Shin Splints: Why Stretching More Won't Fix It
Quick answer: Shin splints (medial tibial stress syndrome, MTSS) is bone-loading overload - the inner shinbone isn't adapting fast enough to the running mileage you're asking of it. It's not a flexibility problem, not a "tight calf" problem, not something you can stretch away. The fix is load management + calf and foot strength - and crucially, catching it early before it progresses to a stress fracture.
What it feels like
- Diffuse ache along the inner third of the shin, roughly the lower two-thirds of the tibia
- Hurts at the start of a run, often eases mid-run, returns after
- Tender when you press along the inner border of the shin - tenderness is spread over 5 cm or more, not pinpoint
- Usually bilateral (both shins) in novice runners; unilateral more often in seasoned runners with a technique or mileage issue
When it's something worse
If tenderness becomes pinpoint (less than 5 cm), pain persists at rest, or a "hop test" on that leg is sharp and localised, suspect tibial stress fracture. That needs imaging (bone scan or MRI) and at least 6-8 weeks of non-running. Don't wait.
Why it happens
Running is a bone-loading activity. With each step, the tibia flexes microscopically and the body responds by laying down new bone. That process is slow - bone adapts over 4-8 weeks, not days. If you increase mileage faster than that, microdamage accumulates faster than repair, and pain starts.
Common triggers:
- Mileage jumped more than 10% in a week
- Pace or gradient change (lots of downhill)
- New shoes, especially a big stack-height or stiffness change
- Return from a break, assuming you're at the same fitness
- Body-weight change without gradual loading
- Poor calf strength (single-leg calf raise under 20 reps is a red flag)
The fix
Phase 1: reduce the load (2-3 weeks)
Not zero. Drop mileage by 30-50%, remove hills and speed work, keep easy running that doesn't reproduce pain beyond 2/10. If any running hurts, cross-train (bike, pool-running, elliptical) to maintain cardiovascular base.
Phase 2: build the tibia's capacity (4-8 weeks, overlapping Phase 1)
- Calf strength - heavy slow raises, 3 × 10-12 with full range, every other day; progress to single-leg.
- Foot intrinsics - short-foot exercise, toe spreads, balance on one leg.
- Hip strength - glute medius drills (weak hip drops the pelvis, increases tibial load).
- Gradual mileage return - no more than 10% per week, and insert a "down week" every 3 weeks.
Phase 3: technique and terrain
- Cadence - if you're running below 160 steps/minute, a small cadence increase (5-8%) reduces overstride and tibial load without changing pace.
- Terrain - mix softer surfaces (grass, rubber track) into a few runs per week while healing.
- Shoes - don't chase a specific shoe type; just avoid radical changes mid-flare.
What doesn't help (much)
- Static stretching of the calves before running
- Foam rolling as the only intervention
- Compression sleeves - they feel nice, they don't change healing
- Pushing through pain "because it's just shin splints" - this is how you end up with a stress fracture

Running gait analysis is useful in recurring cases. Expect RM80-150 per session, usually 4-6 sessions spread across 6-8 weeks while you progress load at home. WhatsApp us if you want an assessment before your next race block.
