A Guide to Getting Back Into Running Safely
Every year, when the weather finally starts warming up, CSC+M sees the same trend in the clinic: people who spent most of the winter less active suddenly jump back into running. The motivation is great — but the body does not always love going from “hibernation mode” to 5-mile outdoor runs overnight.
Running itself is not bad for your joints or body. In fact, it can be excellent for cardiovascular health, mental health, bone density, and overall fitness. The problem usually comes from doing too much, too soon, after months of decreased activity. Here are some of the most common running injuries we treat each spring, what structures are involved, and what recovery typically looks like.
1. Runner’s Knee (Patellofemoral Pain Syndrome)
What It Feels Like
- Aching pain around or behind the kneecap
- Pain with stairs, squatting, or prolonged sitting
- Discomfort that worsens during or after runs
Structures Involved
Runner’s knee involves irritation between the:
- Patella (kneecap)
- Femur (thigh bone)
- Surrounding soft tissues, including the quadriceps tendon and patellar tendon
- Weakness in the hips and glutes often contributes to poor knee mechanics during running
Why It Happens in Spring
After a sedentary winter, the muscles responsible for controlling hip and knee alignment become weaker. When mileage suddenly increases, the knee absorbs more stress than it can tolerate.
Physical Therapy Plan of Care
Treatment typically focuses on:
- Glute and hip strengthening
- Quadriceps strengthening
- Running mechanics assessment
- Mobility work for the hips and ankles
- Gradual return-to-running program
Expected Recovery Time
- Mild cases: 2–6 weeks
- Moderate cases: 6–12 weeks
Most runners can continue modified activity while recovering if symptoms are managed early.
2. Achilles Tendinitis
What It Feels Like
- Tightness or pain in the back of the heel
- Morning stiffness
- Pain during push-off while running
- Tenderness along the Achilles tendon
Structures Involved
The primary structure affected is the:
- Achilles tendon, which connects the calf muscles (gastrocnemius and soleus) to the heel bone
Why It Happens in Spring
The Achilles tendon does not respond well to sudden spikes in workload. Going from minimal activity to hill running, sprinting, or long-distance running quickly overloads the tendon.
Physical Therapy Plan of Care
Treatment often includes:
- Calf strengthening, especially eccentric exercises
- Load management
- Ankle mobility work
- Soft tissue treatment
- Gradual plyometric progression
- Footwear assessment
Expected Recovery Time
- Mild irritation: 4–6 weeks
- Chronic cases: 3–6 months
Tendon injuries tend to recover slowly because tendons have a relatively poor blood supply.
3. Shin Splints (Medial Tibial Stress Syndrome)
What It Feels Like
- Pain along the inner border of the shin bone
- Pain at the start of runs that may improve as you warm up
- Tenderness to touch
Structures Involved
This condition involves irritation of:
- Tibia (shin bone)
- Muscles attaching to the tibia, especially the soleus and tibialis posterior
- Surrounding connective tissue
Why It Happens in Spring
Rapid increases in running volume, especially on hard surfaces, overload the lower leg tissues before they have adapted.
Physical Therapy Plan of Care
Treatment focuses on:
- Reducing training load temporarily
- Strengthening calves and foot stabilizers
- Improving running mechanics
- Addressing ankle mobility
- Gradual return to impact activity
Expected Recovery Time
- Mild cases: 2–4 weeks
- More irritated cases: 6–8 weeks
Ignoring shin splints can eventually progress into stress fractures.
4. Plantar Fasciitis
What It Feels Like
- Sharp heel pain, especially with the first steps in the morning
- Tightness in the arch of the foot
- Pain after prolonged standing or running
Structures Involved
The affected structure is the:
- Plantar fascia, a thick band of connective tissue along the bottom of the foot
Why It Happens in Spring
Sudden increases in walking and running volume place repetitive strain on the foot tissues, especially in runners with tight calves or poor foot mechanics.
Physical Therapy Plan of Care
Treatment may include:
- Calf stretching
- Foot intrinsic strengthening
- Manual therapy
- Taping techniques
- Load management
- Shoe recommendations
Expected Recovery Time
- Mild cases: 4–8 weeks
- Chronic cases: several months
Consistency is extremely important with plantar fasciitis rehab.
5. IT Band Syndrome
What It Feels Like
- Sharp or burning pain on the outside of the knee
- Symptoms worsening with longer runs
- Pain often appears after a certain mileage threshold
Structures Involved
The condition involves irritation of the:
- Iliotibial band (IT band)
- Tissue near the outer knee, particularly around the lateral femoral epicondyle
Why It Happens in Spring
- Weak hip stabilizers, combined with increased mileage, often create excessive tension in the IT band.
Physical Therapy Plan of Care
Treatment commonly includes:
- Hip and glute strengthening
- Running form analysis
- Mobility exercises
- Training modifications
- Gradual mileage progression
Expected Recovery Time
- Mild cases: 4–6 weeks
- Persistent cases: 2–3 months
How to Prevent Spring Running Injuries
The best injury prevention strategy is gradual progression. A few general recommendations we give patients:
- Increase mileage slowly (usually no more than 10% weekly)
- Start with walk/run intervals if you were inactive during winter
- Strength train 2–3 times per week
- Prioritize sleep and recovery
- Replace worn-out running shoes
- Warm up before runs
- Avoid suddenly adding hills or speed work
Your cardiovascular system often adapts faster than your muscles and tendons. Just because your lungs feel ready does not mean your tissues are conditioned for repetitive impact yet.
When to See a Physical Therapist
It is normal to experience soreness when returning to exercise. It is not normal for pain to:
- Persist during daily activities
- Alter your running form
- Continue worsening week to week
- Cause swelling or instability
- Prevent you from training consistently
The earlier an injury is addressed, the easier it usually is to treat! Don’t let spring running pain turn into a season-ending injury. If knee, shin, heel, or foot pain is slowing you down, schedule a session with a NYC physical therapist at CSC+M in Flatiron. Our team can assess your mechanics, identify the cause of the issue, and develop a personalized plan to help you recover safely and return to running with confidence.
