What to Do in the
Days After a Big Race
The race is finished. The medal is around your neck. Your body is sore, your nervous system is still buzzing, and somewhere on the drive home you might feel an ache that has nothing to do with your legs.
Post-race recovery is one of the most overlooked phases in an endurance athlete's year. We plan the training block, the gear, the pacing, the fuel, the travel and the race-day logistics. Then the moment the race is done, many runners try to wing the recovery.
The days after a big race are not a passive waiting period. They are a purposeful transition. Your job is not to prove how quickly you can return. Your job is to help your body absorb what it has just done.
“Recovery is training. The two are not opposites, they are one system.”
The way you recover after a big race influences how you return to movement, whether niggles settle or escalate, and whether the next training block begins from a repaired body or a depleted one.

What just happened inside your body
A big race is a major physiological event. Trail and ultra events add extra load because of elevation, eccentric downhill running, uneven terrain, long hours on feet, heat or cold exposure, sleep disruption, travel, and the mental focus required to keep going.
In the hours and days after racing, your body is working hard behind the scenes. Muscle fibres are repairing. Glycogen stores need to be replenished. Fluid and sodium balance may still be shifting. Your immune system can be temporarily altered after prolonged intense effort. Your nervous system may feel wired and tired at the same time.
For women, energy availability matters here. If the race created a large energy deficit, or if the weeks leading in were under-fuelled, recovery can be slower and mood, sleep, appetite, menstrual cycle regularity and injury risk may be affected. This is not a reason to fear big races. It is a reason to respect the recovery window.
What your body is asking for
Food. Fluid. Sleep. Warmth. Gentle movement. A reduction in pressure. Time for inflammation and repair to do their job. Recovery is not about doing nothing forever. It is about not interrupting the repair process too soon.

The return-to-running mistake most runners make
The most common post-race mistake is returning to running because your head is ready before your body is. After a successful race, it is tempting to keep the momentum going. After a disappointing race, it is tempting to try to fix the feeling with another session, another entry or another goal.
But fitness and tissue recovery do not return at the same speed. Your aerobic system may feel ready within days. Your muscles, tendons, bones, connective tissue and nervous system may need longer, especially after a hilly trail race or ultra.
There is no perfect one-size-fits-all formula. Distance matters, but so do elevation, downhill load, weather, fuelling, sleep, training history, menstrual health, perimenopause symptoms, life stress and how hard you had to dig. The better question is not “how many days until I can run?” It is “what signs tell me my body is ready?”
The better return-to-run rule
Return when your body can move well, not just when your motivation returns.
You should be able to walk downstairs normally, move without limping, sleep reasonably, feel your appetite returning, and complete a short walk without soreness worsening afterwards.
If your gait is altered, your resting heart rate feels unusually high, you feel unwell, or soreness is still sharp or increasing, wait.

The first 72 hours: protect the repair window
The first three days after a big race are not the time to test fitness. They are for rehydrating, refuelling, sleeping, letting soreness peak and giving the immune system and nervous system a quieter environment.
On race day evening, aim for a full meal as soon as practical. Include carbohydrate to begin replenishing glycogen, protein to support repair, fluids and electrolytes to replace losses, and enough total energy to tell the body it is safe to recover.
On days one to three, walking is enough. Gentle movement can help circulation and stiffness, but there is no need to turn it into training. Soreness often peaks around day two or three, especially after long descents. That does not mean you are going backwards. It means the repair process is underway.
Days 0 to 3
Do: eat real meals, hydrate steadily, sleep as much as possible, walk gently, elevate legs if swollen, keep warm, and ask for help if you need it.
Avoid: hard training, long walks that become secret workouts, testing pace, heavy strength, aggressive stretching of sore tissue, and making big emotional decisions about your next goal.

The emotional low that nobody warns you about
Post-race blues are real, common and often surprising. You can be proud of yourself and still feel flat. You can have had the best day and still feel teary or lost a few days later. You can achieve the goal and still wonder, “now what?”
This low is not a sign that the race was not worth it. It is often the natural aftermath of months of structure, anticipation, identity and focus suddenly coming to an end. Add physical soreness, disrupted sleep, travel, hormonal shifts, under-fuelling, social comedown and the return to normal life, and it makes sense that your emotional system may need time to land.
Naming it helps: “I am having a post-race low. This is a normal part of coming down after something that mattered.” Then give yourself the same patience you would offer a friend.
“The flatness after a big race is not a sign that the race was not worth it. It is a sign that it mattered.”
Let the emotional landing be part of the recovery. Reflect before you rush. Celebrate before you analyse. Rest before you rebuild.

