Shin splints — medically known as medial tibial stress syndrome (MTSS) — is one of the most common running injuries I see, and one of the most frustrating for patients who have a race on the horizon. The question I hear most often is: do I have to stop running?
The honest answer is: not necessarily. In most cases, you can continue running at a reduced load while addressing the underlying cause. Complete rest is rarely the best solution — and often makes things worse in the long run.
What Are Shin Splints?
Shin splints refer to pain along the inner edge of the shinbone (tibia), typically in the lower two-thirds of the leg. The pain usually develops during a run, is diffuse along a stretch of the shin (rather than at a single point) and eases with rest — at least initially.
The underlying issue is overload of the tibia and the muscles that attach to it. The bone and surrounding tissue are absorbing more stress than they can currently handle. The solution isn't to stop all loading — it's to reduce load to a manageable level and build capacity progressively.
Can I Keep Running?
In most cases, yes — with modification. The key is finding a training load that allows symptoms to settle after each run, rather than accumulating over days and weeks. A simple rule: if pain during a run stays below 3 out of 10 and returns to baseline within 24 hours, you can continue at that level.
What usually needs to change:
- Reduce weekly mileage by 30–50% initially
- Avoid back-to-back running days — give the tibia 48 hours between sessions
- Avoid hills and speed work until symptoms settle
- Switch some runs to lower-impact cross-training — cycling, swimming or pool running maintain fitness without tibial load
Running through severe pain (5+ out of 10) or continuing when pain doesn't settle within 24 hours is where shin splints become serious. This pattern leads to stress reactions and eventually stress fractures — a much longer recovery.
How Long Do Shin Splints Take to Heal?
With proper load management and rehabilitation:
- Mild cases: 2–4 weeks to return to normal training
- Moderate cases: 4–8 weeks
- Severe or long-standing cases: 8–12 weeks
Runners who ignore shin splints and train through them typically take 3–4 months to recover. Early management is significantly more effective than waiting.
What Causes Shin Splints?
Shin splints are almost always caused by a combination of factors — rarely just one thing. The most common:
Too much, too soon
The most common cause. Increasing mileage, frequency or intensity faster than the tibia can adapt. The 10% rule — never increasing weekly mileage by more than 10% — exists for good reason.
Weak calf and hip muscles
Weakness in the calf complex and hip abductors means more stress transfers to the tibia with every footstrike. Strengthening these muscles is the cornerstone of shin splint rehabilitation — not stretching.
Running surface
Hard surfaces (road, concrete) generate higher ground reaction forces than grass or trail. Runners who suddenly switch from mixed terrain to all-road running are at higher risk.
Footwear
Worn-out running shoes lose their shock absorption. As a guide, most running shoes should be replaced every 400–600 miles.
Shin Splints vs Stress Fracture — How to Tell the Difference
Important: If your shin pain is at a very specific point (you can point to it with one finger), doesn't ease during a run, is present at rest or at night, or followed a significant increase in training, you may have a stress fracture rather than shin splints. Stop running and get assessed by a physiotherapist before continuing.
What Treatment Actually Works
The evidence for shin splint treatment is clear. What works:
- Load management — reducing training load to a tolerable level while maintaining some running
- Progressive calf strengthening — eccentric calf raises are the most evidence-supported exercise for MTSS
- Hip strengthening — glute and hip abductor exercises reduce tibial stress significantly
- Gradual return to full training — progressive mileage increases once symptoms settle
What doesn't work well in isolation: foam rolling, stretching, ice, rest alone. These may provide temporary relief but don't address the underlying cause.
