Plantar Fasciitis & Return to Running

A step-by-step guide for runners recovering from heel pain

Plantar fasciitis is one of the most common foot problems in runners. The plantar fascia -- a thick band of tissue that fans out from the heel to the base of the toes -- develops tiny tears from repeated stress that outpace the body's ability to repair them (the problem is now understood to be more degenerative than inflammatory).
The hallmark symptom is sharp pain with the first step in the morning.
Running through the pain greatly delays recovery, so a gradual return-to-running plan is essential.

1
Repeated impact on the sole from running

Each foot strike puts 2 to 3 times your body weight on the plantar fascia

2
Micro-tears accumulate

A sudden increase in mileage or tight calf muscles add extra strain to the fascia

3
Degenerative change builds up in the fascia

Pain focuses on the inner front part of the heel

4
Pain is worst after rest

The fascia tightens during sleep, and that first step in the morning stretches it suddenly

🦶 Flat feet or high arches 📈 Sudden increase in training 🦵 Tight calf muscles ⚖️ Body weight load on the foot
📅
10 to 14 consecutive pain-free days in daily life
🚶
30 to 45 minutes of continuous walking with no pain
👆
No tenderness when pressing the heel
🦘
Single-leg hopping with no pain
🌅
Morning first-step pain has completely gone
📝
Note: these criteria and timeframes are only a guide. Even once the pain is gone the fascia needs more time to recover, so decide when to start running again together with your doctor
🚶
Step 1 (Weeks 1-2)
Start with 30-minute walks
🏃‍♂️
Step 2 (Weeks 3-4)
Alternate 5 min walk / 1 min jog for 20-30 min total
🏃
Step 3 (Weeks 5-6)
Gradually increase the jogging ratio
🏅
Step 4 (Week 7-8+)
Build up to 20-30+ min of continuous jogging
🧘
Daily Stretching
Stretch both the plantar fascia (pull the ankle and toes back to stretch the sole) and the calf: hold 30 seconds x 3 sets each
📏
The 10% Rule
As a guide, increase weekly mileage by no more than 10% over the previous week
🌿

80 to 90% of patients are reported to improve with proper conservative treatment

Most runners are reported to improve within 6 to 18 months. Extracorporeal shockwave therapy has been reported to help reduce pain, but the response varies from person to person (temporary pain, redness, swelling or bruising can occur at the treated area). A patient, step-by-step approach leads to an earlier return in the long run.

⚠️

Caution during the acute phase
Bamboo foot rollers and golf ball massage are not recommended during the acute phase. Also, pain that worsens after activity -- even if it felt fine during activity -- is a sign that the load on the fascia is too high. Continuing to run through pain can extend recovery to 3 to 4 months.

💡 4 Habits to Prevent Recurrence

  • Make stretching both the plantar fascia (sole of the foot) and the calf a habit
  • Replace running shoes every 500 to 800 km
  • Avoid sudden increases in training -- use the 10% rule as a guide
  • Weight management is also an important part of preventing recurrence
