- Expect soreness to peak one to three days after the race, especially in the quads and glutes.
- Eat protein and carbohydrate, rehydrate and keep moving gently in the first few hours.
- Easy movement such as walking or cycling helps more than lying on the sofa.
- Return to easy training after a few days and hold off hard sessions for around a week.
- Dark, cola-coloured urine with severe muscle pain needs urgent medical attention.
What a HYROX race does to your body
HYROX is unusually hard on the muscles for an endurance event. The lunges and wall balls in particular involve a lot of loaded lowering under fatigue, which is exactly the type of work that causes muscle soreness. Add 8 km of running, heavy sleds and burpee broad jumps, and most people wake up the next day walking down stairs sideways.
You will also have used a large share of your stored carbohydrate, lost fluid through sweat and quite possibly slept badly the night before. Your nervous system may feel flat for a few days. All of this is normal and resolves with sensible recovery.
Muscle soreness usually peaks somewhere between one and three days after the race, then fades over the following days. The guide to DOMS explains what is going on and why it is not a sign of damage you need to worry about.
The first few hours
Once you cross the line, the priorities are simple:
- Keep walking for a few minutes rather than sitting down immediately.
- Put on warm, dry clothes. Venues can feel cold once you stop moving.
- Drink water or a sports drink, and keep sipping over the next few hours.
- Eat something within an hour or so, ideally with some carbohydrate and protein.
- Have a proper meal within a few hours, with a good portion of protein and carbohydrate.
Around 20 to 40 g of protein at that meal is a sensible target for most people. Celebratory drinks are understandable, but alcohol on an empty, dehydrated stomach hits harder than usual and does your sleep no favours. Eat first, drink water alongside and keep it moderate.
Days one to three
This is when soreness is at its worst. It is tempting to do nothing at all, but gentle movement usually helps you feel better sooner.
- Walk: 20 to 40 minutes at an easy pace, once or twice a day.
- Easy cycling or swimming if you enjoy them, with no intensity at all.
- Gentle mobility for hips, quads, hamstrings and calves.
- Normal meals with protein at each, plus plenty of fluids.
- As much sleep as you can manage. Sleep is where most recovery happens.
The guide to active recovery has more ideas. Foam rolling, massage, compression and ice baths may make you feel better, and there is little harm in them if you enjoy them, but none of them replaces sleep, food and easy movement.
Getting back to training
For most people, a sensible return looks like this:
- Days 1 to 3: walking, easy cycling, mobility. No training sessions.
- Days 4 to 7: easy runs and light strength work if soreness has mostly settled. Nothing hard.
- Week 2: normal training with moderate intensity, building back towards your usual week.
- From week 3: full training, with a new block planned around what the race taught you.
Listen to how you feel rather than following dates blindly. If you are still very sore or unusually tired at the end of the first week, take a few more easy days. Fatigue after a race can linger longer than the soreness, especially if you raced hard or travelled.
Use this quieter week to review the race. Write down your splits, what went well, what went badly and what surprised you. It is much easier to plan a good next block while the race is fresh in your mind, and it gives the easy week a purpose.
If you train in classes, go back when you feel ready but tell your coach you raced recently. Every class at Lycan Strength is scalable, so a coach can keep the session light while you get back into routine.
Warning signs that need medical help
Normal soreness improves day by day. Some symptoms are not normal and need attention quickly. Seek urgent medical help by calling NHS 111, going to A&E or calling 999 in an emergency if you notice:
- Dark brown or cola-coloured urine, especially with severe muscle pain, swelling or weakness. This can be a sign of rhabdomyolysis, a serious condition where muscle breakdown affects the kidneys.
- Muscle pain that is extreme and out of proportion to what you did, or that keeps getting worse after 48 hours.
- Chest pain, fainting, severe breathlessness or palpitations.
- Confusion, extreme nausea or vomiting, or being unable to keep fluids down.
These are rare, but they matter. Do not wait to see if they settle.
Rhabdomyolysis is more likely after unusually hard or unfamiliar exercise, especially with dehydration, heat or illness. Racing well hydrated and building up to race-level training gradually are the best protection.
Soreness or injury?
General muscle soreness is spread across a muscle, feels achy rather than sharp, and eases gradually. Injury pain is more likely to be sharp, focused in one spot, linked to a specific moment in the race, or to come with swelling or bruising. Pain in a joint, such as the knee, or in a tendon, such as the Achilles, is also worth watching closely.
If a pain is not improving after a few days, or it changes how you walk or run, get it assessed. Lycan Strength has on-site physiotherapy, starting with a full assessment to find the cause, with 20% off for members. The guide to HYROX injury prevention covers the most common problems and how to avoid them next time, and eating for recovery covers the food side in more depth.

Questions
How long does it take to recover from HYROX?
Most people feel sore for two or three days and are back to easy training within a week. Full training usually resumes in the second or third week.
Is it normal to be very sore after HYROX?
Yes. The lunges and wall balls in particular cause a lot of muscle soreness, which usually peaks one to three days after the race.
When can I run again after HYROX?
An easy run from around day four is fine for most people if soreness has mostly settled. Avoid hard running for about a week.
When should I worry about pain after HYROX?
Seek urgent help for dark urine with severe muscle pain, chest pain or fainting. See a physio if a pain is sharp, localised or not improving after a few days.
