry, warm clothes as soon as possible. Your body temperature can drop quickly once you stop.
- Drink to thirst. Water or a sports drink. There's no need to force down large amounts.
- Eat. Within an hour or so, have something with carbohydrate and some protein: a recovery drink, a sandwich, yoghurt and fruit, or chocolate milk all work.
- Check yourself. Feeling tired, sore and emotional is normal. Feeling confused, faint or very unwell is not; go to the medical tent.
The first 48 hours
- Rest, but don't stay completely still. Gentle walking helps you feel less stiff.
- Sleep. It's when most repair happens. Nap if you can.
- Eat well. Regular meals with carbohydrate to refill energy stores, protein (roughly 20–40 g per meal) for muscle repair, and plenty of fruit and vegetables.
- Expect soreness. Delayed-onset muscle soreness usually peaks 24–72 hours after the race. Stairs going down are the classic giveaway.
- Go easy on alcohol. It can affect sleep and rehydration.
Gentle massage, compression clothing and a warm bath may help you feel better; none is essential. Avoid deep or aggressive massage in the first couple of days while muscles are damaged.
When to start running again
There's no fixed rule, but a common approach is a "reverse taper": rebuild gradually over about two to three weeks, the opposite of the taper you did before the race.
| Days after the marathon | What to do |
|---|---|
| 1–3 | No running. Walking, gentle mobility, rest |
| 4–7 | Optional: 2–3 short runs of 20–30 minutes at a very easy effort, only if you feel good. Cycling or swimming are good alternatives |
| 8–14 | Easy running only, building from about 40% to 60% of your usual weekly distance. No speedwork |
| 15–21 | Easy running up to 70–80% of usual. Add strides; one light session at the end if you feel fully recovered |
| 22+ | Return to normal training, starting with shorter workouts |
If you're still sore, limping or feel unusually tired, wait longer. Most runners feel recovered in their legs before they are actually recovered. If you followed our sub-4 hour marathon training plan, this is the time to rest before planning the next block.
Soreness or injury?
General soreness is normal. Pain that suggests injury is not. See a doctor or physiotherapist if you notice:
- Pain in one specific spot, especially on a bone, that hurts when you press it
- Pain that gets worse over several days instead of better
- Swelling, or a limp that doesn't ease
- Pain that changes how you walk or run
Seek urgent medical help if you have chest pain, breathlessness, confusion, fainting, or very dark, cola-coloured urine, or if you can't pass urine. These can be signs of serious conditions that need prompt treatment.
The post-marathon blues
Many runners feel flat or low in the days and weeks after a marathon. You've lost the structure, goal and routine that shaped the last few months. This is common and usually passes.
What helps: rest guilt-free, reflect on what went well, spend time with people you trained with, and only pick a next goal once you're physically recovered.
When can you race again?
- 5K or 10K: most runners can race a short distance three to four weeks after a marathon, if fully recovered.
- Half marathon: four to six weeks is a sensible minimum.
- Another marathon: most coaches suggest at least 12–16 weeks between hard marathon efforts, with a proper training block in between.
FAQ
How long does it take to recover from a marathon?
Most runners feel recovered enough to run easily within one to two weeks, and are ready for normal training after about three to four weeks. Full recovery of muscle and energy systems can take longer, especially after a very hard race.
Should I run the day after a marathon?
Most runners shouldn't. Rest or walk for the first few days, then start with short, very easy runs once soreness has eased.
What should I eat after a marathon?
Within an hour or so, eat carbohydrate with some protein. Over the next few days, eat regular, balanced meals with plenty of carbohydrate, protein, fruit and vegetables to support repair.
Why are my legs so sore two days after a marathon?
This is delayed-onset muscle soreness, caused by muscle damage from the race. It usually peaks 24–72 hours afterwards and eases over several days. Gentle walking helps.
Is it normal to feel sad after a marathon?
Yes. Many runners feel low after a big race because the goal and routine they focused on for months has ended. It usually passes within a couple of weeks. If low mood persists, talk to someone you trust or a health professional.
