Every spring, and after every quieter winter, physiotherapy clinics see the same pattern. People who have run for years suddenly develop calf pain, Achilles issues, or shin soreness within a few weeks of picking things back up. It tends to happen to experienced runners as much as beginners. The issue almost never comes down to bad luck.
The most common reason people get injured when returning to running is that the body has changed during the break, but the training does not account for that. You may have maintained a reasonable level of general fitness, but your tendons, muscles, and connective tissue have adapted to lower loads. Trying to restart where you left off creates a gap between what your body is being asked to do and what it can currently tolerate.
That gap is what causes injury. Not weak ankles. Not old trainers. Not running form, in most cases. Load.
The good news is that this is almost entirely manageable. Understanding where the mistakes happen is the first step.
How do I get back into running after a break?
Start with less volume than you think you need and build from there. Begin with short, easy runs three times a week, leaving at least one rest day between sessions. Avoid jumping back to your previous pace or distance in the first few weeks. Consistent, manageable training tends to produce better results than doing too much in week one.
After a winter of reduced training or a break of any length, the temptation is to test what you can still do. That is understandable. But your cardiovascular system tends to recover faster than your musculoskeletal system. You may feel capable of running your usual distance. Your calf tendons and tibial stress response may disagree.
A sensible return to running looks something like this: short runs in the first week or two, easy enough that you could hold a conversation throughout. Three runs a week with a rest day between each. No hills, no speed work, no back-to-back days. Build from that base rather than treating week one as a comeback statement.
Consistency across several weeks matters far more than what you achieve on day one.
Why do people get injured when they start running again?
Tissue tolerance is the key concept here. When you run regularly, your tendons, muscles, fascia, and bones adapt to the repeated stress of impact. Take a break, and those tissues gradually lose some of that capacity. It happens even over a few weeks. After a full winter of reduced activity, the adaptation loss is more significant.
This is not the same as becoming unfit. Someone who has been going to the gym through winter may have good aerobic capacity and reasonable lower limb strength. But gym-based fitness does not replicate the specific demands of running, and tendons in particular respond slowly to changes in load.
Consider a runner who was regularly covering 10 kilometres before Christmas. By February, they have done very little running. They go out for a 7k run on a crisp morning, feel fine, and then do the same three days later. By week three, they have Achilles soreness. Nothing dramatic happened. The problem was cumulative load on a structure that had not been adequately prepared.
The spring weather compounds this. Longer days and better conditions tend to push people to run more frequently and add distance quickly. Hills appear. A friend suggests a faster pace. The load spikes, and the injury follows.
A physiotherapist who works with runners can help you identify whether your current training load is appropriate for where your body actually is, rather than where it was six months ago. You can read more about running injuries we commonly see and treat if you want to understand what tends to go wrong and why.
What are the 7 most common mistakes when starting running again?
These are the patterns we see most often. None of them are unusual. Most are understandable. All of them are avoidable.
- Doing too much too soon
This sits at the root of most return-to-running injuries. A 6k run in week one feels manageable, so a 9k run in week two seems reasonable. It often is not. The body needs time to adapt to load, and that adaptation does not happen as fast as your motivation. - Copying your old pace or distance too early
Running your previous comfortable pace before your tissues have adapted to running again puts significant stress on structures that are not yet ready. The pace that felt easy in October may be genuinely difficult in February, regardless of how well you have maintained fitness in other ways. - Increasing mileage too quickly
Even when week one goes well, adding too much distance too quickly is a common next mistake. A jump from 12k one week to 20k the next is the kind of spike that puts stress on tendons and bone before they have adapted to the new demand. - Ignoring early warning signs
Calf tightness that settles within a day, a mild Achilles ache after longer runs, or a shin that feels tender first thing in the morning are signals worth paying attention to. They are often the body’s way of indicating that the load is slightly ahead of its current capacity. People who push through these early signals tend to end up with more significant problems. - Skipping strength work
Running places repetitive load through the calf, quad, glutes, and hip stabilisers. If those structures are weaker than they were before the break, they fatigue faster and compensate in ways that can lead to injury. A few targeted exercises done consistently can make a meaningful difference, even without a full gym programme. - Adding hills or speed work too soon
Both significantly increase the demand on tendons and soft tissue. Hill running places extra load on the Achilles and calves. Speed work increases ground reaction forces across the whole kinetic chain. These are valuable training tools once a base has been established. In the first few weeks back, they tend to cause more harm than they prevent. - Relying on motivation rather than a sensible plan
Motivation is highest at the start of a return. Sunny weather, a race entry, or a few good runs in a row can push training volume beyond what is sustainable. The runners who come back most successfully tend to be the ones who resist the urge to capitalise on feeling good and stick to a progression that the body can actually keep up with.
How quickly should I increase running mileage?
As a rough guide, avoid increasing your total weekly mileage by more than around 10 percent from one week to the next. In practice, this is only a starting point. How quickly you progress depends on how long you have been off, your current strength, your sleep, your age, and how much other physical activity you are doing alongside running.
The 10% rule is widely cited, and it is a reasonable principle, but it has limits. It does not account for the difference between someone returning after two weeks off and someone restarting after three months of very little exercise. It also does not account for what else is happening in your training: adding strength sessions, cycling, or significant amounts of walking all contribute to overall load on the lower limb.
What tends to work well is a conservative first two weeks, with gradual progression only once you are confident the initial volume is genuinely comfortable. If you are completing runs and feeling no significant fatigue in your lower legs the following day, that is a more useful signal than any percentage calculation.
