3 Achilles Pain Mistakes Runners Make (and How to Dodge Them)

3 July 2025

blog post on achilles pain mistakes that runners make by a podiatrist

In the time it takes to brew a flat white, about four minutes, you will walk through the three Achilles Pain Mistakes that keep tendons grumpy, see the behavioural quirks behind each one, and pick up small yet high-leverage tweaks you can start today. Expect a clear checklist to judge whether self-management will do or a guided plan is wiser, capped with a link to our free seven-day Tendon Time course.

Emily loved her early laps around Princes Park, until her Achilles started to complain. A dull ache soon became a sharp stop-running signal.

In clinic I meet an Emily every week. The pattern is familiar: a small warning sign appears, daily life stays busy, and that warning turns into ongoing pain. Below are three common missteps that keep Achilles pain around and the simple changes that lead to steady improvement.

Achilles Pain Mistake 1 | Ignoring Morning Stiffness

Morning stiffness is not just “getting older.” It is your tendon saying

“I am carrying more load than I can manage.”

Quick adjustments

  • Runners: Shift sessions to a conversational pace for the next two weeks.
  • Walkers: Keep routes flat and shorten total distance.
  • All: Place a ten-millimetre heel lift in both shoes to lower tendon strain. (even better, make sure you have the right shoes for your Achilles tendonitis)

Reduce load now to prevent the path from stiff → sore → sidelined.

Achilles Pain Mistake 2 | Relying on Stretching Alone

Calf stretching may feel pleasant, but it rarely solves the problem. Pulling on an irritated Achilles tendon risks more irritation. Controlled strength work is the key.

A Better Approach

  • Stand on a step with heels free.
  • Rise slowly on both feet.
  • Pause one second at the top.
  • Lower with control until heels drop just below the step.
  • Keep pain at or below three out of ten.
  • Complete three sets of eight every second day.

Slow, heavy loading prompts the muscle-tendon unit to adapt so it can handle future stress. Also, if you want to know why I really can’t tolerate calf stretching? Check out why it feels good but calf stretching does not work.

Achilles Pain Mistake 3 | Waiting Too Long for Guidance

If pain stays beyond two weeks despite the changes above, or rises above three out of ten, a personalised plan is needed.

Ask your clinician

  1. Is my pain located in the mid-portion or near the insertion?
  2. Which stresses are driving my symptoms, compression or tension?
  3. What is a realistic timeline to return to comfortable running or walking?

Clear answers provide a clear plan. Vague answers are a sign to keep looking.

Before and After

BeforeAfter
Rise from bed with a hobble.Stand up with minimal tightness.
Cancelled runs and shorter walks.Back to regular sessions without pain spikes.
Stretching without progress.Structured strength and measured progress.
