Top 3 Reasons Runners Get Injured

October 6, 2025

Expert Advice from Weaver Physiotherapy & Sports Injury Clinic, Northwich

Running is one of the most accessible and rewarding forms of exercise — it builds strength, boosts cardiovascular health, reduces stress, and connects us with nature. But while it may look simple, running places unique demands on the body, and even small imbalances can lead to injury over time.


At Weaver Physiotherapy & Sports Injury Clinic in Northwich, Cheshire, we see hundreds of runners each year — from Parkrunners and marathoners to weekend joggers — all dealing with frustrating pain or recurring injuries. The truth is, most running injuries aren’t caused by a single “bad step” or freak accident. They build up gradually due to repeated stress, overload, or insufficient recovery.


In this blog, our physiotherapy experts break down the Top 3 Reasons Runners Get Injured, explain the science behind each one, and share evidence-based strategies to help you stay healthy, strong, and performing at your best.


1️⃣ High Impact Forces – The Hidden Stress of Every Step


Each time your foot strikes the ground during running, your body absorbs forces up to 2.5 to 3 times your body weight. Multiply that by thousands of steps per run, and you start to understand why the repetitive impact can lead to problems in the muscles, tendons, and joints.


What Are Impact Forces?


Impact forces are the shockwaves that travel up through your foot, ankle, knee, and hip every time you land. The body is built to absorb these — your muscles, tendons, and joints act as natural shock absorbers — but if the load exceeds your tissue capacity or recovery is poor, injury risk skyrockets.


Common Injuries Caused by High Impact:

    •    Shin Splints (Medial Tibial Stress Syndrome)

    •    Stress Fractures in the tibia, metatarsals, or hip

    •    Plantar Fasciitis

    •    Knee Pain (Patellofemoral Pain Syndrome)

    •    IT Band Syndrome


Why Do Some Runners Experience Higher Impact Forces?


Several biomechanical and training factors can increase impact load:

    •    Overstriding: Landing the foot too far in front of the body causes a braking effect and increases stress on the joints.

    •    Poor Footwear: Worn-out or unsuitable running shoes reduce shock absorption.

    •    Hard Surfaces: Continuous running on tarmac or concrete can compound repetitive stress.

    •    Weak Lower Limb Muscles: When the calves, glutes, and core aren’t strong enough, they fail to absorb and control landing forces efficiently.


How Physiotherapy Helps


At Weaver Physio, our physiotherapists use video gait analysis to identify how you land, stride, and move while running. By analysing your mechanics in slow motion, we can pinpoint inefficient patterns like overstriding, knee collapse, or asymmetry that increase impact stress.


Treatment focuses on:

    •    Improving running technique and cadence

    •    Strengthening impact-absorbing muscles (glutes, calves, hamstrings)

    •    Footwear advice based on your running style

    •    Progressive loading programmes to build resilience


Reducing impact isn’t about changing your running style overnight — it’s about optimising how your body manages load so you can run further, faster, and pain-free.


2️⃣ High Repetition – Too Much, Too Soon


Running is a repetitive, cyclical motion — and that’s both its beauty and its risk. When you repeat the same motion thousands of times, small mechanical imbalances or training errors can lead to tissue overload and breakdown.


The Cumulative Load Problem


Unlike contact sports, most running injuries are overuse injuries caused by repetitive microtrauma rather than acute trauma. Every stride is a mini stress test. If your tissues (tendons, muscles, joints, bones) don’t have enough time to adapt and repair, they begin to break down faster than they can recover.


Classic Overuse Injuries from High Repetition:

    •    Achilles Tendinopathy

    •    Runner’s Knee (Patellofemoral Pain)

    •    Hamstring Tendinopathy

    •    IT Band Friction Syndrome

    •    Gluteal Tendinopathy


Training Errors That Lead to Overuse:

    •    Sudden Mileage Increases: Jumping from 20km to 40km a week doubles your load without giving tissues time to adapt.

    •    Too Many Hard Runs: Replacing recovery runs with tempo sessions or sprints increases strain on the body.

    •    Lack of Variation: Running the same route, pace, and surface every time limits movement variability and leads to repetitive strain.

    •    Ignoring Early Warning Signs: Mild soreness is a signal. Pushing through pain is a fast track to injury.


How to Build Smart, Sustainable Training

    1.    Follow the 10% Rule: Don’t increase your weekly mileage by more than 10% at a time.

    2.    Prioritise Recovery Days: Rest and cross-training are essential for tissue repair and adaptation.

    3.    Vary Terrain and Intensity: Mixing up your routes, surfaces, and sessions distributes stress across different tissues.

