How to avoid running injuries must be one of the most written about subjects in sport. The reason – over 90% of runners will experience one or more of these frustrating injuries during their running career, and once they appear they can be incredibly difficult to resolve.
Running injuries like achilles tendinitis, shin splints, runner’s knee, ITB syndrome and plantar fasciitis are all types of overuse or overload injuries which far too commonly experienced by runners. With good running technique, correctly fitting shoes and appropriate training progressions most of these injuries are avoidable.
Sometimes the cause of these type injuries is easy to work out and treat, for example, too much milage too soon or a novice taking up running in their old gym shoes. If these injuries are caught early, most can be resolved, and with some good training and footwear advice the athlete can be back running fairly quickly. However, sometimes establishing the cause can be complex and multi-faceted. They can even occur with very experienced runners as well as totally unexpectedly. This is where advise from an experienced Sports Physiotherapist is important.
Normally, overuse injuries have a gradual onset, and are therefore often ignored for weeks or even months, in the hope they will just go away on their own accord. This differs from an acute trauma like soft tissue injuries. For example, an ankle injury where swelling and pain may be experienced immediately – preventing or limiting any chance of normal running.
Runners are often advised to rest their overuse injury for a few weeks, only to return to running with no improvement. I rarely recommend this approach as it doesn’t address the cause and also allows scar tissue to form around the injured area. Imagine pouring glue onto a healthy tendon – this will prevent normal stretching and movement of the tendon, the same as scar tissue – causing breakdown and degeneration of the tendon fibres. Active recovery is the key like aqua-jogging, cycling or a cross-trainer might be advised by your Physiotherapist.
With a good understanding of injury avoidance and with an appropriate training strategy, most of these injuries are avoidable. Hopefully, the following tips and explanations will help you to keep running – injury free. Most of the tips are a combination of my own experiences and those of my patients combined with recent research.

The correct running shoes are essential to preventing running injuries
How can a running shoe prevent me from getting running injuries? Running in the correct shoe type is key to avoiding injury. Foot types can vary, from neutral, pronated, supinated, flat feet and wide/narrow feet. There is also so much choice of running shoes, it’s no wonder we see so many runners attend our clinics with completely the wrong shoe for their foot type and often the main cause of injury!
The main purpose of a running shoe is to maintain them in their natural bio-mechanical position and protect your feet from injury. What they should not do is alter your natural running mechanics, thus producing muscle or joint imbalances or asymmetries that can lead to injury.
Depending on your running style, the impact forces when your foot makes contact with the ground can vary between 2 and 7 times your body weight with every stride. These forces resonate throughout your body, travelling to your shins, knees and hips. So it’s essential you choose the correct shoe with the right amount of support.
Locate a specialist running shop that has trained staff who can assess your foot mechanics and provide you with the right choice of shoe for your foot type. They normally have a treadmill where your gait can be assessed, and you can also try out new shoes before you buy them (remember your feet can swell during exercise, so take that into account when choosing the size). A Sports Physiotherapist or Sports Podiatrist can also assess your running mechanics and foot type.
We are often asked about orthotics—a shoe insert that alters or controls foot motion and helps prevent running injuries. For runners with excessive pronation, flat arches, leg length or other foot discrepancies – inserts can help. Studies show that an over-the-counter orthotic can be just as effective as a custom-made one, so try those first. If you still have pain, see a Sports Physiotherapist or Podiatrist that specialises in running.
Another couple of tips: first, once you find your ideal running shoe, invest in a second pair half way through the life of the first pair, and wear them in, thereby minimising the structural differences when you change from old to new. Second, never go to a race with a new pair of shoes, especially a different type or style. This is one sure way to pick up injuries!
Know the running style that is best for you
Since Christopher McDougal’s book “Born to Run” first came out in 2009, there has been a lot of debate about barefoot or minimalistic running. Special shoes and “gloves” have been produced by most of the mainstream shoe manufacturers, and many of the world’s greatest runners like Haile Gebrselassie, come from a background of barefoot running, and let’s face it, this is how everyone ran before running shoes came along in the early 1900’s.
The principle behind this style of running is to land the foot closer to the centre of mass (shorter stride length) around the mid-foot, and engage more of the posterior muscles (the gluteal muscles). This reduces the huge “braking forces” seen in heel strikers.
