How do I prevent shin splints when I start running?

Shin splints are often associated with increasing training load too quickly or running on hard surfaces. Gradually building your mileage, wearing well-fitted running shoes, and incorporating calf-strengthening exercises may help reduce the risk.

How many days a week should a beginner run to avoid injury?

Most beginner running programmes suggest starting with two to three runs per week, with rest or active recovery days in between. This allows your muscles, tendons, and bones time to adapt to the new demands being placed on them.

Is it normal to feel sore after running as a beginner?

Mild muscle soreness — often called delayed onset muscle soreness (DOMS) — is common and typically settles within 24 to 48 hours. Sharp, persistent, or worsening pain is different and may be worth discussing with a healthcare professional.

Does stretching before running actually prevent injuries?

Research on stretching and injury prevention is mixed. However, dynamic warm-up movements before running — such as leg swings and hip circles — are generally recommended to prepare the muscles and joints for activity, rather than static stretching before exercise.

What is the 10% rule in running?

The 10% rule is a commonly cited guideline suggesting that beginners increase their weekly running mileage by no more than 10% at a time. While the evidence behind the exact figure is limited, the broader principle of gradual progression is well-supported in sports medicine.

How to Prevent Running Injuries: Beginner's Guide

You lace up your trainers, step outside, and feel that rare burst of motivation to finally make running a habit — only to find yourself sidelined with sore shins two weeks later. Sound familiar? Running injuries are surprisingly common among beginners, but many of them are also largely preventable with a little planning and patience.

Doing too much too soon is one of the most common causes of beginner running injuries.

Conditions like shin splints, runner's knee, and plantar fasciitis are frequently reported by new runners — and may often be avoided with smart training habits.

Warming up, cooling down, wearing appropriate footwear, and gradually increasing mileage are all associated with lower injury risk.

Rest and recovery are not optional extras — they are a core part of any sustainable training plan.

Why Beginners Are Especially Vulnerable to Running Injuries

Running places significant repetitive stress on the muscles, tendons, joints, and bones. When you're new to the sport, your body simply hasn't had time to adapt to that load. Sports medicine research consistently suggests that a mismatch between training load and the body's ability to recover is a primary driver of overuse injuries.

Many beginners also underestimate the cumulative impact of running. Unlike a single hard workout, overuse injuries develop gradually — often without obvious warning signs until the damage is done. This makes prevention far more effective than waiting for pain to appear.

If you're just getting started, you may also find it helpful to read our beginner's guide to starting running, which covers building your first training plan from scratch.

The Most Common Running Injuries in Beginners

Understanding what you're trying to prevent is a useful first step. While every runner is different, some injuries appear far more frequently in those new to the sport.

Shin splints (medial tibial stress syndrome): A dull, aching pain along the inner edge of the shinbone. Often associated with rapidly increasing training volume or running on hard surfaces.
Runner's knee (patellofemoral pain syndrome): Pain around or behind the kneecap, frequently linked to muscle imbalances, overpronation, or doing too much too soon.
Plantar fasciitis: Heel pain caused by irritation of the thick band of tissue running along the bottom of the foot. More common in those with tight calves or poor footwear support.
IT band syndrome: Pain on the outside of the knee, often associated with hip weakness and inadequate warm-up routines.
Achilles tendinopathy: Stiffness or pain in the Achilles tendon, which may be aggravated by sudden increases in running load.

Research suggests that a significant proportion of running injuries are preventable with appropriate training modifications. However, individual anatomy, biomechanics, and fitness history all play a role — what works for one person may not work for another.

The Golden Rule: Avoid Running Too Much Too Soon

If there's one principle that underpins almost all running injury prevention advice, it's this: increase your training load gradually. Running too much too soon overwhelms the musculoskeletal system before it has adapted, and is widely considered a leading cause of beginner injuries by sports medicine professionals.

You may also find knee pain when squatting: causes and form fixes useful.

A commonly used guideline — sometimes called the 10% rule — suggests increasing your weekly running mileage by no more than 10% per week. While the evidence specifically behind this exact percentage is somewhat mixed, the broader principle of gradual progression is well-supported in sports science literature.

It's also worth thinking beyond just distance. Running pace, frequency, terrain type (e.g., switching from grass to pavement), and hill work all add to your overall training load. Try to change only one variable at a time when you're starting out.

Warm-Up, Cool-Down, and Flexibility

Many beginners skip the warm-up in favour of jumping straight into their run. However, warming up prepares the muscles, joints, and cardiovascular system for the demands ahead — and many coaches and physiotherapists recommend it as a key component of injury prevention.