    4.    Include Strength Training: Resistance exercises for glutes, calves, and core improve load tolerance and stability.

    5.    Listen to Your Body: Niggles are messages — address them early with physiotherapy before they become chronic.


At Weaver Physio, we help runners design progressive training plans that balance load, recovery, and adaptation. Our physiotherapists often combine manual therapy, strength and conditioning, and gait re-education to prevent repetitive overload and improve long-term running resilience.


3️⃣ Lack of Tissue Capacity – When Your Body Isn’t Ready for the Load


The third — and arguably most important — reason runners get injured is a lack of tissue capacity. Simply put, your tissues (muscles, tendons, joints, and bones) can only handle a certain amount of load before fatigue, irritation, or injury occurs. If your training exceeds that limit, the tissues fail.


Understanding Tissue Capacity


Tissue capacity refers to the amount of stress or mechanical load your tissues can tolerate before becoming damaged. The stronger and more resilient your tissues are, the greater the capacity to absorb and handle training demands.


When you run regularly without adequate strength, rest, or recovery, your capacity decreases while the load remains high — a mismatch that leads to injury.


Common Signs of Low Tissue Capacity

    •    Persistent muscle tightness or soreness

    •    Pain that worsens with activity but eases with rest

    •    Declining performance or early fatigue

    •    Recurrent “niggles” that never fully resolve


Injuries Linked to Low Tissue Capacity

    •    Achilles Tendinopathy

    •    Patellar Tendinopathy

    •    Plantar Fasciitis

    •    Hamstring or Calf Strains

    •    Hip or Gluteal Tendon Pain


Why Tissue Capacity Matters


Running doesn’t just test your cardiovascular system — it’s a repetitive strength endurance activity. Each stride is a load challenge to your muscles and tendons. Without regular conditioning, they simply aren’t equipped to meet the demands of consistent training.


Think of it like this:


Load > Capacity = Injury


Load < Capacity = Adaptation and Performance


Your goal as a runner should be to increase capacity — not just run more, but train smarter.


How Physiotherapy Builds Tissue Capacity


At Weaver Physiotherapy & Sports Injury Clinic, we take a scientific approach to rebuilding and increasing tissue capacity. This includes:

    •    Strength & Conditioning Programmes: Progressive resistance exercises to build tendon and muscle strength.

    •    Isometric Loading: Early-stage tendon rehab exercises to reduce pain and build tolerance.

    •    Plyometric & Functional Drills: To develop power and elasticity in the running muscles.

    •    Shockwave Therapy: Stimulates healing and tissue regeneration in chronic tendon problems.

    •    Individualised Rehabilitation Plans: Designed specifically for your goals, running history, and biomechanics.


Our Runner’s MOT and Video Gait Analysis services provide detailed biomechanical insight into how your body moves and where your weaknesses lie — allowing us to target the root causes, not just the symptoms.


How Physiotherapy Prevents Running Injuries


The key to staying injury-free isn’t just reacting to pain — it’s preventing it before it starts. Physiotherapy bridges the gap between training and performance by helping runners:

    •    Identify early signs of overload

    •    Improve movement efficiency

    •    Correct strength and mobility imbalances

    •    Optimise recovery and load management


Preventive Physio Strategies for Runners

    1.    Regular Screening & Gait Assessment – Detect biomechanical faults early.

    2.    Strength Training Twice Weekly – Essential for tendon and joint health.

    3.    Mobility & Activation Drills – Maintain healthy range and muscle balance.

    4.    Gradual Training Progression – Avoid spikes in volume or intensity.

    5.    Recovery Strategies – Massage, sleep, and nutrition to support tissue repair.


At Weaver Physio, our multidisciplinary team includes experts in running biomechanics, sports rehabilitation, and performance conditioning. We use a combination of manual therapy, acupuncture, shockwave, and exercise prescription to help runners across Northwich, Knutsford, Middlewich, Winsford, and Cheshire move better, recover faster, and perform stronger.


When to Seek Physiotherapy for a Running Injury


Don’t wait until pain stops you from running. Early physiotherapy intervention can prevent a small issue from becoming a long-term problem.


