The 6 Mistakes That Cause Most Running Injuries
Running injuries are rarely random. Research consistently shows that training errors - not biomechanics alone - are the primary cause. The 6 most common mistakes: (1) increasing weekly mileage by more than 10%, (2) not taking rest days between runs, (3) running in worn-out or ill-fitting shoes, (4) skipping strength training for legs and core, (5) running through pain instead of resting, and (6) poor running form, especially overstriding. Fix these six errors and you prevent the majority of shin splints, runner's knee, IT band syndrome, and plantar fasciitis cases that sideline beginners.
The Most Common Running Injuries
Runner's knee (patellofemoral pain) causes pain around or behind the kneecap, usually from weak glutes, overstriding, or excessive downhill running. Shin splints (medial tibial stress syndrome) cause pain along the inner shin, typically from too-rapid mileage increases or running on hard surfaces. IT band syndrome causes pain on the outside of the knee from weak hip abductors allowing the knee to collapse inward. Plantar fasciitis causes heel pain from excessive load on the foot arch, often worsened by poor footwear or tight calves. Achilles tendinopathy affects the tendon at the back of the ankle from sudden increases in speed work or hill running. A professional Arion Running Analysis can identify the specific biomechanical risk factors in your gait that predispose you to these injuries, allowing targeted prevention rather than generic advice.
Mistake-by-Mistake Fix Guide
Mistake 1: Too Much, Too Soon
- The 10% rule: never increase total weekly running distance by more than 10% from the previous week.
- If you ran 15 km this week, next week's maximum is 16.5 km. This protects tendons and bones which adapt slower than muscles.
- Every 4th week, reduce volume by 20-30% for a recovery week before building again.
Mistake 2: No Rest Days
- Beginners should never run on consecutive days. Your body repairs and strengthens during rest, not during the run.
- 3-4 running days per week with at least one full rest day between runs is optimal for injury prevention.
- Cross-training (swimming, cycling) on non-running days maintains fitness without the impact loading.
Mistake 3: Wrong or Worn-Out Shoes
- Running shoes lose significant cushioning and support after 500-800 km. Track your mileage and replace them accordingly.
- Shoes that are too narrow, too wide, or lack adequate arch support increase injury risk. Visit a running store for a fit check.
- A performance insole like the Shapes HYROX Edition can extend the usable life of shoes and provide consistent arch support that stock insoles lack.
Mistake 4: Skipping Strength Training
- Weak glutes cause hip drop and knee collapse - the root cause of runner's knee and IT band syndrome.
- Two 20-minute strength sessions per week focusing on single-leg exercises: step-ups, single-leg deadlifts, clamshells, and calf raises.
- Core stability (planks, dead bugs, side planks) keeps your pelvis stable during running and prevents lower back pain.
Mistake 5: Running Through Pain
- Stop running if: pain gets worse during the run, pain is sharp or localised to one spot, pain persists for more than 2 days after a run, or you find yourself changing your form to avoid the pain.
- Safe to continue if: mild general soreness that eases within the first 10 minutes of running and does not worsen.
- Two days of rest and the pain resolves completely? You were likely fatigued. Pain persists after rest? See a physiotherapist before running again.
Mistake 6: Poor Running Form
- Overstriding (landing with foot far ahead of your body) increases impact forces by up to 30% per step. Shorter, quicker steps fix this.
- Excessive vertical bounce wastes energy and increases ground reaction forces on your joints.
- Film yourself from the side for 30 seconds and check: Is your foot landing under your hips? Is your posture upright? Are your arms swinging forward and back?
FAQ
What are the most common running injuries?
Runner's knee (pain around the kneecap), shin splints (inner shin pain), IT band syndrome (outside knee pain), plantar fasciitis (heel pain), and Achilles tendinopathy (back of ankle pain). Together, these account for the majority of running injuries in beginners.
How do I prevent knee pain when running?
Strengthen your glutes (single-leg bridges, clamshells, step-ups), avoid overstriding by increasing cadence, do not increase weekly distance by more than 10%, and ensure your shoes have adequate cushioning. If knee pain persists despite these measures, a gait analysis can identify the specific cause.
What causes shin splints and how do I avoid them?
Shin splints are most commonly caused by increasing running volume too quickly, running on hard surfaces, and wearing shoes with inadequate cushioning. Follow the 10% rule, mix surfaces when possible, replace shoes after 500-800 km, and strengthen your calves with heel raises.
How do I know if I should stop running or push through pain?
Stop if pain worsens during the run, is sharp or localised, persists more than 2 days post-run, or causes you to alter your form. Mild general soreness that eases within the first 10 minutes and does not worsen is usually safe to run through.
Does strength training prevent running injuries?
Yes. Research consistently shows that runners who strength train 2-3 times per week have significantly fewer injuries. Focus on single-leg exercises (they expose and correct asymmetries), glute strengthening (prevents knee and hip issues), and core stability (protects the lower back and pelvis).
Can a gait analysis help prevent injuries?
Yes. A sensor-based gait analysis (like the Arion Running Analysis) identifies biomechanical risk factors that video alone cannot detect: ground contact time asymmetry, pronation patterns, force distribution, and cadence imbalances. This allows targeted prevention - fixing the specific issues in your gait rather than applying generic advice.
