Plantar fasciitis · 6–12 weeks
Plantar fasciitis is heel pain — worst with the first steps in the morning or after sitting. It's a degenerative condition of the plantar fascia, not pure inflammation. The fix is loaded tendon-style rehab (eccentric calf raises and progressive plantar fascia loading), not rest alone.
Most athletes don't need a full running layoff. Volume reduction + targeted rehab + supportive shoes is usually enough. Recovery takes 6–12 weeks of consistent rehab work — there's no shortcut.
Stage 1 — Acute (weeks 1–2)
Drop weekly mileage 30–50%. Cut hills and speed work. Begin twice-daily eccentric calf raises off a step (3×15 with knee straight, 3×15 with knee bent). Stretch the plantar fascia 3× daily by pulling toes back gently. Wear supportive shoes at home — no barefoot walking on hard floors.
Stage 2 — Build (weeks 3–6)
Begin towel curls (foot scrunches with a towel), marble pickups, and single-leg calf raises with progressive load. Continue eccentric work. Volume can stay reduced until morning pain drops below 3/10 — usually 4–6 weeks for most athletes.
Stage 3 — Return (weeks 5–10)
Once morning heel pain is consistently below 2/10, rebuild volume 10% per week. Reintroduce hills only after 6 weeks of pain-free running. Speed work last. Continue strength rehab 3× per week ongoing.
Stage 4 — Prevention (weeks 8+)
Eccentric calf raises and fascia loading should remain in your strength routine permanently if you've had plantar fasciitis once. Recurrence rate without ongoing maintenance is 40–60%. Treat it like a chronic management situation, not a one-and-done.
Eccentric calf raises on a step (Alfredson protocol). 3×15 with straight knee, 3×15 with bent knee. Twice daily for 12 weeks. The single most effective intervention in the published literature.
Plantar fascia-specific stretching: cross your injured leg over the other knee, grip your toes, and pull back until you feel a stretch in the arch. 10 reps × 10 seconds, 3× daily. Best done before getting out of bed in the morning.
Foot intrinsic strength: towel scrunches, marble pickups, short-foot exercise (lifting the arch without curling toes). 3 sets of 15, daily.
Calf and ankle mobility: foam roll calves, ankle dorsiflexion stretches. Limited ankle dorsiflexion is a major contributor.
Footwear: supportive trainers (not minimalist) during recovery. House shoes or recovery sandals at home. Avoid barefoot on hard floors.
Plantar fasciitis night splints: mixed evidence; most athletes don't tolerate them.
Cortisone injections: short-term pain relief but increase risk of plantar fascia rupture. Use as last resort after 12+ weeks of failed conservative care.
Shockwave therapy: some evidence for chronic (>6 month) cases. Not first-line.
Generic orthotics from a pharmacy: cheap and sometimes help, but custom orthotics are usually not needed if you're doing the rehab. Save your money.
Most athletes are pain-free within 6–12 weeks with consistent rehab. A third take longer, especially if rehab is inconsistent or load doesn't drop enough. Chronic cases (>12 months) require more intensive intervention but still respond.
If morning pain stays below 4/10 during the day and doesn't worsen after runs, yes — reduced-volume running is fine. If morning pain is 7+/10 or runs make it worse for days, take 1–2 weeks completely off running and focus on rehab.
Soft heel cups can reduce morning pain. Cheap, low downside, try them. Custom orthotics rarely outperform a good shoe + heel cup + rehab combo for most athletes.
The plantar fascia contracts overnight. The first steps stretch it suddenly, which feels sharp. Doing the toe-pull stretch before getting out of bed reduces the morning sting significantly.
Yes. Cycling, swimming, and elliptical are usually all fine. Avoid jumping sports and barefoot activities like beach volleyball. Pool running is great because it's zero-impact and preserves running mechanics.
SportPlan reduces volume automatically when you flag foot pain and reintroduces hills only after a clean stretch of pain-free running. See your first week before you pay. €9.99/month, cancel anytime.