You should book an appointment if you:

    •    Experience pain lasting more than 3-5 days

    •    Notice pain during or after every run

    •    Feel numbness, tingling, or shooting pain in the leg or foot

    •    Struggle to increase mileage without soreness

    •    Have recurrent injuries or a persistent niggle in the same area


Our physiotherapists will conduct a comprehensive assessment to determine the cause, not just the site, of your pain. Treatment focuses on:

    •    Relieving pain quickly

    •    Correcting biomechanical faults

    •    Re-educating movement patterns

    •    Rebuilding tissue strength

    •    Preventing re-injury

A Practical Guide for Endurance Runners
October 7, 2026
Have you ever been told that your running style is “wrong” and immediately wondered whether you need to change it? Advice online can make normal differences in movement look like faults. While certain running habits may be worth exploring—particularly when pain keeps returning—there is no single perfect stride, cadence or foot strike for every runner. At Weaver Physiotherapy & Sports Injury Clinic, we take an individual approach to running technique. Your training history, symptoms, strength, mobility, goals and the way you respond to load all matter. For runners in Northwich, Middlewich, Winsford, Knutsford, Sandbach, Frodsham and Tarporley, our Runner’s MOT and running gait analysis⁠ provides clear, personalised feedback rather than generic rules. What are common running form mistakes? A “running form mistake” is often better described as a movement habit to investigate. A pattern may look unusual without being harmful, and a video alone cannot confirm that it is the cause of pain. Common concerns include: Overstriding – the foot appearing to land well ahead of the body. Upper-body tension – raised shoulders, clenched hands, a tight jaw or stiff arm swing. Forcing foot strike – deliberately trying to run on the forefoot or heel when it feels awkward. Slumped posture – losing trunk control as fatigue develops. Abrupt changes in technique – trying to alter cadence, posture and foot strike at the same time. These patterns can change with pace, hills, footwear, fatigue, confidence and training load. Research has found limited evidence that individual biomechanics alone predict running injury, which is why form should be considered alongside the wider picture rather than treated as a diagnosis. Is there one correct way to run? No. Effective running does not look identical from person to person. Your anatomy, strength, experience, speed, terrain and fatigue level all influence your stride. A single photograph or short clip captures only one moment. It cannot explain how you feel during a run, what your training has involved that week, or whether a movement pattern is actually contributing to symptoms. If you are comfortable, progressing well and free from persistent pain, you may not need to change your technique simply because it differs from someone else’s. The aim is not to chase a “perfect” running style. It is to understand your own movement and make sensible adjustments only when they are relevant to your goals or symptoms. How to assess your running form safely Start with one question. Perhaps your foot feels as though it reaches too far forwards, your shoulders tighten on longer runs, or you notice discomfort appearing as you fatigue. During an easy run at your usual pace, consider: Does your breathing feel relaxed? Are your shoulders, hands and jaw unnecessarily tense? Does your stride feel comfortable and natural? Does your movement alter later in the run? Is there recurring pain during, after or the following day? If you use video, record a brief clip from a safe, consistent position beside the route or on a treadmill. Never hold or watch a phone while running. Footage can be useful for observation, but it should prompt questions—not provide a self-diagnosis. How to change running technique without overdoing it Avoid making dramatic changes based on a social-media tip or a one-size-fits-all rule. A sudden change in cadence, posture or foot strike may feel unnatural and can make it difficult to work out what is helping. Instead: Choose one area to explore. Use one simple cue during an easy run. Keep the adjustment gentle and brief. Notice how it feels during the run and over the next 24–48 hours. Do not introduce several technique changes at once. For example, if you feel tense through the upper body, a helpful cue may be “soft shoulders and easy arms” rather than forcing a rigid posture. If you are concerned about stride length, focus on a light, comfortable rhythm rather than trying to land in a prescribed position. Training progression matters too. Increasing distance, pace, hills and frequency too quickly can overload tissues, regardless of how your running looks. NHS advice recommends building running gradually and listening to pain rather than pushing through it. Read the NHS guide to common running injuries ⁠. When should you seek individual running advice? Consider a running assessment if pain: Keeps returning or becomes more severe Changes the way you run Persists after reducing or adapting training Is associated with swelling, weakness, limping or a loss of confidence Leaves you unsure which changes, if any, are appropriate Sudden severe pain, inability to bear weight, major swelling, numbness, deformity or a suspected serious injury should be assessed urgently. NHS guidance on sprains and strains explains when to seek urgent help. What can running gait analysis help with? A running gait analysis does not promise to predict injury or reveal one universal correction. It can, however, provide a clearer view of movement patterns in the context of your symptoms, training and goals. At Weaver Physio, our Runner’s MOT (/runners-mot)⁠ combines slow-motion video gait analysis with strength, mobility and movement assessment. We look at factors such as: Running rhythm and lower-limb control Trunk, hip, knee and foot movement Strength, balance and mobility Previous injuries and current symptoms Training volume, recovery and running goals Your findings are then used to create practical, personalised recommendations. This may include a gradual gait cue, running-specific strength work, mobility exercises, load-management advice or a structured return-to-running plan. Our Chartered Physiotherapists and Sports Rehabilitators bring more than 70 years of combined clinical experience to help runners move with greater understanding and confidence. Build a stronger, more confident running stride Running form is not a test you have to pass. A movement pattern may be worth exploring, but it does not automatically mean that something is wrong. Pay attention to comfort, recurring symptoms and changes that develop with fatigue. Make adjustments gradually, progress training sensibly and seek individual support if pain continues. For runners across Northwich and Cheshire, Weaver Physio’s running gait analysis service (/runners-mot)⁠ offers professional, tailored guidance to help you run stronger and with more confidence. Frequently Asked Questions Is there one correct running form for everyone? No. There is no single ideal foot strike, cadence or posture that applies to every runner. Comfortable, efficient running can look different depending on the individual, their pace, experience and physical characteristics. Can changing my running form cause pain? It can. Sudden or uncomfortable changes may increase stress in unfamiliar areas. Make one gradual change at a time and reduce or stop if pain worsens. How can I tell if I overstride? Overstriding may appear as the foot landing well ahead of your body, but this does not automatically mean it is causing a problem. A short video can provide useful context, while a gait assessment can help interpret the pattern alongside your symptoms and training. When should I book a running gait analysis? Book an assessment if pain is recurring, your running style has changed, you are returning from injury, or you would like clearer guidance about your stride and training.