If you are unsure whether your rate of progression is sensible for your specific situation, this is exactly the kind of thing a physio for runners can help you think through.
How can I prevent running injuries when returning after a break?
The most reliable way to prevent running injuries is to manage training load carefully, keep easy runs genuinely easy, include adequate recovery, and pay attention to early symptoms rather than dismissing them. Strength work, sensible progression, and adjusting the plan when something does not feel right are more useful than any particular warm-up routine or shoe choice.
In practical terms, injury prevention when returning to running tends to involve a few consistent habits:
- Build volume before adding intensity. Distance and frequency first, pace later.
- Keep easy runs easy. If most of your running feels hard, the pace is probably too high for where you are right now.
- Include rest days, not just low-mileage days. Recovery is part of the training.
- Do some lower limb strength work, even two sessions a week. Calf raises, single-leg exercises, and basic hip strengthening are a practical starting point.
- Pay attention to patterns. Achilles soreness that appears every time you exceed a certain distance, or shin pain that arrives on back-to-back days, is telling you something specific.
- Adjust early. Reducing load slightly when a niggle appears is easier than managing a full injury six weeks later.
Injury prevention is not about doing everything perfectly. It is about staying consistent enough over time to let the body adapt, and being willing to modify the plan when it gives you feedback.
The NHS provides practical guidance on how to prevent sports injuries and return to exercise safely, including advice on warming up, rest, and knowing when symptoms warrant professional attention.
For runners dealing with recurring knee pain during or after runs, a physiotherapy assessment for knee injuries can identify whether the issue relates to load, strength, or movement patterns, and guide a return to running that does not keep repeating the same cycle.
Can physio help me return to running safely?
Yes, in most cases. A physiotherapy assessment can identify movement limitations, strength deficits, or load patterns that are contributing to symptoms, and help you modify training without having to stop running entirely. For runners with recurring problems, physio often provides a clearer explanation of why the same injury keeps happening, not just how to manage it in the short term.
At ProMOTION Physiotherapy, our sports physiotherapy for runners in Edinburgh includes a thorough assessment of the factors that tend to drive running injuries: strength, mobility, loading patterns, and training history. The goal is not to tell you to rest. It is to help you figure out what is driving the problem and how to adjust without losing the progress you have made.
For some runners, particularly those with recurring Achilles, knee, or shin problems, a running-specific gait analysis can add useful detail. It is not always necessary, but when symptoms keep returning despite sensible load management, understanding how you are actually moving can help explain why certain structures are being overloaded. Our gait analysis in Edinburgh looks at running mechanics in a way that informs the rehabilitation plan, rather than as a standalone assessment.
If you have been dealing with foot or ankle symptoms alongside your return to running, physiotherapy for ankle and foot injuries may also be relevant, particularly if Achilles or plantar symptoms are part of the picture.
Sports massage can also play a useful supporting role for runners building back into training, particularly for managing calf and soft tissue fatigue during periods of increasing load.
When should you see a physio instead of trying to manage it yourself?
Most minor niggles in the first few weeks of returning to running settle with a few days of reduced load. You do not need a physiotherapy assessment every time your calves feel a bit heavy.
That said, there are situations where self-management tends not to be enough:
- Pain or tightness that keeps returning at the same point in every run, session after session
- Symptoms that are getting worse rather than staying the same or improving
- Uncertainty about how much to run or what is safe to continue
- The same injury repeating itself across multiple attempts to return
- Significant changes in how you are walking or loading the leg to avoid discomfort
- Any sharp, swollen, or significantly worsening pain that does not settle with rest
In these situations, getting an assessment earlier rather than later tends to produce better outcomes. A physiotherapist can distinguish between symptoms that simply reflect a training load issue and those that may need more specific intervention.
Our physiotherapy services at our Davidsons Mains clinic are available to runners at any stage, whether you are in the early stages of returning to running, managing a specific injury, or trying to understand why a recurring problem keeps coming back.

Frequently Asked Questions
Start with a lower volume than you think you need. Three easy runs a week with rest days in between is a sensible starting point. Avoid trying to match your previous pace or distance in the first two to three weeks. The body adapts to running load more slowly than cardiovascular fitness returns, so what feels aerobically easy may still be placing significant stress on tendons and soft tissue. Build gradually, and let consistency do the work.
Three times a week tends to work well for most people returning after a break. This allows adequate recovery between sessions while maintaining a consistent stimulus for adaptation. Running on consecutive days increases the risk of cumulative load problems, particularly in tendons. As your body adapts over several weeks, you can consider adding a fourth run, but only once three sessions per week feel genuinely manageable and symptom-free.
The 10% rule is a guideline suggesting that you should not increase your total weekly mileage by more than 10 percent from one week to the next. It provides a useful rough framework for avoiding sudden load spikes, which are one of the most common causes of running injury. It is not a precise formula, and it does not account for factors such as total training load, sleep, strength, or injury history. Use it as a guide rather than a rule, and be willing to progress more slowly if your body suggests that is what is needed.
Physiotherapy can be genuinely useful for runners returning after a break, particularly if you have experienced recurring problems or are unsure how to manage your training load. A physio assessment can identify specific strength or movement factors contributing to symptoms, help you modify training without stopping completely, and provide a structured plan for building back up. For runners with recurring injuries, understanding why the problem keeps returning is often more valuable than simply managing each episode as it arises.
