Running injuries on the Costa del Sol: how to return safely

Why you''re getting injured when you return to running — and how to prevent it

Spring is here, the days are longer, and suddenly everyone is lacing up their trainers again. This is also the time of year I see a surge of new clients in the clinic, all dealing with the same thing: injuries that didn''t have to happen. Whether it''s a grumbling Achilles, achy knees, or shin pain that won''t quit, most spring running injuries share one root cause — doing too much, too soon, after doing too little for too long. With a bit of awareness and a few simple strategies, they''re almost entirely preventable.

At Physio Flora, with clinics in Marbella and Riviera del Sol, we treat runners across the Costa del Sol every week — from expats returning to the coastal paths after a winter break to competitive club runners preparing for autumn races. In this guide you''ll find why returning runners get injured, the most common spring running injuries we see, how to return to running without getting hurt, and answers to the questions our patients ask most.

The problem: your body forgot what running feels like

Running is a high-impact sport. Even at a comfortable pace, each foot strike sends a force equivalent to roughly two to three times your body weight through your joints and tissues. Your tendons, bones, and muscles adapt to handle this load — but only if you give them consistent exposure to it.

During winter, most people''s running volume drops significantly. Some stop altogether. That is completely fine. But when spring arrives and the motivation spikes, the temptation is to jump straight back to the mileage and intensity you were managing in autumn. Your cardiovascular fitness may recover relatively quickly — but your tendons, ligaments, and bones need significantly longer, often weeks to months, to rebuild their load tolerance.

This mismatch between what your heart and lungs can handle and what your tissues can handle is where injuries are born.

The most common spring running injuries we see

The Costa del Sol is one of the best places in Europe to run — year-round sunshine, coastal paths, and hillside trails. It is also a region where running injuries spike sharply every spring. These are the four we treat most often in returning runners:

• Shin splints (medial tibial stress syndrome) — a dull ache along the inner edge of the shinbone during or after a run. It often feels fine when you warm up, only to return worse the next morning. Bone responds to load more slowly than muscle: when running volume increases faster than your tibia can adapt, the bone''s outer layer (periosteum) becomes inflamed.
• Achilles tendinopathy — a stiff, achy Achilles, especially that first step out of bed in the morning, is a classic sign of tendon overload. The Achilles is remarkably strong but notoriously slow to heal once irritated. Tendons thrive on gradual, progressive loading; a sudden spike in mileage or intensity — including adding hills or speed work too early — is the most common trigger.
• Runner''s knee (patellofemoral pain syndrome) — that vague ache around or behind the kneecap, often worse when going downstairs or after sitting for long periods. Prolonged sitting leads to weakened glutes and tight hip flexors, which alter how the kneecap tracks in its groove. Add running load on top and the joint surface becomes irritated.
• Plantar fasciitis — a sharp, stabbing pain under the heel, particularly excruciating on the first step in the morning. The plantar fascia (the thick band of tissue supporting the arch) loses its load tolerance after a period of inactivity, and a sudden return to impact overstresses it before it has time to adapt.

Structured, progressive training — not motivation alone — is what protects returning runners from injury.

The 10% rule, and why it''s not quite enough

You have probably heard of the 10% rule: don''t increase your weekly mileage by more than 10% per week. It is a reasonable starting point, but it is not the whole picture.

The 10% rule addresses volume, but it does not account for:

• Intensity — adding speed sessions on top of more miles is a double load spike.
• Your starting point — 10% of zero is still zero; returning runners need an absolute floor.
• Recovery capacity — stress, poor sleep, and nutrition all affect how well your body adapts.
• Terrain — going from flat pavements to hilly trails counts as an intensity jump.

A more useful framework is managing your acute-to-chronic workload ratio — the idea that your body handles load well when this week''s training isn''t dramatically higher than your average over the past four weeks. If you''ve been doing very little, your chronic load is low, which means your safe acute ceiling is also low, even if it feels easy in the moment.

How to return to running without getting hurt

• Start slower than you think you need to. The most common mistake is letting your fitness level dictate your starting volume when it should be your tissue tolerance. If you have had a break of more than four to six weeks, treat yourself as a relative beginner again, regardless of your previous fitness. A run-walk approach is genuinely excellent and allows your body to accumulate training stimulus while managing tissue load.
• Prioritise strength work. Runners are often reluctant to spend time not running, but strength training is one of the most powerful injury-prevention tools available. Strong glutes, calves, and hip stabilisers reduce the mechanical stress on your knees, Achilles, and feet with every stride. Two sessions a week of targeted lower-limb strength work — single-leg calf raises, Romanian deadlifts, hip thrusts, and lateral band walks — can make a significant difference. Thirty minutes is enough.
• Don''t skip the warm-up. A proper warm-up is not just about preventing muscle strains; it primes your neuromuscular system for the demands of running. Five to ten minutes of dynamic movement (leg swings, hip circles, walking lunges, light jogging) prepares your tissues to absorb load more effectively. Static stretching before a run has limited evidence behind it — save the deep stretching for after.
• Listen to your body, and know the difference. There is a difference between the discomfort of exertion (normal) and the discomfort of tissue strain (a signal to stop). Discomfort that eases as you warm up and doesn''t persist after your run is usually fine. Pain that gets worse during the run, or is still there the next morning, means reduce load and seek assessment if it persists more than a week or two. Sharp or sudden pain: stop immediately.
• Get your footwear sorted. Running shoes have a lifespan of roughly 500–800 km, after which the midsole cushioning degrades significantly even if the upper looks fine. If your shoes have been sitting in a cupboard for six months, they may be well past their best. It is worth getting a proper gait assessment at a specialist running store before ramping up your training.

