Expert writing Tips

Best practice

When describing past routines or habits, "used to run" effectively conveys that the action no longer occurs. Be clear if the action has stopped completely or simply decreased in frequency.

Common error

Avoid using "used to run" when you mean an action still occurs occasionally. Instead, reserve "used to" for actions that have largely or entirely ceased. Use present tense or adverbs of frequency like "sometimes" or "occasionally" to describe present activities.