A good pre-run warm-up doesn't need to be long. Five to ten minutes of brisk walking, leg swings, hip circles, and dynamic stretching (moving stretches rather than holding static positions) may help improve mobility and reduce the risk of muscle strains. After your run, a gentle cool-down and some static stretching could support recovery and maintain flexibility over time.

For more detailed guidance on how to structure your warm-up and cool-down effectively, our article on stretching routines for flexibility and mobility is a great starting point.

The Role of Strength Training in Running Injury Prevention

Running is often thought of as a purely cardiovascular activity, but strength training plays an important supporting role in keeping runners injury-free. Research suggests that strengthening the muscles around the hips, glutes, and core may help reduce the risk of common injuries like runner's knee and IT band syndrome by improving running mechanics and reducing excessive strain on joints.

You don't need a gym to get started. Bodyweight exercises like squats, lunges, glute bridges, calf raises, and single-leg balance work can all support your running training at home. Even one or two short strength sessions per week could make a meaningful difference over time — especially for beginners.

If you're not sure where to begin with strength work, our beginner's home strength training guide walks you through a simple, no-equipment routine you can do alongside your running.

Footwear, Surface, and Running Form

The shoes you run in matter — though perhaps not in the way that aggressive marketing might suggest. There is no single "best" running shoe for everyone, but wearing footwear that fits well, matches your foot type, and is appropriate for the surfaces you run on is broadly associated with reduced discomfort and injury risk.

If possible, visiting a specialist running shop for a gait analysis can help you identify whether you overpronate, supinate, or run with a neutral gait — all of which may influence the type of shoe that suits you best. Replacing worn-out shoes is also important, as cushioning degrades over time even if the upper looks fine.

Running surface also plays a role. Softer surfaces like grass or trail paths are generally considered lower-impact than concrete pavements. If you're building your mileage, mixing up surfaces where you can may help reduce cumulative stress on the legs.

As for running form, beginners don't need to overhaul their technique overnight. However, some evidence suggests that avoiding overstriding (landing with your foot far in front of your body) and maintaining a slight forward lean from the ankles could reduce impact forces. A running coach or physiotherapist can offer personalised guidance if you're concerned about your form.

Rest, Recovery, and Listening to Your Body

Rest days are not a sign of weakness — they are a biological necessity. Muscle repair, tendon adaptation, and bone remodelling all happen during recovery, not during the run itself. Many beginners feel guilty about taking rest days, but skipping them consistently is one of the fastest routes to injury.

Most beginner programmes recommend running no more than three to four times per week, with at least one full rest day between sessions. Active recovery — such as walking, gentle cycling, or yoga — on non-running days may help maintain movement without adding excessive load.

Pay attention to how your body feels. Mild muscle soreness after a run is normal and usually settles within a day or two. Sharp or persistent pain, swelling, or discomfort that worsens during a run are signals worth taking seriously. Running through significant pain often makes injuries worse and extends recovery time.

How to Get Started: Practical Tips for Injury-Free Running

Follow a structured beginner plan. Programmes like Couch to 5K are designed with gradual progression in mind, which may help reduce injury risk compared to ad-hoc training.
Increase mileage slowly. As a rough guide, try not to add more than 10% to your weekly distance from one week to the next.
Warm up before every run. Spend at least 5 minutes walking briskly and doing dynamic movements like leg swings and hip openers.
Cool down and stretch after running. Hold gentle static stretches for the calves, quads, hamstrings, and hip flexors for 20-30 seconds each.
Invest in appropriate footwear. Visit a specialist running shop if you can — or at minimum, replace any trainers that are more than 500 miles old or visibly worn.
Add 1-2 strength sessions per week. Focus on glutes, hips, and calves — these muscle groups are closely linked to many common running injuries.
Take rest days seriously. Schedule them into your plan and treat them as part of your training, not a failure to train.
Don't ignore pain. Mild soreness is expected; sharp, persistent, or worsening pain is a reason to rest and, if it continues, to seek professional advice.
Track your training. Using a recovery or flexibility tracker can help you spot patterns — for example, noticing that soreness peaks after certain types of sessions. Our walking for fitness guide can also help if you need a lower-impact way to stay active while building base fitness.
Stay hydrated and sleep well. Both are associated with better recovery and reduced injury risk. Good sleep in particular plays an important role in how the body repairs tissue after exercise.
