Summer running niggles: shin splints, plantar fasciitis, and Achilles pain—what your body is compensating for

Running Legs in Motion

The longer days and warmer weather make summer an irresistible time to run. But it's also when we see a familiar influx of injuries at the clinic — shin pain, heel pain, and Achilles tightness that runners can't quite shake.

These aren't random. They're compensation patterns. And understanding what's driving them is the key to getting back on track.

Why Summer?

The most common culprit is a sudden spike in training load. After a quieter winter, many runners increase mileage, pace, or frequency too quickly. Add harder surfaces, lighter footwear with less support, and mild dehydration affecting tissue elasticity — and you have the perfect conditions for overuse injuries.

Shin Splints

Pain along the inner shinbone is typically a sign that the surrounding muscles and connective tissue are overloaded. But shin splints are rarely just a shin problem. Weak hip abductors, reduced ankle mobility, or overpronation all shift excessive force into the tibia.

What helps: Reduce mileage, ice post-run, strengthen the hips and glutes, and reintroduce running gradually using the 10% rule (no more than a 10% mileage increase per week).

Plantar Fasciitis

That sharp heel pain on your first steps in the morning is the hallmark of plantar fasciitis — inflammation of the thick tissue band running along the sole of the foot. Tight calves are almost always a contributing factor, increasing tension through the Achilles and into the plantar fascia. Poor hip extension and overpronation add to the load.

What helps: Calf and plantar fascia stretches before getting out of bed, rolling the foot over a frozen water bottle, eccentric heel drops, and supportive footwear. Left unaddressed, this one tends to become chronic — early action matters.

Achilles Tendinopathy

Stiffness or pain at the back of the ankle, often worse after rest or first thing in the morning, is a common sign of Achilles tendinopathy. Speed work and hill running are common triggers. Crucially, complete rest makes it worse — tendons need the right kind of load to heal.

What helps: Eccentric calf strengthening (the gold standard), a temporary reduction in running volume, avoiding aggressive stretching into pain, and a short-term heel raise to reduce tendon load.

The Common Thread: Compensation

All three injuries share an underlying pattern. When one area of the body is weak or restricted, another absorbs the extra demand — until it can't any more. Weak glutes overload the shins and feet. Stiff hips alter foot strike. An old ankle sprain changes how force travels up the leg.

This is why treating just the painful area often brings only temporary relief. Lasting recovery means addressing what the body has been compensating for.

When to Get Assessed

Self-care goes a long way, but seek professional help if:

• Pain persists beyond 2–3 weeks

• Symptoms are worsening, not settling

• The same injury keeps recurring

An osteopath can identify the mechanical root cause, provide hands-on treatment, and guide a graduated return to running specific to your body.