Is this style of running for everyone? My answer is a resounding “no”. For sure, there are many people using this successfully, but for most of us mere mortals, running shoes will be the first and instinctive approach.
The main injury-prevention benefit of reducing your stride length is the reduction of impact forces to the knee and hip. We have nurtured runners with years of runner’s knee problems back to full, pain-free fitness simply by reducing their stride length, but this can take many months, and running more onto your midfoot or forefoot can cause injuries of their own, like shin splints and calf strains.
Deciding whether you should heel strike, or run with a shortened stride – landing on your mid-foot or even fore-foot is a difficult decision to make. My best advice would be if you are currently running free of injuries then don’t rush into trying something different like a shorter stride length thereby risking what is already working. However, if you do decide to venture down the barefoot/minimalistic running route, then take your time in transitioning from one to the other – this will take months rather than weeks. Remember, just making a small change in the way your feet contact the ground can impact other structures further up the kinetic chain. Depending on each individual’s bio-mechanics, these changes can create a positive improvement towards injury prevention just as easily as cause new injuries. So be cautious when making any change to your running style.
Training and improving is about steady progressions
Running experts like Professor Tim Noakes in his book “Lore of Running“, recommend an increase of no more than a 10% in mileage per week so that muscles and joints can adapt to the extra distance. This modest increase generally works well for an experienced and conditioned runner, but probably will be too much for a novice or heavier runner where 3-5% might be safer.
Also worth taking into account is even a superbly fit and seasoned runner going, for example, from a period of steady state running to hill repeats, will need to make this change using careful progressions of both the speed and volume. Intervals produce totally different running mechanics and ground forces, and the runner will need time to get used to both. At our clinics, we regularly see fit “non-running” athletes like cyclists, who decide to take up running or use running as part of their training, only to develop an overuse injury due to too much too soon. So if you’re a pretty active person, but relatively new to running, give yourself 6-8 weeks of running, 2-3 times per week of 20-40 minutes, before embarking on a 10k, half-marathon or marathon training program. This will allow time to adapt to the impact from running.
Minimising running on roads and pavements, especially downhill, helps to reduce the impact forces and risk of injury. Undulating trails (rather than flat running), forest and land-rover tracks provide the least injury-risk running surfaces. A variety of training surfaces and terrain will both provide better all-round development, as well as reduce the risk of injury.
Warm up correctly
Always allow time to warm up effectively. Most of us have busy lives and often turn up for our training run minutes before the planned session – so the chances of having a proper warm up are gone! Ring any bells? This is a sure way to increase your risk of injury, as well as reduce your performance and enjoyment of the run. How to warm up correctly: allow 10-15 minutes to gradually warm up your muscles and body with jogging at 40-50% of your normal pace, intermixed with dynamic (functional) stretching, for example; leg swings, lunge walking and light skipping. Never over-stretch (especially with static stretching) as this can weaken musculo-tendinous structures and increase the risk of injury.
Specific strength training for running will reduce the risk of injuries
Plenty has been written about the hot topic of strength training for running. My personal view is if running is your main sport then focus on developing the key muscle groups which need to be strong in order to maintain correct mechanic and posture whilst running. These will help reduce the risk of injury as well as improve performance.
The key muscles that will benefit from additional strength training are the gluteal muscles, VMO (part of the quadriceps), core and postural muscles. The best functional exercise that engages all these muscles together is overhead lunges. The overhead part helps to keep your spine in correct alignment and engages the core muscles. Single leg squats is also a good alternative exercise. There are plenty of other options, but I find these two are easy to do as well as the most effective.
Core strengthening can make a huge difference in the prevention running injuries or lower back pain. Pilates classes, a Sports Physiotherapist or Personal Trainer are all good options to provide you with the techniques and progressions. Once you understand these you will be able to do the exercises effectively on your own or continue with a Pilates class.
Other muscles like the calf, hamstring, hip flexors, quadriceps muscles and ITB length are all important for running, but with careful running progressions and following an appropriate training programme, in most cases these structures will develop naturally. However, if any of these structures become painful or dysfunctional, this this might be the time to review your training and technique and include other preventative exercises. Your running Coach or Sports Physiotherapist will help you with this.