A simple recovery timeline
Race day evening
Eat as soon as practical. Start with whatever you can tolerate, then move toward a proper meal with carbohydrate, protein, fluids and salt. Keep the evening simple. Warm shower, comfortable clothes, easy food, early bed.
Days 1 to 3
No running. Gentle walking only if it feels good. Sleep, nap, hydrate, eat often, and let soreness move through. If you feel emotionally flat, do not rush to fix it. Let your system come down.
Days 4 to 7
Active recovery. Walking, very easy swimming, gentle bike, mobility, yoga or light stretching. If soreness is settling, a short easy jog may be appropriate for some runners, but only if you are moving normally and it does not create a symptom rebound.
Week 2
Short, easy runs may return if your body is ready. Keep them genuinely easy. No pace targets, no intervals, no hill repeats, no proving. Light strength can return as activation and mobility first, not heavy loading.
Weeks 3 to 4
Gradually build frequency before intensity. Keep most runs easy. Reintroduce light strides or gentle hills only when your normal easy runs feel normal again. If your heart rate is unusually high, sleep is poor, or your mood is heavy, stay patient.
Weeks 4 to 8
For bigger trail races and ultras, this is often where real training begins to return. The longer and hillier the race, the more conservative the rebuild. Start with consistency, then add load. Do not stack intensity, long runs and heavy strength all in the same week too soon.

What to eat in the days after
Post-race nutrition is not about restriction, compensation or “getting back on track.” It is about repair. Your body has just spent hours drawing on stored carbohydrate, breaking down muscle tissue, losing fluid and salt, and managing stress hormones. It needs enough energy to rebuild.
Food-first recovery
Carbohydrate: replenishes glycogen and supports the immune and hormonal systems.
Protein: supports muscle repair and adaptation.
Fluid and electrolytes: help replace sweat losses, especially after hot, humid or long races.
Colour and variety: fruit, vegetables, wholegrains, dairy or fortified alternatives, legumes, eggs, fish, meat or plant proteins all help create a recovery environment.

Female-specific recovery cues
The recovery conversation for women needs to include more than sore legs. Energy availability, menstrual health, iron status, pelvic floor symptoms, perimenopause, sleep, stress and caring load can all change how recovery feels.
Menstrual cycle
If your period arrives straight after a race, or if symptoms feel stronger than usual, reduce the pressure to bounce back. Heavy bleeding, low iron, cramps, sleep loss and under-fuelling can all make recovery feel harder. If your cycle becomes irregular or disappears after a training block, seek support.
Perimenopause and menopause
Sleep disruption, hot flushes, joint aches, mood changes and longer recovery windows can all show up in midlife. This does not mean you are less capable. It means recovery may need to be more deliberate, with strength, protein, sleep support and lower “junk intensity” becoming even more important.
Pelvic floor and core symptoms
Leaking, heaviness, dragging, pelvic pain or a sense of pressure after a race are not things to ignore. They are signs to reduce impact and seek guidance from a women’s health physiotherapist.

Before you sign up for the next race
The post-race window can make everything feel urgent. If the race went well, you want more. If it did not go to plan, you want another chance. Both responses are understandable. Neither needs to be acted on immediately.
Give yourself time to land before you choose the next thing. Let your body recover enough that your next goal is chosen from clarity, not adrenaline, comparison, disappointment or fear of losing fitness.
Reflection prompts
- What am I proud of that has nothing to do with the result?
- What did this race ask of me physically, mentally and emotionally?
- What did I learn about my fuelling, pacing, gear, mindset and support?
- What does my body need before I ask it for another build?
- Am I choosing the next race from excitement, or from urgency?

When to seek extra support
Most post-race soreness and emotional flatness will settle with time, food, rest and gentle movement. But some signs deserve medical or professional support.
Do not ignore
- Pain that is sharp, worsening, one-sided, or changes the way you walk.
- Dark cola-coloured urine, severe swelling, confusion, fainting, chest pain or shortness of breath.
- Fever, ongoing vomiting, diarrhoea or inability to keep fluids down.
- Persistent dizziness, extreme fatigue or signs of illness after the race.
- Menstrual changes, missed periods or heavy bleeding after a training block.
- Pelvic heaviness, leaking, pain or pressure with walking or returning to running.
- Low mood that feels intense, unsafe, or does not begin to lift after a couple of weeks.
Her Trails coaching cue
Treat sleep like training. The first few nights post-race are not an afterthought. They are one of the most powerful recovery tools available to you. Protect them where you can.
The takeaway
You do not need to rush back to prove the race made you stronger.
The race already asked enough of you. Let the recovery complete the work.
rest well, rebuild slowly
