This guide shows how to warm up the calf and plantar fascia, adjust the run itself, and recover afterward. Plantar fasciitis is irritation of the thick tissue band under the foot.
It causes stabbing pain in the bottom of the foot near the heel. Pain is worst after rest. Runners, people who are overweight, and people who stand on hard surfaces face higher risk, according to the Mayo Clinic overview of symptoms and causes.

Can I run today?
Runners with only mild irritation can often keep running with changes. Active Physical Therapy and Sports Medicine advises avoiding rapid mileage or speed increases, choosing softer and even surfaces, and stopping activities that cause foot pain. Use that as a day-by-day check.
Keep distance and pace flat when the heel feels mildly stiff but warms up. Pick a level park path over cambered concrete. End the run if sharp heel pain starts.
How do I warm up the fascia and calf?
Tight calves increase strain on the fascia, and stretching is first-line treatment. Hospital for Special Surgery guidance recommends calf stretching plus plantar-fascia massage before running, as explained in this Hospital for Special Surgery heel-pain guide. Do this short routine before leaving:.
- Walk briskly for five minutes to raise tissue temperature.
- Stretch each calf against a wall, knee straight then bent.
- Roll the arch gently over a ball for one to two minutes.
- Pull toes back and rub the thumb along the arch.
What should I wear and where should I run?
Adequate arch support is essential during runs. Mayo Clinic Health System recommends supportive cushioned sneakers, avoiding barefoot walking, and discussing over-the-counter or custom orthotics with a clinician, as detailed in these Mayo Clinic Health System running tips. Apply the same idea to route choice.
Favor track, turf, or smooth trail over hard sidewalks. Avoid hills and sudden speed work while symptoms persist. Replace a run with swimming or cycling when the foot needs less impact, a swap UC Davis Health supports for maintaining fitness.
How do I recover after the run?
Rest the foot after running and add calf and plantar stretching. UC Davis Health describes RICE recovery as rest, ice on the sore heel for 20 minutes three to four times daily, stretching, and ibuprofen if tolerated, as outlined in this UC Davis Health treatment guide.
For chronic soreness, try the seated stretch cited by the American Academy of Orthopaedic Surgeons: cross the foot, pull the toes back, and rub the thumb along the fascia. The exact cause is poorly understood and no single treatment works for everyone. Over 98% improve without surgery, so get clinician evaluation for persistent pain rather than running harder.
