Why so many people are getting back into running — and how you can start without getting hurt
Running is one of the most democratic exercises in the world. It doesn’t require a gym, doesn’t need sophisticated equipment, and can be done practically anywhere — from your neighborhood park to the sidewalk in front of your house. Perhaps that’s why, with every new year, millions of people add “start running” to their list of goals. The problem is that many quit within the first few weeks, often because of pain, injuries, or simply the feeling that “I wasn’t born for this.”
The good news is that almost no one is born a runner. The human body is adaptable, and sports science has shown that beginners can achieve significant results with gradual progression and method. The secret isn’t in running faster or farther right away — it’s in respecting your body’s limits while it adapts to a new demand.
If you’ve tried before and quit, or if you’re thinking about taking your first step now, this guide was made for you. Here you’ll find general guidance, based on consolidated principles of sports training, to start running safely and progressively. Remember: general information does not replace the assessment of a healthcare professional or fitness educator, especially if you have preexisting conditions.
Why do beginners get hurt so often?
The most common injury among those starting to run doesn’t come from a stumble or a fall. It comes from excess. The body takes longer to adapt than the mind imagines. While motivation tells you to run every day, tendons, ligaments, and joints are still trying to keep up.
The most frequent injuries in beginner runners include:
- Shin splints (medial tibial stress syndrome): pain in the front of the leg, very common in those who increase volume quickly
- Iliotibial band syndrome: pain on the lateral side of the knee, linked to hip weakness and excessive training
- Plantar fasciitis: inflammation on the sole of the foot, which usually appears with incorrect gait or inadequate shoes
- Patellar tendinitis: pain below the kneecap, frequent in those who ignore muscle strengthening
- Hip and lower back pain: generally associated with poor posture and lack of mobility
The common denominator of almost all these injuries is the same: doing too much, too soon. The 10% rule — never increasing weekly training volume by more than 10% — is one of the most cited guidelines in fitness education to prevent exactly this problem.
Before you start running: what you need to check
Before you take your first stride, some basic precautions make all the difference.
Assess your health
If you’re sedentary, over 35 years old, have a family history of heart disease, high blood pressure, diabetes, or any other health condition, consult a doctor before starting. A simple check-up can identify contraindications and make your practice much safer.
Choose the right shoes
You don’t need the most expensive model in the store, but you do need shoes appropriate for running. Gym shoes, walking shoes, or casual shoes have different cushioning and structure than running shoes, and can increase injury risk. Ideally, visit a specialty store and ask for guidance on your gait type (neutral, pronated, or supinated). Many stores offer free gait analysis.
Dress for the weather
Light, sweat-absorbing clothing prevents chafing and discomfort. On hot days, prefer quick-drying technical fabrics. On cold days, capes or long-sleeved shirts help maintain temperature — but avoid heavy layers that trap excessive heat during effort.
The method that works: walk before you run
The most effective — and most underestimated — strategy for beginners is the walk-run method (also called run-walk). The idea is simple: you alternate periods of walking with periods of running, gradually increasing running time over the weeks.
This approach has solid grounding in endurance training and was popularized by coaches and running programs worldwide. It respects both the cardiovascular system’s and the musculoskeletal system’s adaptation time simultaneously.
See an example of progression for the first six weeks:
- Week 1: Walk for 5 min (warm-up), alternate 1 min easy running + 2 min walking, repeat 6 to 8 times, finish with 5 min walking
- Week 2: Alternate 1.5 min running + 2 min walking, repeat 6 to 8 times
- Week 3: Alternate 2 min running + 1.5 min walking, repeat 6 times
- Week 4: Alternate 3 min running + 1 min walking, repeat 5 times
- Week 5: Alternate 5 min running + 1 min walking, repeat 4 times
- Week 6: Try running 15 to 20 minutes continuously at a comfortable pace
Recommended frequency: 3 times per week, with at least one rest day between sessions. Rest days aren’t laziness — that’s when your body actually adapts and gets stronger.
Pace, breathing, and posture: the three pillars for beginners
Pace
The most classic beginner mistake is starting too fast. A good parameter: you should be able to talk while running. If you’re so breathless that you can’t speak complete sentences, you’re going too fast. This simple criterion is called the “talk test” and is widely used by trainers to calibrate the intensity of aerobic workouts.
Breathing
There’s no universal, proven breathing technique for running. What works for most people is breathing naturally, without forcing rigid patterns. Breathing through both your nose and mouth simultaneously tends to be more efficient during effort. If you feel intense shortness of breath, reduce your pace or alternate with walking.
Posture
Some basic posture adjustments help save energy and reduce impact:
- Torso slightly tilted forward (not bent, but with a natural lean from the ankles)
- Arms bent at about 90 degrees, swinging front to back, without crossing the center of your body
- Gaze directed forward, not at the ground
- Soft landing, avoiding landing with the heel far ahead of your body
- Short, frequent steps tend to be more efficient and less aggressive on joints than long strides
Warm-up, rest, and recovery: what can’t be missed
Many people skip the warm-up due to lack of time or thinking it’s unnecessary. It’s a mistake. A 5 to 10-minute warm-up with brisk walking and dynamic movements (like knee lifts, backward kicks, and hip rotations) prepares muscles and joints for effort and reduces injury risk.
After training, static stretching — holding each position for 20 to 30 seconds — helps with flexibility and can contribute to the feeling of recovery, although scientific literature still debates its direct impact on injury prevention. What is consensus is that staying well hydrated before, during, and after exercise is fundamental, especially on hot days.
Sleep is also a recovery component that’s often overlooked. It’s during nighttime rest that your body repairs muscle micro-tears and consolidates the physiological adaptations from training.
When to stop and when to seek help
Differentiating good pain (normal muscle fatigue after effort) from bad pain (a sign of injury) is a skill that develops over time. Some alerts that demand immediate attention:
- Sharp or stabbing pain during running
- Pain that persists at rest, especially at night
- Swelling, redness, or heat in any joint
- Pain that worsens progressively with each workout
- Any chest discomfort, dizziness, or intense shortness of breath
In these cases, stop training and see a healthcare professional. Pushing through pain is the fastest way to turn a small injury into a big one.
Staying motivated beyond the first few weeks
Initial motivation tends to be high. The challenge is maintaining it after the second or third week, when the novelty wears off and fatigue appears.
Some strategies that usually work:
- Set a concrete goal: a 5 km race, for example. There are road races in practically every Brazilian city throughout the year
- Record your workouts: apps like Strava, Nike Run Club, or simply a spreadsheet help you visualize progress
- Find company: running with someone — a friend, a neighborhood running group, or online community — increases commitment
- Vary your routes: exploring new places makes training more interesting. Who knows, maybe a run in a different city while traveling? Brazil has little-known destinations worth the trip that can lead to memorable workouts
- Celebrate small wins: your first complete week, your first kilometer non-stop, your first month — every milestone matters
Conclusion: the secret is consistency, not speed
Starting to run doesn’t require talent or previous fitness. It requires patience, method, and respect for your own body. Most people who quit in the first few weeks didn’t fail due to lack of willpower — they failed because they tried to run before they were ready.
With gradual progression, respected rest days, appropriate shoes, and attention to your body’s signals, any sedentary person can build a solid running foundation over a few months. The goal isn’t to become an elite athlete — it’s to gain health, energy, and that good feeling of finishing a workout knowing you did something for yourself.
Take the first step. Literally.