Exercise variation reduces the risk of running injuries
Runners who only run are more likely to pick up an overuse injury than those who mix running with other sports like cycling, cross-trainer, rowing or gym circuit training classes like HIIT, Boxercise or CrossFit. Pure runners are also renowned for ignoring the early signs of overuse injuries in the hope they will “run it off”. As they don’t have alternative ways to maintain their fitness (whilst offloading the injury) it is hard to resist training thereby further aggravating the injury. Having a varied programme or alternative exercises/sports other than solely running than you can turn to either during injury, active recovery or just as an alternative to running, will greatly reduce the risk of running injuries.
Many people also use running as means to reduce weight, as well as get fit. Running, especially interval training, is one of the most efficient ways of burning calories and losing weight. However, if you are a little on the heavy side, running can be hard on the joints; so, to begin with, build up your distance slowly, perhaps two short runs per week of 20-30 minutes. If you require further weight loss activities, consider low impact training/sports or exercise as described above. Also avoid running on roads/pavements as much as possible.
Put as much time into quality recovery as you do with your training
Runners are inherently bad at recovering effectively. Many will go for a long run of an hour or two long run and recover with five minutes of stretching. Recovery is all about allowing time for your body to adapt and recover from training loads. Without appropriate recovery strategies overload can develop which may eventually lead to injury.
There are many ways to recover from training, and it would take a full article to detail every option. However, I have found active recovery the most effective way to recover from tough sessions, even if it’s not always the most convenient! Light spinning on a bike or aqua-jogging are two great examples
There are not too many non full-time runners who have the time or facilities to carry out a full training session and then spend another 30-40 minutes or so on an exercise bike or in the pool. If you have the time, great, if not, here are a few other options:
Foam rolling – foam rolling the main muscle groups is an effective way to prepare muscles prior to stretching. See this video link on “how to foam roll for running”. Active stretching – dynamic stretches like leg swings, side swings (groin) and lunges etc, are all good to help remove lactate acid residue. Cold/Ice water bath – if you are running from home, make a bath of cold water (add ice if you have any). Research shows that 10 -15 minutes immersed in a bath up to your hips – is a great way to recover, especially from your longer runs. Best to wear neoprene shorts and a T shirt for this! There is also good evidence that contrast bathing (alternating between cold to warm baths) is effective for recovery but might be difficult to organise. Recovery tights/socks – there are a number of manufacturers that have produced compression or recovery tights & socks. Although most professional athletes use either compression socks or tights as part of their recovery and find they reduce muscle soreness, the research suggests little benefit. Massage – making time for a massage during periods heavy training is always worthwhile to help loosen tight muscles and fascia as well as help remove unwanted toxins that can slow up recovery.
Listen to your body
Even the best laid out plans can go wrong. Listening to my body is something I have always tried to adhere to in order to help me stay free of injury. Occasionally, at the start of a training session I am there mentally, but physically my legs are heavy, tired or sore or all three. I know I’ve not had sufficient recovery and rather than push through the pain I will choose swimming, aqua-jogging or cycling as an alternative, or even have an unscheduled day off! I consistently find the following day I have recovered better and end up completing a great session because I allowed the extra time to recover and adapt.
If you carry out a different type of training, or it was particularly hard or long, you may end up with excessive joint or muscle soreness/stiffness. This is where a re-think of your next training schedule or increasing the length of recovery may make a big difference to your performance.
Injuries – figure out the cause
As a Sports Physiotherapist, when I see overuse injuries from any sport, one of the key factors I must establish is what is causing the overuse injury. Is it the shoes, the training, training surfaces, or wear and tear? If you start to develop an injury, think back to what you may have changed. It may be one thing, or a combination of things but more often than not there will be something that is different. Try to adjust this change or go back to what was working and see if that helps. If not, it’s time to get help and seek out a Sports Physiotherapist who is experienced with running injuries.
Finally, if it’s not broken, don’t fix it
Running is a sport where the bio-mechanics are repetitive, in other words, movement is pretty much the same stride after stride, hence the reason overuse injuries are so common. So when you find the right shoes, the right running style and correct training plan and progressions that works for you – stick to it. Avoid getting drawn into concepts that move you away from what has worked well for you so far.
I hope these tips helps you remain injury-free to enjoy your running.