Expert Joint Care
September 21, 2026
Persistent pain at the back of the heel can make simple things—walking the dog, climbing stairs, training for the Knutsford 10K or enjoying a run around Tatton Park—feel far more difficult than they should. At Weaver Physiotherapy & Sports Injury Clinic, we provide shockwave therapy ⁠ as part of a structured rehabilitation programme for people with persistent Achilles tendon pain. Our Northwich clinic is easily accessible from Knutsford and supports active adults, runners and sportspeople across Cheshire. The goal is not simply to settle symptoms for a few days. It is to understand why the tendon is painful, improve its capacity for load, and help you return to the activities that matter to you with greater confidence. Achilles Tendinitis or Achilles Tendinopathy? “Achilles tendonitis” is the term most people use when describing pain, stiffness or swelling around the tendon at the back of the ankle. However, when symptoms have persisted for several weeks or months, the more accurate clinical term is often Achilles tendinopathy. Tendinopathy is a complex condition associated with tendon pain, reduced function and lower tolerance to exercise or repeated loading. The tendon may become more sensitive and less able to cope with the demands being placed upon it. It is not always a straightforward inflammatory problem, which is why complete rest, stretching or massage alone may not create a lasting solution. A detailed review of tendinopathy research describes the changes that can occur within painful tendons and the importance of an individualised management approach. Common symptoms include: Pain or stiffness at the back of the heel, especially first thing in the morning Discomfort when walking uphill, climbing stairs or rising onto tiptoes Pain during or after running, football, tennis, gym training or long walks Thickening or tenderness in the tendon Symptoms that improve as you warm up, then return later At Weaver Physio, we assess whether your symptoms are likely to be related to mid-portion or insertional Achilles tendinopathy, and screen for other possible causes of heel and calf pain. If there is concern about a rupture, significant tear or another condition requiring medical investigation, we will advise on the appropriate next step. What Is Shockwave Therapy? Extracorporeal Shockwave Therapy—often shortened to ESWT or radial shockwave therapy—uses controlled acoustic pressure waves delivered through a handheld applicator. It is not an electric shock and does not involve injections or surgery. During treatment, gel is applied to the skin and the handpiece is positioned over the relevant area of the Achilles tendon. The sensation is commonly described as firm tapping or pulsing. Your clinician can adjust the treatment intensity to keep it manageable. Shockwave therapy may be considered for longer-standing tendon pain, particularly where a well-planned rehabilitation programme has not yet delivered the progress you need. It should always be used following a thorough assessment and alongside progressive exercise—not as a standalone “quick fix”. How Shockwave Therapy May Help Achilles Pain Shockwave therapy is thought to influence pain sensitivity and stimulate biological responses within the tendon and surrounding tissues. The practical aim is to create a window in which you can move more comfortably and build strength more effectively. For Achilles tendinopathy, a comprehensive treatment plan may help you to: Reduce pain that is limiting walking, work or sport Improve confidence with daily activity and exercise Progress calf-strength and tendon-loading exercises more successfully Address training errors, footwear issues and movement factors contributing to overload Build resilience for a return to running, sport or long-distance walking Outcomes vary between individuals. Some people notice a change in symptoms early in treatment, while tendon adaptation and improvements in load tolerance typically take longer. We will always discuss realistic expectations and measure your progress against your own goals. Your Shockwave Therapy Assessment Near Knutsford Your journey starts with a detailed physiotherapy assessment. We look beyond the painful spot to understand the full picture, including: Your symptom history and training or activity levels Previous injuries and treatment Calf strength, ankle mobility and balance Achilles tendon tenderness and loading tolerance Footwear, running