Plantar Fasciitis: A Runner's Guide to Getting Back on Your Feet

Plantar fasciitis is the most common cause of heel pain in runners, and one of the most frequently mismanaged. It affects non-runners too: people who stand all day, have recently gained weight, or have changed footwear. The classic presentation is sharp pain in the heel or arch, worst with the first few steps in the morning or after prolonged sitting, that eases once you're warmed up but returns after exercise. If that description sounds familiar, you almost certainly have plantar fasciitis.

What is the plantar fascia?

The plantar fascia is a thick band of connective tissue that runs from the heel bone to the base of the toes. It acts as a passive shock absorber and supports the arch of the foot during loading. Plantar fasciitis (more accurately termed plantar fasciopathy) occurs when the tissue is overloaded and develops degenerative changes, not true inflammation, despite the name. It goes through the same reactive process as a tendinopathy: disorganisation, thickening, and sensitisation of nerve endings.

Why does it happen?

The root cause is almost always a rapid increase in load, whether running more volume, adding hills or speed work, or returning to running after a break. Prolonged standing, weight gain, and inadequate footwear do the same for non-runners. Contributing factors include calf tightness, reduced ankle dorsiflexion range, weakness in the foot intrinsic muscles, and running in worn-out shoes. Contrary to popular belief, flat feet are not always the culprit.

What doesn't help

Resting completely is rarely effective long term: the pain returns when activity resumes. Generic calf stretching helps a little but is not sufficient on its own. Orthotics can offload symptoms short-term but don't address the underlying issue. Night splints have modest evidence for morning pain specifically. Cortisone injections can provide short-term relief but don't change the underlying pathology and carry a risk of fat pad atrophy with repeated use.

What actually works for treatment

The evidence on plantar fasciitis treatment is much clearer than most people realise. High-load calf and plantar fascia loading exercises, performed with progressively increasing resistance, are consistently the most effective intervention. Towel toe scrunches and short-foot exercises activate the intrinsic foot muscles. Progression to single-leg heel raises with the toes in extension loads the fascia directly through the windlass mechanism.

• Progressive heel raise loading (eccentric and isometric protocols)
• Intrinsic foot muscle strengthening
• Ankle mobility work to improve dorsiflexion range
• Load management: adjusting running volume, not stopping completely
• Review of footwear and surface variation

How long does recovery take?

With appropriate loading-based treatment, most runners see significant improvement within 6–8 weeks. Complete resolution can take 3–6 months depending on chronicity. The key insight: you don't need to stop running, you need to manage load while progressively building tissue capacity. Running at manageable pain levels is generally fine, and many runners continue training throughout recovery with appropriate modifications.

Getting assessed in the Eastern Suburbs

Seth sees a high volume of plantar fasciitis presentations across the Eastern Suburbs, from Bondi Beach runners and Centennial Park regulars to coastal walkers from Bronte to Coogee. A home visit assessment can identify the specific drivers in your case and get you on an evidence-based loading program from day one.
