Plantar Fasciitis in Runners
Plantar fasciitis is pain along the bottom of the foot, usually near the heel, caused by irritation of the plantar fascia, a band of tissue connecting the heel to the toes. It's a common complaint among runners and often has a distinctive pattern: sharp with the first steps out of bed, easing somewhat once you've been moving for a few minutes, then sometimes returning after longer periods on your feet.
What plantar fasciitis actually is
The plantar fascia absorbs a lot of load with every stride, and repeated strain beyond what it's adapted to can lead to irritation and pain, usually at or near where it attaches to the heel bone. It tends to build gradually rather than from a single incident, and the classic first-steps-in-the-morning pain pattern is one of the more recognizable signs, though a proper diagnosis should come from a professional rather than self-assessment.
Common causes
- A sudden increase in running mileage or time spent standing
- Worn shoes or footwear with inadequate support for your foot type
- Tightness in the calf muscles and Achilles tendon
- Running consistently on hard surfaces
- Extended periods barefoot or in unsupportive footwear off the run
General management approaches
Reducing running load while symptoms are active, alongside calf and foot stretching, is a common starting point many runners use. Supportive, well-fitted shoes both for running and everyday wear can also reduce ongoing strain; see how to choose running shoes for your first race for guidance on fit.
Some runners find gentle calf and foot mobility work genuinely helpful as part of a broader routine; see stretching before and after running for a practical approach to both dynamic and static work. Gradually easing back into full mileage, rather than resuming a previous training load immediately, tends to reduce the chance of symptoms returning.
Footwear and running surfaces
Alternating running surfaces where possible, favoring softer options over consistently hard pavement, is a small adjustment some runners find useful alongside other changes. Replacing shoes on a reasonable cycle, generally before they've lost meaningful cushioning and support, is a similarly low-effort habit worth building.
When to see a doctor or physiotherapist
Heel pain that persists beyond a few weeks despite reduced load, worsens over time, or is severe enough to change how you walk should be evaluated by a doctor or physiotherapist rather than managed indefinitely on your own. They can confirm the diagnosis and recommend a plan suited to your specific case. For an overview of other common overuse injuries in runners, see common running injuries.

Browse eventsBased on what we see in support conversations, foot and heel pain mentions seem to tick up around the same weeks each cycle, roughly when longer training runs start showing up in most beginner plans, though I'd call that a loose pattern rather than a hard number. My honest suggestion, purely from a platform vantage point, is to check your event's deferral or transfer policy on the category page well before race week if a niggle is starting to affect your training, since some organizers need more notice than others.
Frequently asked questions
Why does plantar fasciitis hurt most in the morning?
The fascia tightens overnight, so the first steps after waking often stretch it suddenly, which is why morning pain is such a common and recognizable symptom.
Can I keep running with plantar fasciitis?
Some runners reduce mileage rather than stop completely, but persistent or worsening heel pain is a reason to cut back further and get it assessed.
Do shoes matter for plantar fasciitis?
Supportive, well-fitted footwear for both running and daily wear can reduce ongoing strain on the foot, though it's usually one part of a broader approach.
How long does plantar fasciitis take to improve?
It varies by individual, often weeks to months with consistent management, so a physiotherapist can give a more specific expectation based on your case.
