Common Running Injuries and Why They Happen

Most running injuries don't come from a single bad step. They build quietly over weeks of accumulated load, then announce themselves all at once. At Marlow Movement Clinic, we see the same handful of presentations again and again, and almost all of them trace back to training errors rather than bad luck.

Running injuries are musculoskeletal complaints caused by repetitive stress on bone, tendon, muscle or fascia, most often in the lower limb. The common ones are:

• Medial tibial stress syndrome (shin pain along the inner tibia)
• Achilles tendinopathy (pain and stiffness in the heel cord)
• Plantar heel pain (sharp pain under the heel, worst on first steps)
• Patellofemoral pain (aching around the kneecap, worse on hills or stairs)
• Iliotibial band related pain (outer knee pain)
• Stress fractures (localised bone pain, often the shin or foot)

The mechanism is almost always the same: tissue capacity falls behind training demand. A common mistake is adding distance, speed and hill work in the same week. Each one increases load, and stacked together they outpace what tendons and bone can adapt to.

Strength Training for Runners: Building a Resilient Body

Strength work is the most reliable injury prevention tool a runner has, and it's the one most runners skip. Two sessions a week of heavy-enough resistance training improves tendon stiffness, bone density and running economy. The key word is heavy: bodyweight circuits feel productive but rarely load tissue enough to drive adaptation.

Key Exercises for Runners

• Single-leg squat, 3 sets of 6-8 per leg, builds knee and hip control
• Heavy calf raise (standing and seated), 4 sets of 6, loads the Achilles and plantar fascia
• Romanian deadlift, 3 sets of 8, targets hamstrings and glutes
• Split squat, 3 sets of 8 per leg, addresses single-leg strength deficits
• Hip abduction with band, 3 sets of 12, supports pelvic stability

Start with two sessions per week on easy running days, and progress the weight before the volume. Expect the first three to four weeks to feel manageable; that's the point.

Running Training Load Management: The 10% Rule and Beyond

The 10% rule is a useful starting point, not a law. It suggests increasing weekly distance by no more than 10% week on week. In practice, load management is about three variables moving together: volume, intensity and surface.

A stronger approach tracks your acute-to-chronic workload ratio, this week's training compared with your four-week average. A common approach is to keep the acute week within roughly 0.8 to 1.3 times your chronic average. Go above that and injury risk climbs.

NHS guidance on exercise and injury prevention supports gradual progression rather than sudden spikes in activity. The principle applies whether you're returning from a break or building towards a race.

Signs of Overtraining in Runners: When to Back Off

Overtraining shows up before injury does, if you know what to look for. The earliest signs are usually non-musculoskeletal: disturbed sleep, a resting heart rate that sits a few beats higher than normal, irritability, and a loss of motivation for sessions you normally enjoy.

Physical warning signs include:

• Persistent soreness that doesn't ease within 48 hours
• Niggles that move around rather than settling
• Reduced pace at the same effort
• Appetite changes or frequent minor illness

If two or more of these appear together, cut volume by around a third for a week and drop intensity sessions entirely. Most runners find that a planned easy week prevents the unplanned one that follows an injury.

Recovery Strategies for Runners That Actually Work

Recovery is where adaptation happens, and most runners treat it as an afterthought. The strategies with the strongest evidence are unglamorous: sleep, adequate protein, and genuinely easy easy days.

Sleep is the single biggest lever. Aim for seven to nine hours, and treat a consistent bedtime as part of training. Protein intake of roughly 1.6g per kilogram of bodyweight per day supports tissue repair. Easy days must be genuinely easy, conversational pace, not "comfortably hard".

What matters less than the internet suggests: ice baths, compression boots and most recovery gadgets. They may help you feel better, but they don't substitute for sleep and load management.

Footwear and Running Form: What Matters for Injury Prevention

Footwear matters, but not in the way most marketing suggests. There is no single "best" shoe, and gait retraining is not a universal fix. The right shoe is the one that fits your foot, suits your terrain, and doesn't cause you to alter your natural stride.

Practical guidance:

• Replace shoes based on midsole wear, not a fixed mileage number
• Rotate between two pairs to vary loading patterns
• Avoid sudden switches to minimal shoes; transition over months, not weeks
• Choose comfort over category, "stability" and "neutral" labels matter less than fit

Form changes are worth considering only when there's a specific problem to solve. Increasing cadence slightly, by around 5%, often reduces load on the knee and hip. Beyond that, most runners are better served by strength work than by trying to overhaul their stride.

When to Seek Professional Help for Running Injuries

See a qualified professional if pain persists beyond two weeks, worsens despite reduced training, or is sharp and localised to a small area of bone. Night pain, swelling that doesn't settle, or an inability to weight-bear normally all warrant prompt assessment.

A physiotherapist or musculoskeletal specialist can assess loading, strength and movement patterns, then build a plan that progresses you back to running rather than just resting. At Marlow Movement Clinic, we combine hands-on treatment with a practical rehabilitation plan you can follow between sessions, and we offer free 15-minute phone consultations if you're unsure whether you need to be seen. Mark Skoyles (BSc Hons), our Clinical Lead, has been in practice since 1996 and specialises in musculoskeletal injuries of the spine, upper and lower limbs.

You don't need a GP referral to book directly with a physiotherapist. If you're unsure, NHS information on when to seek help for joint and muscle pain is a useful starting point.

Running injuries rarely come from one bad run. They come from load that outpaces what your body has adapted to, and they're prevented by the same unglamorous basics: sensible progression, strength work twice a week, real recovery, and shoes that fit. If pain has been lingering or you're unsure how to get back to running safely, Marlow Movement Clinic can help. Book online for a hands-on assessment and a clear, actionable plan you can follow between sessions, with same-day appointments often available.