surface and recent changes in training volume Hip, knee and foot control where relevant This allows us to confirm whether shockwave therapy is an appropriate option and develop a recovery plan tailored to you. Weaver Physio’s team also provides specialist physiotherapy and sports injury rehabilitation ⁠, so your treatment can be integrated with hands-on care, exercise rehabilitation and return-to-sport planning where needed. What Does a Typical Course Involve? A course of shockwave therapy commonly involves three to five sessions, often spaced about one week apart. The exact number and timing will depend on your presentation, response to treatment and rehabilitation goals. Each appointment is combined with guidance on tendon loading. This may include: Isometric calf exercises for pain management Progressive heel raises and heavy slow resistance work Soleus and gastrocnemius strengthening Balance, control and single-leg stability work A gradual return to running, hills, speed work or plyometric exercise Rather than avoiding all activity, we help you find an appropriate level of movement that keeps the tendon challenged without repeatedly exceeding its current capacity. Is Shockwave Therapy Right for You? Shockwave therapy may be suitable if you have persistent Achilles symptoms that have not settled with sensible activity modification and a targeted rehabilitation programme. It is particularly relevant for people who want a non-invasive option before considering more invasive interventions. However, it is not suitable for everyone. Your physiotherapist will discuss relevant precautions and assess factors such as pregnancy, blood-clotting issues, certain medications, recent steroid injection near the treatment area, suspected rupture or other medical considerations. It is also important to seek urgent medical advice if you experience a sudden pop in the back of the ankle, immediate weakness when pushing off, marked bruising or an inability to rise onto your toes. These can be warning signs of an Achilles rupture. Why Choose Weaver Physio? Weaver Physiotherapy & Sports Injury Clinic combines clinical assessment with a practical understanding of sport, training and everyday activity. We are based in Northwich and regularly support patients travelling from Knutsford, Alderley Edge, Holmes Chapel, Middlewich and across Cheshire. Our approach is built around three principles: Accurate assessment We identify the likely driver of your Achilles pain rather than treating every heel problem the same way. Evidence-informed rehabilitation Shockwave therapy is used as one part of a clear, progressive plan designed to restore strength and confidence. A return to the life you enjoy Whether your goal is pain-free dog walks, a hiking holiday, club running or competitive sport, your programme is shaped around it. Book an Achilles Tendon Assessment Persistent Achilles pain does not have to dictate how active you can be. If you are looking for shockwave therapy for Achilles tendinitis in Knutsford, Weaver Physio can help you understand your options and build a tailored recovery plan. Contact Weaver Physiotherapy & Sports Injury Clinic to arrange an assessment: Book or contact Weaver Physio 01606 227 484 07795 908 027 110 Middlewich Road, Northwich, CW9 7DP Frequently Asked Questions Is shockwave therapy painful? Most people describe shockwave therapy as uncomfortable rather than painful. The feeling is similar to firm tapping against the skin, and the intensity can be adjusted throughout treatment. Mild soreness, redness or tenderness can occur afterwards and usually settles within a few days. How many sessions will I need? Many patients have a course of three to five sessions, usually one week apart. Your clinician will recommend an appropriate plan based on your symptoms, tendon presentation and response to treatment. Can I exercise after shockwave therapy? Light daily activity is usually encouraged, but your clinician may advise avoiding high-impact exercise—such as running, jumping or hard hill work—for a short period after treatment. You will be given clear guidance on what to continue, reduce and progress. Will shockwave therapy cure my Achilles pain? No treatment can guarantee a cure. Shockwave therapy may help reduce pain and support recovery in suitable cases, but lasting improvement usually depends on combining treatment with a progressive loading programme, sensible activity management and a gradual return to sport.