Steps, hills, and uneven terrain all count as intensity — reintroduce them gradually, not on your first week back.

When to see a physiotherapist

Not every ache needs professional input, but there are times when it is worth getting eyes on:

• Pain that persists for more than two weeks despite reducing your load
• Swelling around a joint or tendon
• Pain that stops you from completing a run
• Any sudden, sharp, or severe pain
• Symptoms that keep coming back every time you try to return to running

Early intervention almost always means faster recovery. Tendons and stress fractures in particular respond much better to treatment when caught early — waiting to "run through it" often means a much longer time off down the line.

How physiotherapy helps returning runners

At Physio Flora, treatment for running injuries is never generic. Each rehabilitation plan is tailored to the diagnosis, the stage of healing, and the runner''s goals — whether that is being able to jog along the Paseo Marítimo pain-free or preparing for a half marathon in the autumn.

• Accurate clinical diagnosis — we identify the exact structure involved (bone, tendon, joint, or fascia), the severity, and any biomechanical or training-load factors that contributed. This is where DIY recovery most often falls short: treating the symptom rather than the cause.
• Manual therapy and soft-tissue techniques — reduce pain, control local inflammation, and restore normal joint and muscle mechanics in the early stages.
• Progressive loading and strength rehabilitation — the heart of tendon and bone recovery. A structured programme gradually reloads the injured tissue through its full range, rebuilding strength, power, and load tolerance.
• Dry needling and shockwave therapy — highly effective for chronic tendinopathy, plantar fasciitis, and stubborn calf or hamstring tension.
• Running gait analysis and retraining — for recurring injuries, changes in cadence, stride length, and foot strike often unlock progress that pure strength work cannot.
• Return-to-running plan — "pain-free" is not the same as "ready to train." We use functional benchmarks and a phased plan to determine when it is genuinely safe to increase load, and by how much.

Frequently asked questions

How long should I wait before running again after an injury?

It depends entirely on the injury, its severity, and how it responds to early treatment. Mild soft-tissue overload may only need 5–10 days of modified activity; a tendinopathy or stress reaction typically needs several weeks of structured loading before running is reintroduced. The safest — and usually the fastest — route is an early physiotherapy assessment, so the plan is based on your tissue, not guesswork.

Is it normal to feel pain the day after running?

Some general muscle soreness after a hard session is normal, particularly when you are building volume. Pain that is sharp, localised to a joint or tendon, or that persists into a second or third day is not normal — it is a signal that a tissue is not tolerating the load and should be assessed if it does not settle with a few easier days.

Do I need running shoes with more cushioning to prevent injury?

Not necessarily. Research does not consistently support the idea that "more cushioning = fewer injuries." What matters far more is that your shoes suit your foot mechanics, are within their functional lifespan (typically 500–800 km), and are appropriate for the terrain you run on. A gait assessment at a specialist running store is a much better investment than simply buying the most cushioned model on the shelf.

Can physiotherapy help even if I''ve had the same injury multiple times?

Yes — and if it is recurring, that is exactly when physiotherapy adds the most value. Recurrent injuries almost always point to an unresolved underlying factor: a strength deficit, a movement pattern, a training-load pattern, or a footwear issue. Identifying and addressing that factor is the difference between another temporary fix and a long-term solution.

Is there an English-speaking sports physiotherapist near Marbella or Fuengirola for running injuries?

Yes. Physio Flora is based in Riviera del Sol, conveniently located between Fuengirola and Marbella. All consultations are conducted in English, and we work regularly with runners across the international community on the Costa del Sol — from casual joggers to competitive club and marathon runners.

Should I keep running through mild pain, or stop completely?

Neither extreme is usually right. Complete rest is rarely optimal — most running injuries recover faster with modified, progressive loading than with full rest. But running through pain that gets worse during or after the session almost always makes the problem worse. The correct middle path — how much to reduce, what to substitute, when to progress — is what a physiotherapy assessment gives you.

The bottom line: return to running should feel good

Returning to running in spring should feel good. It can feel good — the physical benefits, the mental lift, the satisfaction of covering ground under your own power. But your body is a biological system that responds to load gradually, and it does not care how motivated you feel.

Give your tissues the time they need to adapt, build strength alongside your mileage, and you will be running consistently through summer and beyond — instead of spending it recovering from an injury that did not have to happen.

At Physio Flora we combine thorough clinical assessment with evidence-based, athlete-centred rehabilitation and a genuine understanding of the active, outdoor lifestyle of the Costa del Sol. We see runners from Riviera del Sol, Marbella, Fuengirola, Estepona, Benalmádena, Mijas Pueblo, and across the region.

No referral needed. English-language consultations. Same-week appointments for acute injuries.
