Achilles pain when running is common—but the key question is whether it’s something you can run through or something that will get worse if you don’t address it.
If you’re feeling pain in the back of your ankle or lower calf, this guide will help you understand what’s causing it and what to do next.
Can You Keep Running With Achilles Pain?
- ✔ Mild stiffness that improves as you warm up → you may be able to continue
- ⚠️ Pain that worsens during or after running → reduce activity
- 🚨 Sharp pain, swelling, or tightness that limits movement → stop running
Why Your Achilles Hurts When Running
The Achilles tendon connects your calf muscles to your heel. Running places repeated stress on this area, especially with increased training load.
- Overuse: Sudden increase in mileage or intensity
- Tight calves: Increased strain on the tendon
- Poor recovery: Not enough rest between runs
- Running mechanics: Increased load on the tendon
