AFTER THE FINISH LINE: MY ADVICE FOR YOUR POST MARATHON RECOVERY

Published: 20/04/2026 | By: Tommy Trees

You’ve just finished a marathon – huge moment. But now what? Simple: recovery. How you approach it can make all the difference in how quickly you feel like yourself again and how smoothly you return to training. To take the guesswork out, coach and running ambassador Tommy Trees has put together a simple, no-nonsense guide on exactly what to do after race day – from refuelling and rehydrating to knowing when you’re ready to run again. Got a race coming up, or just crossed the line? This is well worth a read.

Finishing a marathon is a huge achievement, whether it’s your first or your tenth, you should take real pride in it! It’s completely normal to feel physically drained, sore and even a little flat once the race is over. Your body has just gone through a significant amount of stress and post-race fatigue is part of the process. This is exactly why structured recovery matters.

Giving your body the time and support it needs to repair muscle, reduce injury risk and restore energy levels will set you up far better for your next block of training. It’s also important to remember that recovery isn’t one size fits all. How quickly you bounce back will depend on your training background, race effort and overall lifestyle, so the key is to listen to your body and not rush the process.

IMMEDIATE RECOVERY – POST-RACE

The moment you cross the finish line, take a second to acknowledge what you’ve just achieved. Completing a marathon is a huge milestone and it’s important to enjoy that moment. Whether that’s celebrating with friends, taking photos or even having a drink, you’ve earned it. At the same time, try to keep recovery in mind. It looks something like this for me:

• Start rehydrating with small, regular sips, ideally using an electrolyte drink to help replace what you’ve lost during the race
• Aim to get some food in early, even if it’s something simple, focusing on carbohydrates and protein! Keep fluids going consistently rather than all at once
• If you are celebrating with a drink, just please make sure to balance it with water alongside it

“TAKE A SECOND TO ACKNOWLEDGE WHAT YOU’VE JUST ACHIEVED. COMPLETING A MARATHON IS A HUGE MILESTONE AND IT’S IMPORTANT TO ENJOY THAT MOMENT.”

THE FIRST 24–48 HOURS: REST, REFUEL, REHYDRATE

The first couple of days after your marathon are where the real recovery happens. What you do here has a big impact on how quickly you bounce back.

Nutrition: Prioritise carbohydrates and protein to support muscle repair and restore energy levels. As a rough guide, aim for around 1.6 to 2.2 grams of protein per kilogram of bodyweight per day, alongside plenty of carbohydrates to replenish what you’ve used during the race. Keep meals simple and regular rather than forcing large portions all at once.

Hydration: Hydration is key, but it doesn’t need to be complicated. A simple way to monitor this is by checking your urine colour. You’re aiming for a pale yellow colour, which indicates you’re well hydrated. Darker urine is a sign you need to increase your fluid intake. Keep sipping fluids consistently throughout the day rather than drinking large amounts in one go.

Sleep and Rest: Sleep is your biggest recovery tool. I always tell runners to aim for 8 to 10 hours where possible in the days after a marathon. This is when your body is repairing muscle tissue, restoring energy and supporting your immune system. You’re actually more vulnerable to illness during this period, so prioritising sleep is key. It’s also worth noting that sleep can feel a bit disrupted after a race due to adrenaline and fatigue, so don’t stress if the first night isn’t perfect, just focus on getting quality rest over the following days.

Active Recovery: This might feel counterintuitive, but complete rest isn’t always the best option. Light movement can actually help reduce stiffness and improve how you feel. Something as simple as a short walk, gentle stretching or even an easy swim or cycle can make a big difference. Keep it relaxed and low effort, the goal isn’t to train, it’s to help your body recover.

Recovery Tools: What Actually Helps

There’s no magic fix when it comes to recovery, but the right tools can definitely help you feel better and move more freely in the days after a marathon. I tend to keep things simple and use what works consistently rather than overcomplicating it.

Hot Bath

A hot bath is one of the easiest ways to relax tight muscles and switch off mentally after a race. The heat helps increase blood flow, which can ease stiffness and support the recovery process by delivering more oxygen and nutrients to the muscles. I usually keep baths to around 10 to 15 minutes and not too hot, especially in the first 24 hours.

Sauna

Saunas can offer similar benefits. The heat exposure helps improve circulation, promote relaxation and can support recovery when used appropriately. I’d typically keep sauna sessions to around 10 to 20 minutes, depending on how you’re feeling, and always make sure you’re well hydrated before and after.

Massages

Sports massage can be really effective for reducing muscle tightness and improving circulation. That said, timing matters. I’d avoid anything too deep immediately after the race when your muscles are already fatigued. Lighter, more gentle work in the first few days tends to be more beneficial, with deeper massage coming later once soreness settles.

Compression Gear

Compression socks or tights can help support circulation and reduce swelling, particularly if you’re travelling or spending time on your feet after the race. I often recommend using them in the first 24 to 48 hours, especially if your legs are feeling heavy.

Foam Rollers and Massage Guns

These are some of the most practical tools you can use, and ones I come back to consistently. Foam rolling is great for myofascial release, which essentially means helping to reduce tension in the connective tissue around your muscles. After a marathon, this can improve range of motion, reduce stiffness and help your muscles feel less restricted, especially in areas like the calves, quads and glutes. Massage guns work in a similar way by increasing blood flow and stimulating the muscle, which can help reduce tightness and promote recovery.

WHEN TO RUN AGAIN: TIMELINES AND SIGNALS

One of the most common questions after a marathon is when to start running again. The honest answer is that it depends on the individual, but there are some general guidelines I tend to follow and recommend.

0–5 days

The focus here is recovery, not training. Try to include light movement each day, even if it’s just short walks or gentle mobility. It might feel counterintuitive, but staying completely still often makes stiffness worse. Keep everything very low effort and let your body settle.

5–10 days

If you’re feeling good, you can start to introduce some very easy running. Keep it short, relaxed and at a conversational pace. This isn’t about building fitness, it’s about reintroducing movement and seeing how your body responds.

10–20 days

This is where you can begin to add a bit more structure back into your week. You might increase the duration of your runs and build consistency, but intensity should still stay low. Think controlled, steady running rather than anything too demanding.

After 21 days (3 weeks)

If recovery has gone well, this is where I’d look to return to a more normal training structure. You can start to reintroduce some intensity, but keep it gradual. Short strides or light efforts are a good starting point before progressing back into full sessions.

SIGNS YOU’RE READY

• No lingering soreness or tightness
• Energy levels feel back to normal
• Easy running feels comfortable and controlled

If something feels off at any point, give it more time. A few extra days of patience is always better than setting yourself back with an injury.
