Most runners feel a small ache now and then. The hard part is knowing what to do about it.

Listen before you run

Check in with your body before the session, for example with an easy movement you know well. If it feels worse than usual, make the session shorter and easier, or take a rest day.

When to hold back and get it checked

If the pain is strong, changes your stride, keeps getting worse while you run, or comes with swelling, stop for the day. The same goes for pain you do not know the cause of. Then it is time to have it checked by a health professional before you keep running.

Small steps back

Holding back one day is rarely a loss. A shorter, easier week often gets you going again faster than pushing through.
