After the marathon: a 7-day recovery plan

You trained for months, you ran 42.2 km, and now your legs feel like someone else's. What you do in the next seven days matters more than most runners think: recover well and you keep most of your fitness and come back hungry; rush it and the next weeks become a grind of tiredness and small niggles.

Here is a day-by-day plan. Treat it as a template, not a prescription. If a day feels too easy, that is the point.

Day 0: the first hours after the finish
Keep walking for 10 to 15 minutes after you cross the line. Stopping dead lets blood pool in your legs and makes the stiffness worse. Change into dry clothes as soon as you can, then eat: a mix of carbohydrate and 20 to 30 g of protein within the first hour or two helps refill what you burned. Drink little and often rather than litres at once. Put your legs up in the afternoon, and skip the long hot bath tonight. A short lukewarm shower and an early night do more.

Days 1 and 2: move, but do not train
The soreness usually peaks between 24 and 48 hours after the race, so the second morning is often the worst. That is normal. Stairs will be slow and sitting down will take negotiation.

Your job on these two days is gentle movement, not exercise: a 20 to 30 minute walk, an easy spin on a bike, or a swim if you have access to a pool. Add 10 minutes of relaxed mobility in the evening, moving each joint through its range without forcing anything. Eat properly, put protein in every meal, and aim for at least eight hours of sleep. Most of the repair happens while you are asleep.

Days 3 and 4: an easy reintroduction
By day three the worst of the stiffness has usually passed. You can start reminding your body what running feels like, as long as "easy" really means easy:

• 20 to 30 minutes of very easy jogging, or alternate two minutes of walking with two of jogging
• Flat, soft ground where possible; save hills and trails for next week
• 10 to 15 minutes of bodyweight strength: glute bridges, calf raises, split squats, two sets of each
• A few minutes of self-massage with a foam roller or a ball on the calves and thighs, light pressure only
• Keep the protein and the water going; recovery does not stop because the soreness did

If the first jog feels wrong, walk instead and try again tomorrow. Nothing is lost by waiting a day.

Days 5 to 7: back to a rhythm, not a plan
Run every other day for 30 to 40 minutes at a conversational pace. No speed work, no long run, no racing anyone to the lamp post. The point is to restore the rhythm of training, not the load. On the days in between, walk or cycle and keep the short strength routine going.

By day seven, take stock. Can you walk down stairs normally? Is your resting heart rate back to where it was before the race? Are you sleeping well and waking up with some appetite for training? If the answer to all three is yes, you are ready to build again. If not, give it another few days of the same. Fitness built over months does not vanish in a week.

Signs that deserve more than patience
Soreness after a marathon is spread across both legs, feels dull, and gets better each day. Pain that behaves differently is worth noticing: something sharp, something clearly on one side only, something that gets worse from one day to the next, swelling that does not settle, or anything that changes the way you walk. That is your signal to stop running, keep moving gently, and if it has not calmed down within a week, have someone qualified take a look rather than guessing.

What the following weeks look like
An old coaching rule of thumb gives you one easy day for every mile raced, which puts your next hard effort roughly four weeks away. You do not have to be that strict, but keep the first two weeks easy, bring back one quality session in week three, and hold off on your next race for at least a month.

Your next good race starts with how you treat this week. Rest is not time off from training. It is where the training turns into fitness.
